[0085] According to an exemplary embodiment, the window (201b) may be coupled with the edge part (218). For example, the window (201b) may include an outer portion extending outside the display (201) when viewed in the z-axis direction, and may be adhered to the edge part (218) through an adhesive member (e.g., waterproof tape) disposed between the outer portion of the window (201b) and the edge part (218). However, the present invention is not limited to the above-described example.

According to an exemplary embodiment, the first printed circuit board (251) and the second printed circuit board (252) may be operatively or electrically connected to each other via a connecting member (e.g., a flexible printed circuit board).
[0087] According to an exemplary embodiment, a battery (270) (e.g., battery (189) of FIG. 1 ) may power at least one component of the electronic device (101). For example, the battery (270) may include a rechargeable secondary battery or a fuel cell. At least a portion of the battery (270) may be disposed substantially coplanar with the first printed circuit board (251) and / or the second printed circuit board (252).

[0089] According to an exemplary embodiment, a first camera module (205) (e.g., a front camera) may be positioned on at least a portion of the bracket (243) such that the lens can receive external light through a portion (e.g., the camera area (237)) of the window (201b) (e.g., the front (200A) of FIG. 2).
[0090] According to an exemplary embodiment, a second camera module (212) (e.g., a rear camera) may be disposed between the bracket (243) and the rear cover (211). According to an exemplary embodiment, the second camera module (212) may be electrically connected to the first printed circuit board (251) via a connecting member (e.g., a connector). According to an exemplary embodiment, the second camera module (212) may be disposed such that a lens can receive external light through the camera area (284) of the rear cover (211) of the electronic device (101).
[0091] According to an exemplary embodiment, the camera area (284) may be formed on a surface of the rear cover (211) (e.g., the rear surface (200B) of FIG. 2). According to an exemplary embodiment, the camera area (284) may be formed to be at least partially transparent so that external light may be incident on the lens of the second camera module (212). According to an exemplary embodiment, at least a portion of the camera area (284) may protrude from the surface of the rear cover (211) by a predetermined height. However, the present invention is not limited thereto, and according to an exemplary embodiment, the camera area (284) may form a substantially same plane as the surface of the rear cover (211).
[0092] According to an exemplary embodiment, the housing assembly (210) of the electronic device (101) may refer to a configuration or structure that forms at least a portion of the exterior of the electronic device (101). In this respect, at least a portion of the window (201b), the edge part (218), the bracket (243), and / or the rear cover (211) that form the exterior of the electronic device (101) may be referred to as the housing assembly (210) of the electronic device (101).
[0093] The electronic device (101) described below may include a housing assembly (210) comprising dissimilar metals. According to an exemplary embodiment, the edge part (218) may include a first metal material, and the bracket (243) may include a second metal material. In the examples described below, the first metal is described as titanium or zinc, and the second metal is described as aluminum, but is not limited thereto.
[0094] Fig. 4a illustrates an electronic device according to an exemplary embodiment. Fig. 4b illustrates an edge part of a frame according to an exemplary embodiment. Fig. 4c illustrates a bracket of a frame according to an exemplary embodiment.
[0095] An electronic device (101) according to an exemplary embodiment may include a display (201) and a frame (300).
[0096] According to an exemplary embodiment, the display (201) may be configured to display visual information. The display (201) may include a display panel (e.g., the display panel (201a) of FIG. 3) and a window (e.g., the window (201b) of FIG. 3). For example, the electronic device (101) may include a display driver integrated circuit (DDI) configured to control the display (201). The display driver circuit may be configured to control a plurality of pixels included in the display panel (201a) to display visual information through the display (201). The window (201b) may be disposed at the outermost portion of the display (201) to protect the display (201). The window (201b) may include a substantially transparent material so that the visual information displayed through the display (201) may be viewed from the outside. The window (201b) may be attached to the display panel (201a).
[0097] According to an exemplary embodiment, the frame (300) may support the display (201). For example, the edge of the window (201b) may be attached to