According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).
[0052] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)).

[0097] According to one embodiment of the present disclosure, the electronic device (101) may include at least one shield can (341, 344). That is, in the embodiment, the electronic device (101) may include one or more shield cans (e.g., at least one shield can).

The heat dissipation material (350) may absorb heat generated from an electronic component (E1) through the third surface (321).
[0102] According to one embodiment of the present disclosure, the heat dissipating material (350) may have a viscosity within a predetermined range. Even if an external force is applied to the electronic device (101), the heat dissipating material (350) may not flow with a large displacement in the internal space (331) due to its viscosity. Unlike a liquid, the heat dissipating material (350) has high viscosity and thus does not flow with a large displacement in the internal space (331), and thus may be understood as a gel-like material. As an example, the heat dissipating material may include heat dissipating particles (e.g., Al2O3 and / or AlN), additives (such as a curing agent and a catalyst), silicone resin, silicone oil, and the like.
[0103] According to one embodiment of the present disclosure, the heat dissipation material (350) may include a first portion (351) disposed between the upper surface (341s, 344s) of the shield can (341, 344) and the third surface (321) of the second printed circuit board (320).

The heat dissipation material (350) may be stably disposed between the upper surface (341s, 344s) of the shield can (341, 344) and the third surface (321) of the second printed circuit board (320) by the shield can (341, 344). Accordingly, the heat dissipation material (350) can be stably placed in one area of the internal space (331) through the shield can (341, 344), and the amount of the heat dissipation material (350) placed in the internal space (331) can be minimized and / or reduced.

[0105] According to one embodiment of the present disclosure, the electronic device (101) may include a through hole (313) disposed (e.g., formed through, penetrated) in a first printed circuit board (310). The through hole (313) may penetrate a first surface (311) and a second surface (312) of the first printed circuit board (310). The through hole (313) may be located on an outer side of a shield can (341, 344). The through hole (313) may be disposed adjacent to the shield can (341, 344).

The plurality of mounting components (E3, E4, E5, E6) may be mounted on a third side (321) and / or a fourth side (322) of the second printed circuit board (320). As an example, the plurality of mounting components (E3, E4, E5, E6) may include, but are not limited to, power control components (e.g., Power Management Integrated Circuit), communication components (e.g., Radio Frequency Integrated Circuit or Intermediate Frequency Integrated Circuit), or electrical components such as capacitors.
[0108] According to one embodiment of the present disclosure, the plurality of mounting components (E3, E4, E5, E6) may include a first mounting component (E3). The first mounting component (E3) may be positioned between the upper surface (341s) of the first shield can (341) and the third surface (321) of the second printed circuit board (320). The first mounting component (E3) may be mounted on an area of the third surface (321) facing the upper surface (341s) of the first shield can (341).
[0109] According to one embodiment of the present disclosure, the plurality of mounting components (E3, E4, E5, E6) may include a second mounting component (E4). The second mounting component (E4) may be positioned between the upper surface (344s) of the second shield can (344) and the third surface (321) of the second printed circuit board (320). The second mounting component (E4) may be mounted on an area of the third surface (321) facing the upper surface (344s) of the second shield can (344).
[0110] According to one embodiment of the present disclosure, the plurality of mounting components (E3, E4, E5, E6) may include a third mounting component (E5). The third mounting component (E5) may be mounted on an area of a third surface (321) of a second printed circuit board (320) that does not face the upper surfaces (341s, 344s) of the shield candles (341, 344). The plurality of mounting components (E3, E4, E5, E6) may include a fourth mounting component (E6). The fourth mounting component (E6) may be mounted on an area of a first surface (311) of a first printed circuit board (310) where the shield candles (341, 344) are not arranged.
[0111] FIG. 7 is a drawing for explaining injecting a heat dissipating material (350') into an internal space (331) between a first printed circuit board (310) and a second printed circuit board (320) according to one embodiment of the present disclosure. According to one embodiment of the present disclosure, the heat dissipating material (350') can be injected into the internal space (331) through a through hole (313). The heat dissipating material (350') can be injected into the internal space (331) through an (injector, I). However, the method of placing the heat dissipation material (350') in the internal space (331) is not limited thereto, and in another embodiment, the heat dissipation material (350') may be placed in the internal space (331) by applying the heat dissipation material (350') on the third surface (321) and then covering the first printed circuit board (310) on which the shield can (341, 344) is mounted.
[0112] According to one embodiment of the present disclosure, the injector (I) can be inserted into the internal space (331) by passing through the slit and the through hole (313) of the cap (C) in sequence. The heat dissipation material (350') can be introduced into the internal space (331) through the injector (I). The injected heat dissipation material (350') can spread into the internal space (331) along the third surface (321) of the second printed circuit board (320). As the heat dissipation material (350') spreads into the internal space (331) based on the injector (I), the speed at which it spreads can be reduced by colliding with the shield cans (341, 344), components mounted on the first surface (311) of the first printed circuit board (310), or components mounted on the third surface (321) of the second printed circuit board (320).
[0113] According to one embodiment of the present disclosure, the speed at which the heat dissipation material (350') spreads when passing through a narrow gap (e.g., the second region (331b) of the internal space (331)) between the shield can (341, 344) and the third surface (321) may be smaller than the speed at which the heat dissipation material (350') spreads when passing between the first surface (311) and the third surface (321). Therefore, the rough distribution of the heat dissipation material (350') injected into the internal space (331) can be controlled through the arrangement of the shield cans (341, 344).
[0114] According to one embodiment of the present disclosure, the fact that the heat-dissipating material (350') is injected into the internal space (331) through the through-hole (313) may include a case where the heat-dissipating material (350') is injected into the internal space (331) by directly passing through the through-hole (313). In addition, the fact that the heat-dissipating material (350') is injected into the internal space (331) through the through-hole (313) may include a case where an injector (I) is inserted into the internal space (331) through the through-hole (313), and then the heat-dissipating material (350') is injected into the internal space (331) through the inserted injector (I).
[0115] FIG. 8 is a drawing for explaining the distribution of a heat dissipation material (350) on a first printed circuit board (310) according to one embodiment of the present disclosure. FIG. 9 is a drawing for explaining the distribution of a heat dissipation material (350) on a second printed circuit board (320) according to one embodiment of the present disclosure.
[0116] Referring to FIGS. 8 and 9, according to one embodiment of the present disclosure, an interposer (330) may extend over a first printed circuit board (310). For example, the interposer (330) may extend along an edge (311e) of the first printed circuit board (310). A plurality of vias connected to the interposer (330) may be arranged on the outside of the edge (311b).
[0117] According to various embodiments of the present disclosure, the electronic device (101) may include at least one shield can (341, 344, 347). According to one embodiment of the present disclosure, the electronic device (101) may include a plurality (e.g., three) of shield cans (341, 344, 347), as illustrated in FIG. 8. According to another embodiment of the present disclosure (e.g., see FIG. 17), the electronic device (101) may include one shield can, including a single shield can, unlike that illustrated in FIG. 8.
[0118] According to one embodiment of the present disclosure, a plurality of shield candles (341, 344, 347) may be arranged adjacent to the through hole (313). For example, a distance between the plurality of shield candles (341, 344, 347) and the through hole (313) may be 1 mm to 2 mm. The plurality of shield candles (341, 344, 347) may be arranged along a border of the through hole (313) so as to at least partially surround the through hole (313) (e.g., may be arranged adjacent to at least a portion of an edge / circumference of the through hole (313)).
[0119] According to one embodiment of the present disclosure, the third side (321) of the second printed circuit board (320) may include a first region (321c). The first region (321c) is a region corresponding to the electronic component (E1), and as an example, may include a region overlapping the electronic component (E1) when viewed from above the third side (321). The first region (321c) may include a region facing in the opposite direction of a region of the fourth side (322) on which the electronic component (E1) is mounted.
[0120] According to one embodiment of the present disclosure, the third side (321) of the second printed circuit board (320) may include a core region (B1, B2). The core region (B1, B2) is a region corresponding to a region with a large amount of heat generation in the electronic component (E1), and may be, for example, a region corresponding to a processing core of a processor (e.g., processor (120) of FIG. 1).
[0121] According to one embodiment of the present disclosure, the third surface (321) of the second printed circuit board (320) may include a third region (313a). The third region (313a) corresponds to the through hole (313), and as an example, may include a region overlapping the through hole (313) when viewed from above the third surface (321). It can be understood that the heat dissipation material (350) spreads radially based on the third region (313a) corresponding to the through hole (313). The first region (321c), the core regions (B1, B2), and the third region (313a) will be described in detail with reference to FIGS. 9 and 10 .
[0122] FIG. 10 is a drawing for explaining a plurality of areas projected onto a second printed circuit board according to one embodiment of the present disclosure.
[0123] Referring to FIGS. 9 and 10 , according to one embodiment of the present disclosure, a third surface (321) of a second printed circuit board (320) may include a second region (341a, 344a) (e.g., a plurality of second regions) facing a top surface (341s, 344s of FIG. 8) of a shield can (341, 344). That is, the second region (341a) (among the plurality of second regions) may correspond to a region facing the shield can (341) (top surface (341s)), and the second region (344a) may correspond to a region facing the shield can (344) (top surface (344s)). The second region (341a, 344a) may overlap at least partially with the first region (321c). The second region (341a, 344a) may include an area overlapping the shield can (341, 344) when viewed from above the third surface (321).
[0124] According to one embodiment of the present disclosure, the third side (321) of the second printed circuit board (320) may include a fourth side (321i) located inside the first side (321c). The fourth side (321i) may not overlap with the second sides (341a, 344a). The fourth side (321i) may be an area facing an area of the first side (311, see FIG. 8) of the first printed circuit board (310) where the shield can (341, 344) is not disposed. The fourth side (321i) may surround the third side (313a) together with the second side (341a, 344a). The fourth side (321i) may extend from one side of the third side (313a) toward the border of the first side (321c).
[0125] According to one embodiment of the present disclosure, the third region (313a) may be located on the inner side of the first region (321c). When viewed from above on the third side (321) of the second printed circuit board (320), the through hole (313) may be covered by the electronic component (E1). Accordingly, the heat dissipation material (350) injected into the internal space (331) through the through hole (313) may move to the third side (321) of the second printed circuit board (320) and spread in the radial direction (see FIGS. 8 and 9) based on the third region (313a).
[0126] According to one embodiment of the present disclosure, the third region (313a) may be spaced apart from the central portion (321t) of the first region (321c). For example, the third region (313a) may be positioned closer to one side of the edge than the center of the first region (321c). In this case, the heat dissipation material (350) injected through the through hole (313) may not be evenly spread throughout the first region (321c). In addition, a large amount of the heat dissipation material (350) needs to be injected in order to contact the entire first region (321c) or the region spaced apart from the third region (313a) (e.g., the core region (B1, B2)).
[0127] According to one embodiment of the present disclosure, the heat dissipation material (350) injected through the through hole (313) can spread radially with respect to the third region (313a). The heat dissipation material (350) that spreads radially with respect to the third region (313a) can spread along the second region (341a, 344a) and the fourth region (321i). The speed at which the heat dissipation material (350) spreads along the second region (341a, 344a) can be lower than the speed at which it spreads along the fourth region (321i). Therefore, the heat dissipation material (350) can spread farther from the third region (313a) when it spreads along the fourth region (321i) compared to when it spreads along the second region (341a, 344a). Additionally, the heat dissipation material (350) can be controlled to spread to areas requiring heat dissipation (e.g., core areas (B1, B2)). Accordingly, the amount of heat dissipation material (350) used to increase the area covering the third area (313a) and the first area (321c) can be minimized and / or reduced.
[0128] According to one embodiment of the present disclosure, the second region (341a, 344a) may include edges (341b, 344b, 344c) corresponding to side surfaces of the shield cans (341, 344). The first edges (341b) and the second edges (344b) that are adjacent to each other may extend approximately parallel to each other. In an embodiment, the first edges (341b) and the second edges (344b) may correspond to adjacent side surfaces of the respective shield cans (341, 344) that are adjacent to each other. The first edges (341b) and the second edges (344b) may be spaced apart from each other by a first distance (d1).
[0129] According to one embodiment of the present disclosure, a third region (313a) may be arranged between a first edge (341b) and a third edge (344c). The first edge (341b) and the third edge (344c) may extend approximately parallel to each other. The first edge (341b) and the third edge (344c) may be spaced apart from each other by a second distance (d2). The second distance (d2) may be greater than the first interval (d1).
[0130] According to one embodiment of the present disclosure, a third region (313a) corresponding to a through hole (313) may have a predetermined diameter (D). The diameter (D) of the third region (313a) may be greater than the first distance (d1). The diameter (D) of the third region (313a) may be smaller than the second distance (d2).
[0131] According to one embodiment of the present disclosure, one end of the fourth region (321i) adjacent to the third region (313a) may have a predetermined width (d3). This width may be greater than the gap (d1) between two adjacent shield candles (341, 344) among the plurality of shield candles (341, 344, 347). The width (d3) of one end of the fourth region (321i) may be equal to or greater than the diameter (D) of the third region (313a).
[0132] FIG. 11 is a drawing for explaining the arrangement of a plurality of shield candles (341, 344, 347) and a through hole (313) according to one embodiment of the present disclosure.
[0133] Referring to FIG. 11, according to one embodiment of the present disclosure, a plurality of shield candles (341, 344, 347) may be arranged to at least partially surround the through hole (313). The plurality of shield candles (341, 344, 347) may be positioned adjacent to each other.

The number and shape of the shield cans are not limited to the various embodiments of the present disclosure, and may include a case where at least some (e.g., the first shield can (341) and the second shield can (344)) of the plurality of shield candles (341, 344, 347) illustrated in FIG. 11 are formed integrally.
[0134] According to one embodiment of the present disclosure, the first shield can (341) may include a base portion (341w) that contacts a conductive pad (314) disposed on a first surface (311) of the first printed circuit board (310). Solder cream may be applied between the conductive pad (314) and the base portion (341w). The first shield can (341) may include a plurality of base portions (341w), and a recess (341g) may be formed between the base portions (341w). The interior and the exterior of the first shield can (341) may be spatially connected through the recesses (341g).
[0135] According to one embodiment of the present disclosure, the first shield can (341) may include a first side portion (3411) that partially surrounds the through hole (313). The first shield can (341) may include a second side portion (3412) that extends from the first side portion (3411) and is adjacent to the second shield can (344). The first shield can (341) may include a third side portion (3413) that extends from the first side portion (3411) and is located further from the through hole (313) than the first side portion (3411).
[0136] According to one embodiment of the present disclosure, the second shield can (344) may include a first side portion (3441) that partially surrounds the through hole (313). The first side portion (3441) may be partially curved along the through hole (313). The second shield can (344) may include a second side portion (3442) that extends from the first side portion (3441) and is adjacent to the first shield can (341). The second shield can (344) may include a third side portion (3443) that extends from the first side portion (3441) and is located further from the through hole (313) than the first side portion (3441).
[0137] According to one embodiment of the present disclosure, the third shield can (347) may include a first side portion (3471) adjacent to a third side portion (3443) of the second shield can (344). The third shield can (347) may include a second side portion (3472) extending away from the through hole (313) from the first side portion (3441).
[0138] According to one embodiment of the present disclosure, the second side portion (3412) of the first shield can (341) may extend along the second side portion (3442) of the second shield can (344). The first side portion (3411) of the first shield can (341) and the first side portion (3441) of the second shield can (344) may extend to surround the through hole (313). The distance (G3) between the second side portion (3412) of the first shield can (341) and the second side portion (3442) of the second shield can (344) may be smaller than the distance (G31) between the first side portion (3411) of the first shield can (341) and the first side portion (3441) of the second shield can (344).
[0139] According to one embodiment of the present disclosure, the third side portion (3413) of the first shield can (341) may extend along the second side portion (3472) of the third shield can (347). The third side portion (3413) of the first shield can (341) and the second side portion (3472) of the third shield can (347) may be spaced apart from each other by a predetermined distance (G5). The distance (G5) between the third side portion (3413) of the first shield can (341) and the second side portion (3472) of the third shield can (347) may be greater than the distance (G31) between the first side portion (3411) of the first shield can (341) and the first side portion (3441) of the second shield can (344). Therefore, the heat dissipation material may flow smoothly.
[0140] FIG. 12 illustrates a state in which the shield candles (341, 344, 347) are removed from FIG. 11, according to one embodiment of the present disclosure.
[0141] According to one embodiment of the present disclosure, an electronic device (101) may include a plurality of conductive pads (314, 315, 316). The conductive pads (314, 315, 316) may be disposed on a first surface (311) of a first printed circuit board (310). A first shield can (341) may be disposed on the first conductive pad (314). A second shield can (344) may be disposed on the second conductive pad (315). A third shield can (347) may be disposed on the third conductive pad (316).

The predetermined first loop formed by the plurality of first conductive pads (314) may correspond to an edge of a first shield can (341). The first shield can (341) may be disposed on the plurality of first conductive pads (314).
[0143] According to one embodiment of the present disclosure, the electronic device (101) may include a plurality of second conductive pads (315). The plurality of second conductive pads (315) may be arranged to form a predetermined second loop. The predetermined second loop formed by the plurality of second conductive pads (315) may correspond to an edge of a second shield can (344). The second shield can (344) may be disposed on the plurality of second conductive pads (315).
[0144] According to one embodiment of the present disclosure, the electronic device (101) may include a plurality of third conductive pads (316). The plurality of third conductive pads (316) may be arranged to form a predetermined third loop. The predetermined third loop formed by the plurality of third conductive pads (316) may correspond to an edge of a third shield can (347). The third shield can (347) may be disposed on the plurality of third conductive pads (316).
[0145] According to one embodiment of the present disclosure, the number of conductive pads (314, 315, 316) is not limited to the embodiment illustrated in FIG. 12. According to various embodiments of the present disclosure, the plurality of first conductive pads (314), the plurality of second conductive pads (315), or the plurality of third conductive pads (316) may be formed of at least one (e.g., one or two) conductive pad, unlike as illustrated in FIG. 12.
[0146] According to one embodiment of the present disclosure, a portion (314a) of the first conductive pad (314) and a portion (315a) of the second conductive pad (315) may be extended to partially surround the through hole (313). A heat dissipation material (350) introduced into the internal space (331) through the through hole (313) may spread along the outer surfaces of the plurality of shield candles (341, 344, 347).
[0147] According to one embodiment of the present disclosure, both ends (314b, 314c) of the first conductive pad (314) may be spaced apart from the center (P) of the through hole (313). Both ends (315b, 315c) of the second conductive pad (315) may be spaced apart from the center (P) of the through hole (313). Both ends (316b, 316c) of the third conductive pad (316) may be spaced apart from the center (P) of the through hole (313). Recesses (341g, see FIG. 11) of shield cans (341, 344, 347) may be positioned at both ends (314b, 314c, 315b, 315c, 316b, 316c) of the conductive pads (314, 315, 316).

[0149] FIG. 13 is a graph showing the temperature of an electronic component (E1) according to the amount of injected heat dissipation material (350) according to one embodiment of the present disclosure. The temperature of the electronic component (E1) can be understood as the temperature of the electronic component (E1) measured based on the time when the electronic component (E1) exhibits maximum performance. Y represents the temperature when the shield cans (341, 344, 347) are not placed in the internal space (331), unlike one embodiment of the present disclosure, and X represents the temperature when the shield cans (341, 344, 347) are placed in the internal space (331), as in one embodiment of the present disclosure. As an example, the temperature of the electronic component (E1) can be calculated through values measured by a plurality of thermometers (not shown) included in the electronic component (E1).
[0150] Referring to FIG. 13, unlike one embodiment of the present disclosure, when the shield can (341, 344, 347) is not placed in the internal space (331) (Y), the temperature of the electronic component (E1) becomes an appropriate temperature (e.g., 62 degrees Celsius) when 2 g of heat dissipation material (350) is injected, but like one embodiment of the present disclosure, when the shield can (341, 344, 347) is not placed in the internal space (331) (X), the temperature of the electronic component (E1) can be confirmed to be at the appropriate temperature even when only 1.4 g of heat dissipation material (350) is injected.
[0151] According to one embodiment of the present disclosure, by arranging the shield cans (341, 344, 347), the heat dissipation material (350) is stably arranged in an area (e.g., the first area (321c)) of the third surface (321) that can effectively dissipate heat from the electronic component (E1), thereby ensuring the heat dissipation performance of the electronic component (E1) with only a smaller amount of the heat dissipation material (350).
[0152] FIG. 14 illustrates a location of a heat dissipating material (1350) on a first printed circuit board (310), according to one embodiment of the present disclosure. FIG. 15 illustrates a location of a heat dissipating material (1350) on a second printed circuit board (320), according to one embodiment of the present disclosure. FIG. 16 illustrates a plurality of regions projected onto a second printed circuit board, according to one embodiment of the present disclosure.
[0153] The description of the components described with reference to FIGS. 2 to 13 (e.g., heat dissipation material (350), multiple shield candles (341, 344, 347), first region (321c), second region (341a, 344a, 347a)) can be substantially identically applied to the components of the same name illustrated in FIGS. 14 to 16 (e.g., heat dissipation material (1350), multiple shield candles (1341, 1344, 1347), first region (321c'), second region (1341a, 1344a, 1347a)) to the extent that they are not arranged with each other.
[0154] Referring to FIGS. 14 to 16, a plurality of shield candles (1341, 1344, 1347) can surround a through hole (313). A heat dissipation material (1350) injected into the internal space (331) through the through hole (313) can spread radially with respect to the through hole (313). The injected heat dissipation material (1350) can be placed between the plurality of shield candles (1341, 1344, 1347) and the third surface (321) of the second printed circuit board (320).
[0155] According to one embodiment of the present disclosure, a third surface (321) of a second printed circuit board (320) may include a first region (321c') corresponding to an electronic component (E1).

When viewed from above the third surface (321), the third region (1313a) may be located inside the first region (321c'). As an example, the third region (1313a) corresponding to the through hole (1313) may be located in the central portion of the first region (321c') (e.g., the central portion (321t) of FIG. 10).
[0157] According to one embodiment of the present disclosure, second regions (1341a, 1344a, 1347a) corresponding to a plurality of shield candles (1341, 1344, 1347) can surround a third region (313a). A heat dissipation material (350) introduced into the internal space (331) through the through hole (313) can spread along the second regions (1341a, 1344a, 1347a) of the third surface (321) and can be stably positioned between the plurality of shield candles (1341, 1344, 1347) and the third surface (321).

[0159] The description of the components described with reference to FIGS. 2 to 13 (e.g., heat dissipation material (350), shield cans (341, 344, 347), second region (341a, 344a, 347a), third region (313a), through hole (313)) can be substantially identically applied to the components of the same name shown in FIGS. 17 and 18 (e.g., heat dissipation material (1350), multiple shield cans (1341, 1344, 1347), first region (321c'), second region (2341a), third region (2313a), through hole (2313)) to the extent that they are not arranged with each other.
[0160] Referring to FIGS. 17 and 18, according to one embodiment of the present disclosure, a third surface (321) of a second printed circuit board (320) may include a second region (2341a) corresponding to a shield can (2341). The second region (2341a) may include a region of the third surface (321) facing a top surface (2341s) of the shield can (2341). The second region (2341a) may be located outside the first region (321c). The second region (2341a) may be spaced apart from the first region (321c).
[0161] According to one embodiment of the present disclosure, the third surface (321) of the second printed circuit board (320) may include a third region (2313a) corresponding to the through hole (2313). The third region (2313a) may face the through hole (2313). The third region (2313a) may be located between the second region (2341a) and the first region (321c).
[0162] According to one embodiment of the present disclosure, a heat dissipation material (2350) injected into the internal space (331) through a through hole (2313) may include a first portion (2351) between the shield can (2341) and the second region (2341a). The heat dissipation material (2350) may include a second portion (2352) between the first surface (311) of the first printed circuit board (310) and the first region (321c) of the third surface (321).
[0163] According to one embodiment of the present disclosure, the rate at which the heat dissipation material (2350) spreads toward the second region (2341a) with respect to the through hole (2313) may be lower than the rate at which it spreads toward the first region (321c). Accordingly, a greater amount of the heat dissipation material (2350) may spread from the through hole (2313) toward the opposite side of the shield can (2341).
[0164] FIG. 19 is a cross-sectional view of a portion of an electronic device (101) showing a plurality of shield candles (3341, 3344) according to one embodiment of the present disclosure.
[0165] The description of components (e.g., heat dissipation material (350), shield cans (341, 344)) described with reference to FIGS. 2 to 13 can be substantially identically applied to components of the same name (e.g., heat dissipation material (3350), shield cans (1341, 1344)) illustrated in FIG. 19, to the extent that they are not arranged with each other.
[0166] According to one embodiment of the present disclosure, the electronic device (101) may include a plurality of shield candles (3341, 3344). The plurality of shield candles (3341, 3344) may at least partially surround the through hole (313).

[0167] According to one embodiment of the present disclosure, when viewed from above on the fourth surface (322), the through hole (313) may be covered by the electronic component (E1). When viewed from above on the fourth surface (322), the through hole (313) may be spaced apart from the center of the electronic component (E1) (e.g., the center portion (321t) of FIG. 10).
[0168] The heights protruding from the first surface (311) of the first printed circuit board (310) may be different from each other. For example, the heights of the first shield can (3341) and the second shield can (3344) extending from the first surface (311) to the internal space (331) may be different from each other. For example, the gap (G22) between the first shield can (3341) (e.g., the first shield can (3341) having a smaller height than the second shield can (3344)) and the first surface (311) may be lower than the gap (G21) between the second shield can (3344) and the first surface (311).
[0169] According to one embodiment of the present disclosure, when viewed from above on the fourth side (322), the first shield can (3341) may be positioned closer to the center of the electronic component (E1) than the second shield can (3344). As an example, when viewed from above on the fourth side (322), an overlapping area between the first shield can (3341) and the electronic component (E1) may be larger than an overlapping area between the second shield can (3344) and the electronic component (E1).

FIG. 22 illustrates a second printed circuit board (4320) and an interposer (4330) according to one embodiment of the present disclosure.
[0171] The description of the components described with reference to FIGS. 2 to 13 (e.g., heat dissipation material (350), first printed circuit board (310), second printed circuit board (320), interposer (330), through hole (313)) can be substantially identically applied to the components of the same name illustrated in FIGS. 20 to 22 (e.g., heat dissipation material (4350), first printed circuit board (4310), second printed circuit board (4320), interposer (4330), through hole (4313)) to the extent that they are not arranged with each other.
[0172] Referring to FIGS. 20 to 22, according to one embodiment of the present disclosure, an electronic device (101) may include a first printed circuit board (4310) including a first side (4311) and a second side (4312) facing in an opposite direction to the first side (4311). The first side (4311) of the first printed circuit board (4310) may be partitioned into a first portion (4311a) and a second portion (4311b) based on a second interposer (4332). A through hole (4313) may be formed in the second portion (4311b) of the first side (4311).
[0173] According to one embodiment of the present disclosure, the electronic device (101) may include a third side (4321) facing a first side (4311) of a first printed circuit board (4310) and a fourth side (4322) facing in an opposite direction of the third side (4321). The second printed circuit board (4320) may be spaced apart from the first printed circuit board (4310). The third side (4321) of the second printed circuit board (4320) may be partitioned into a first portion (4321a) and a second portion (4321b) based on a second interposer (4332).
[0174] According to one embodiment of the present disclosure, a second portion (4321b) of a third surface (4321) of a second printed circuit board (4320) may include an electronic component area (4321c). The electronic component area (4321c) is an area corresponding to the electronic component (E1), and as an example, may include an area overlapping the electronic component (E1) when viewed from above the third surface (4321). The electronic component area (4321c) may include a portion of the third surface (4321) that is opposite to an area of the fourth surface (4322) on which the electronic component (E1) is mounted.
[0175] According to one embodiment of the present disclosure, a second portion (4321b) of a third surface (4321) of a second printed circuit board (4320) may include a through-hole region (4313a). The through-hole region (4313a) is a region corresponding to the through-hole (4313), and as an example, may include a region overlapping the through-hole (4313) when viewed from above the third surface (4321). The through-hole region (4313a) may be located inside the electronic component region (4321c).
[0176] According to one embodiment of the present disclosure, an electronic device (101) may include an interposer (4330). The interposer (4330) may be disposed between a first printed circuit board (4310) and a second printed circuit board (4320). In one embodiment, the interposer (4330) may include a plurality of interposer portions. The interposer (4330) may include a first interposer (4331) extending along an edge (4321e) of a third side (4321) of the second printed circuit board (4320) to form an inside space (4331a, 4331b). The interposer (4330) may include a second interposer (4332) disposed in the inside space (4331a, 4331b).
[0177] According to one embodiment of the present disclosure, the second interposer (4332) may be spaced inwardly from the first interposer (4331) (e.g., positioned on the inner side of an edge (4321e) of the third side (4321) within the internal space (4331). That is, in one embodiment, when the first interposer (4331) extends along the edge of the third side (4321) of the second printed circuit board (4320), the second interposer (4332) may be positioned on the inner side of the first interposer (4331). The second interposer (4332) may be connected to the first interposer (4331). The second interposer (4332) may be connected to the first interposer (4331), and in another embodiment, the second interposer (4332) may be positioned adjacent to the first interposer (4331).
[0178] According to one embodiment of the present disclosure, the second interposer (4332) may extend across the internal spaces (4331a, 4331b). In one embodiment, the second interposer (4332) may extend across (e.g., divide) the internal spaces (4331a, 4331b). That is, in one embodiment, the internal spaces (4331a, 4331b) may be located on each side of the second interposer (4332). The second interposer (4332) may extend along an edge of an electronic component (E1) mounted on a fourth surface (4322) of a second printed circuit board (4320). When viewed from above the fourth surface (4322), the second interposer (4332) may partially overlap the electronic component (E1) or may be located outside the electronic component (E1). The internal space (4331a, 4331b) can be partitioned into a first mounting space (4331a) and a second mounting space (4331b) by the second interposer (4332). That is, the mounting space (e.g., the mounting space (4331a, 4331b)) can be considered as a space (e.g., the internal space (4331a, 4331b)) where various components are placed.
[0179] According to one embodiment of the present disclosure, a heat dissipation material (4350) can be injected into the second mounting space (4331b) through the through hole (4313). Since the heat dissipation material (4350) is not introduced into the first mounting space (4331a) by the second interposer (4332), the injection amount of the heat dissipation material (4350) for heat dissipation of the electronic component (E1) can be minimized and / or reduced.
[0180] According to one embodiment of the present disclosure, a first printed circuit board (4310) may include an interposer mounting portion (4311e, 4311f). A first interposer (4331) may be mounted on the first interposer mounting portion (4311e). The first interposer mounting portion (4311e) may form an edge (4311e) of the first printed circuit board (4310). A second interposer (4332) may be mounted on the second interposer mounting portion (4311f). The first surface (4311) may be partitioned into a first region (4311c) and a second region (4311d) by the second interposer mounting portion (4311f).
[0181] FIG. 23 is a cross-sectional view of a portion of an electronic device (101) according to an embodiment of the present disclosure. FIG. 24 illustrates views of electronic components (E1, E2) and a solid heat transfer member (430) disposed on the electronic components (E1, E2) from two directions according to an embodiment of the present disclosure. FIG. 25 illustrates views of a gel-like heat transfer member (430) compressed by a conductive layer (440, see FIG. 23) and electronic components (E1, E2) from two directions according to an embodiment of the present disclosure.
[0182] Referring to FIGS. 23 to 25, an electronic device (101) according to an embodiment of the present disclosure may include a second electronic component (E2) disposed on a first electronic component (E1). The second electronic component (E2) may be mounted on the first electronic component (E1). As an example, the first electronic component (E1) may include a processor (e.g., the processor (120) of FIG. 1), and the second electronic component (E2) may be a memory (e.g., the memory (130) of FIG. 1) mounted on the first electronic component (E1) via solder balls and operatively connected to the first electronic component (E1).
[0183] According to one embodiment of the present disclosure, an electronic device (101) may include a substrate assembly (400). The description of the substrate assembly (240a) described with reference to FIG. 4 may be substantially identically applied to the substrate assembly (400) illustrated in FIG. 23 to the extent that they are not mutually disposed. The substrate assembly (400) may include a heat transfer member (430, see FIG. 25). The heat transfer member (430) may contact the first electronic component (E1) and the second electronic component (E2). Heat generated in the first electronic component (E1) and the second electronic component (E2) may be released to the outside of the electronic device (101) by the heat transfer member (430).
[0184] According to one embodiment of the present disclosure, a heat transfer member (430) may include a first portion (433) that contacts a second electronic component (E2). The first portion (433) of the heat transfer member (430) may be disposed between the second electronic component (E2) and the first conductive sheet (441). Accordingly, heat of the second electronic component (E2) may be spread to the first conductive sheet (441) through the first portion (433). In addition, heat of the first electronic component (E1) may be spread to the first conductive sheet (441) through the second electronic component (E2) and the first portion (433).
[0185] According to one embodiment of the present disclosure, the heat transfer member (430) may include a second portion (431, 432) that contacts the first electronic component (E1). Accordingly, heat of the first electronic component (E1) may spread from the first surface (E11) to the second portion (431, 432) of the heat transfer member (430). The second portion (431, 432) of the heat transfer member (430) may extend from the first portion (433) toward the first electronic component (E1). As an example, the second portion (431, 432) may protrude from the edge of the first portion (433) toward the first electronic component (E1).
[0186] According to one embodiment of the present disclosure, the heat transfer member (430) can at least partially cover the second electronic component (E2). The second portion (431, 432) of the heat transfer member (430) can cover at least a portion of the second surface (E22) of the second electronic component (E2). As an example, the first surface (E21) of the second electronic component (E2) can be a top surface, and the second surface (E22) can be a side surface.
[0187] According to one embodiment of the present disclosure, the electronic device (101) may include a shield can (420) disposed on a second printed circuit board (320). The shield can (420) may surround a first electronic component (E1) and a second electronic component (E2). The shield can (420) may be connected to a ground layer (not shown) through the printed circuit board (320).
[0188] According to one embodiment of the present disclosure, the electronic device (101) may include a conductive layer (440) disposed on a shield can (420). As an example, the conductive layer (440) may be in contact with the shield can (420) or may be bonded to the shield can (420) by a conductive adhesive. The conductive layer (440) and the shield can (420) may define a space that can minimize the influence of an external magnetic field. The shield can (420) and the conductive layer (440) may surround the first electronic component (E1), the second electronic component (E2), and the heat transfer member (430). Therefore, the influence of the external magnetic field on the first electronic component (E1) and the second electronic component (E2) may be minimized and / or reduced.
[0189] According to one embodiment of the present disclosure, the conductive layer (440) may include a first conductive sheet (441) disposed on a heat transfer member (430). The first conductive sheet (441) may cover one surface of the heat transfer member (430). For example, the first conductive sheet (441) may contact the one surface of the heat transfer member (430). Accordingly, heat may spread from the heat transfer member (430) to the first conductive sheet (441). As an example, the first conductive sheet (441) may be a copper thin film. The first conductive sheet (441) may contact the metal cover (M). The first conductive sheet (441) may be disposed between the heat transfer member (430) and the metal cover (M). Accordingly, heat may spread from the first conductive sheet (441) to the metal cover (M).
[0190] According to one embodiment of the present disclosure, the conductive layer (440) may be supported by the shield can (420). The conductive layer (440) may include a second conductive sheet (442) interposed between the first conductive sheet (441) and the shield can (420). The second conductive sheet (442) may surround a portion of the heat transfer member (430). For example, the second conductive sheet (442) may contact a side surface of the heat transfer member (430). Accordingly, heat may spread from the heat transfer member (430) to the second conductive sheet (442). As an example, the second conductive sheet (442) may be a metal thin film having a lower thermal conductivity than the first conductive sheet (441).
[0191] According to one embodiment of the present disclosure, the shield can (420) and the first conductive sheet (441) can be electrically connected through the second conductive sheet (442). Accordingly, the first electronic component (E1) and the second electronic component (E2) can minimize the influence of an external magnetic field through the shield can (420), the second conductive sheet (442), and the first conductive sheet (441).
[0192] According to one embodiment of the present disclosure, a portion of the heat generated from the first electronic component (E1) may be transferred to the heat dissipation material (350) through the second printed circuit board (320). A portion of the heat generated from the first electronic component (E1) may be transferred to the heat dissipation member (V) through the heat transfer member (430). The first electronic component (E1) may be positioned between the first shield can (341) and the heat dissipation member (V). When viewed from above the fourth surface (322), the first shield can (341) may overlap with the first electronic component (E1) or may be covered by the first electronic component (E1). For example, the first shield can (341) and the heat dissipation member (V) may be positioned on opposite sides with respect to the first electronic component (E1).
[0193] According to one embodiment of the present disclosure, the internal space (343) of the first shield can (341) can function as an insulating layer during the process of transferring heat generated from the first electronic component (E1). The heat generated from the first electronic component (E1) can be absorbed by the heat dissipation material (350), but due to the low thermal conductivity of air, the amount transferred to the surface of the electronic device (101) (e.g., the rear surface (210B) of FIG. 3) through the air layer can be limited. Accordingly, the surface of the electronic device (101) (e.g., the rear surface (210B) of FIG. 3) can be prevented from being locally overheated.
[0194] According to one embodiment of the present disclosure, a heat dispersion member (V) may be positioned between a first surface (210A, see FIG. 4) of an electronic device (101) and a first electronic component (E1). Accordingly, heat generated from the first electronic component (E1) may be transferred to the first surface (210A) through the heat dispersion member (V). A first shield can (341) may be positioned between a second surface (210B, see FIG. 4) of an electronic device (101) and the first electronic component (E1). Accordingly, heat generated from the first electronic component (E1) may be transferred to the second surface (210B, see FIG. 4) through the first shield can (341).
[0195] According to one embodiment of the present disclosure, the heat transfer member (430) may include a phase change material. As an example, the phase change material may include a paraffin-based material, which is a temperature-sensitive material. The heat transfer member (430) may be in a solid state at room temperature. The heat transfer member (430) may be in a gel state at least partially above a predetermined temperature. As an example, the predetermined temperature may be a temperature of approximately 45 degrees Celsius to 65 degrees Celsius.
[0196] According to one embodiment of the present disclosure, the heat transfer member (430) may be in a solid state at room temperature (Tr). For example, the room temperature (Tr) may be a temperature of 15 degrees Celsius to 25 degrees Celsius. When the heat transfer member (430) is in a solid state, the transport, placement, and assembly of the heat transfer member (430) may be easier compared to when the heat transfer member (430) is in a liquid or gel state. In addition, when the heat transfer member (430) is in a solid state, it has a certain level of rigidity, so that defects such as dents or compression of the heat transfer member (430) that may occur during the assembly and transport process can be reduced. Therefore, it is possible to prevent dents or compression from occurring and preventing the shape of the heat transfer member (430) from being restored, and thus, the dispersion of the heat dissipation performance of the heat transfer member (430) can be minimized.
[0197] According to one embodiment of the present disclosure, when the heat transfer member (430) is solid, a material (e.g., a phase change material) included in the heat transfer member (430) does not permeate into the gap of the shielding structure (e.g., the conductive layer (440) and the shield can (420) of FIG. 3) around the heat transfer member (430), and thus may not impair the shielding performance of the shielding structure. Even if the heat transfer member (430) becomes a gel phase after the electronic device (101) is operated, the heat transfer member (430) becomes a gel phase when the phase transition temperature (Tc) is reached after the electronic device (101) is operated, and does not contain silicone resin or oil that causes bleeding, and thus may not impair the shielding performance of the surrounding shielding structure (e.g., the conductive layer (440) and the shield can (420) of FIG. 3).
[0198] According to one embodiment of the present disclosure, the heat transfer member (430) may include a matrix material configured to maintain the heat transfer member (430) in a gel state at a temperature higher than the phase transition temperature (Tc). The matrix material functions as a frame of the heat transfer member (430), thereby substantially maintaining the shape of the heat transfer member (430) even when the temperature of the heat transfer member (430) rises to a temperature higher than the phase transition temperature (Tc). As an example, the matrix material may be a rubber-based material. The matrix material is not limited to a rubber-based material, and may be replaced with a material that can function as a frame.
[0199] According to one embodiment of the present disclosure, the gel phase in which the heat dissipation material (350) and the heat transfer member (430) are transferred have the same name, but may have different properties depending on their composition or composition ratio. For example, the gel state of the heat dissipation material (350) injected into the internal space (331) may not maintain its shape and may flow in the internal space (331) compared to the gel state of the heat transfer member (430). In contrast, the gel state of the heat transfer member (430) may be understood as a gel state in which the shape is maintained by the matrix material and does not flow, as an example, compared to the gel state of the heat dissipation material (350).
[0200] According to one embodiment of the present disclosure, the heat transfer member (430) may include heat dissipating particles. As an example, the heat dissipating particles may be aluminum oxide (Al2O3) or aluminum nitride (AlN). As another example, the heat dissipating particles may be carbon fiber, graphene, boron nitride (BN), silicon carbide (SiC), magnesium oxide (MgO), or manganese oxide (ZnO).
[0201] According to one embodiment of the present disclosure, the heat transfer member (430) may include heat-radiating particles, a phase change material, and a matrix material. As an example, the heat transfer member (430) may include about 75 to 90% heat-radiating particles, about 5 to 15% matrix material, and about 5 to 15% phase change material. The composition ratio of the heat-radiating particles, the matrix material, and the phase change material included in the heat transfer member (430) is not limited to the above examples.
[0202] According to one embodiment of the present disclosure, as the first electronic component (E1) and / or the second electronic component (E2) operates, the temperature of the heat transfer member (430) may increase due to heat generation of the first electronic component (E1) and / or the second electronic component (E2). When the temperature of the heat transfer member (430) increases after the first electronic component (E1) and / or the second electronic component (E2) operates, the heat transfer member (430) may at least partially change into a gel state.
[0203] According to one embodiment of the present disclosure, a first portion (433) of a solid heat transfer member (430) before being changed into a gel state may have a first height (h1). A plurality of second portions (431, 432) may have a first thickness (t1) and a second thickness (t2), respectively. A distance between an inner surface (430i) and an outer surface (430o) of the plurality of second portions (431, 432) may be a first thickness (t1) and a second thickness (t2), respectively.
[0204] According to one embodiment of the present disclosure, the inner surface (430i) of the second portion (431, 432) of the solid heat transfer member (430) before changing into a gel state can be spaced apart from the second surface (E22) of the second electronic component (E2) for easy coupling of the heat transfer member (430). Accordingly, the heat transfer member (430) can be easily assembled to the second electronic component (E2).
[0205] According to one embodiment of the present disclosure, after being changed into a gel state, the first portion (433) of the heat transfer member (430) compressed by the conductive layer (440) may have a second height (h2) smaller than the first height (h1). The plurality of second portions (431, 432) of the heat transfer member (430) compressed by the conductive layer (440) may have a third thickness (t3) larger than the first thickness (t1) and a fourth thickness (t4) larger than the second thickness (t2), respectively. The third thickness (t3) and the fourth thickness (t4) may be the largest thicknesses of each of the plurality of second portions (431, 432).
[0206] According to one embodiment of the present disclosure, the heat transfer member (430) may be compressed by the conductive layer (440) after changing into a gel state. When compressed by the conductive layer (440), the height of the first portion (433) of the heat transfer member (430) may decrease from the first height (h1) to the second height (h2). The difference between the first height (h1) and the second height (h2) may be due to an assembly tolerance that may occur during the manufacturing process of the substrate assembly (400). For example, tolerances such as an assembly tolerance that may occur during the process of assembling components (410, 420, 430, 440, E1, E2) of the substrate assembly (400), a component height tolerance of the second printed circuit board (320) and electronic components (E1, E2), etc. may occur.
[0207] According to one embodiment of the present disclosure, the gel-phase heat transfer member (430) can have a higher compressibility compared to the solid-phase heat transfer member (430). For example, the gel-phase heat transfer member (430) can have a compressibility of about 25 to 40%, and more specifically, can have a compressibility of about 35 to 40%. Since the heat transfer member (430) of the present disclosure has a higher compressibility in the gel phase compared to the solid-phase case, the above tolerances can be filled by the heat transfer member (430). For example, when the heat transfer member (430) becomes at least partially in the gel phase when the temperature is higher than the limit temperature (Tc), the heat transfer member (430) can be configured to have a compressibility of about 35 to 40%, and the second height (h2) can be a value that is reduced by about 35 to 40% from the first height (h1).
[0208] According to one embodiment of the present disclosure, as the height of the first portion (433) of the heat transfer member (430) decreases, the thickness of the second portion (431, 432) of the heat transfer member (430) may increase. As the thickness of the second portion (431, 432) of the heat transfer member (430) increases, the second portion (431, 432) may be brought into close contact with the second surface (E22) of the second electronic component (E2). As the thickness of the second portion (431, 432) of the heat transfer member (430) increases, the inner surface (430i) of the second portion (431, 432) may be brought into close contact with the second surface (E22) of the second electronic component (E2). As the thickness of the second part (431, 432) of the heat transfer member (430) increases, the second part (431, 432) can be brought into close contact with the shield can (420, see FIG. 3).
[0209] According to one embodiment of the present disclosure, a first surface (E11) of a surface (E11, E12) of a first electronic component (E1) may include a first area (E111) in which a second electronic component (E2) is disposed. Heat may diffuse from the first electronic component (E1) to the second electronic component (E2) through the first area (E111).
[0210] According to one embodiment of the present disclosure, a first surface (E11) of a surface (E11, E12) of a first electronic component (E1) may include a second region (E112) that contacts a second portion (431, 432) of the heat transfer member (430). The second region (E112) may at least partially surround the first region (E111). Heat may diffuse from the first electronic component (E1) to the second portion (431, 432) of the heat transfer member (430) through the second region (E112).
[0211] According to one embodiment of the present disclosure, the first electronic component (E1) may include a heat generating block (B). The heat generating block (B) may be positioned below the first surface (E11) and may overlap with the second region (E112). The heat generating block (B) may be positioned below the boundary between the first region (E111) and the second region (E112). Heat generated in the heat generating block (B) may spread to the second electronic component (E2) through the first region (E111). Heat generated in the heat generating block (B) may spread to the second portion (432) of the heat transfer member (430) through the second region (E112).
[0212] According to one embodiment of the present disclosure, the heat generating block (B) may include a first heat generating block (B1) and a second heat generating block (B2). The first heat generating block (B1) and the second heat generating block (B2) may be positioned below the first surface (E11) and overlap with the second area (E112). As an example, the first heat generating block (B1) may be a CPU of a processor (e.g., a processor (120) of FIG. 1), and the second heat generating block (B2) may be a GPU of the processor (e.g., a processor (120) of FIG. 1).
[0213] According to one embodiment of the present disclosure, the first electronic component (E1) may include a heat generating block (B). The heat generating block (B) may be a portion of the first electronic component (E1) having a relatively large amount of heat generation. As an example, the first electronic component (E1) may include a processor (e.g., the processor (120) of FIG. 1), and the heat generating block (B) may be a CPU / GPU portion and include at least one processing core. As another example, the heat generating block (B) may include any one of a plurality of processing cores, or a plurality of cores adjacent to each other.
[0214] According to one embodiment of the present disclosure, a heating block (B) may be positioned at an edge of a first electronic component (E1) to be connected to a power source (e.g., a battery (350) of FIG. 2). The heating block (B) may at least partially overlap a second area (E112) of a surface (E11, E12) of the first electronic component (E1). As an example, as illustrated in FIG. 3, the heating block (B) may overlap an edge of the second electronic component (E2) in a direction in which the first electronic component (E1) and the second electronic component (E2) are stacked. As another example, unlike as illustrated in FIG. 3, the heating block (B) may be positioned outside the edge of the second electronic component (E2) so as not to overlap an edge of the second electronic component (E2) in a direction in which the first electronic component (E1) and the second electronic component (E2) are stacked.
[0215] As electronic components (e.g., processors, memory, etc.) become more integrated and their performance becomes more advanced, the amount of heat generated by these components is increasing. Failure to reduce the temperature of these components due to heat generation can impact the operation of electronic devices (e.g., performance degradation due to throttling). Consequently, extensive research is being conducted on the heat dissipation structures of electronic components.
[0216] A problem to be solved in the present disclosure may be to minimize the flow of a gel-like heat dissipating material inside an electronic device.
[0217] A problem to be solved in the present disclosure may be to reduce the amount of heat dissipation material while ensuring the heat dissipation performance of an electronic component (e.g., an application processor).
[0218] A problem to be solved in the present disclosure may be to prevent the surface of an electronic device from being locally overheated due to the operation of electronic components.
[0219] The problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.
[0220] An electronic device according to various embodiments of the present disclosure can minimize the flow of a heat-dissipating material in an internal space of the electronic device by arranging a configuration (e.g., a shield can) in an internal space of the electronic device into which a heat-dissipating material in a gel form is injected.

[0222] An electronic device according to various embodiments of the present disclosure can reduce a user's perceived temperature by preventing local overheating on the surface of the electronic device by arranging a heat dissipating member (e.g., a vapor chamber) and an insulating layer on one side and the other side of an electronic component, respectively.
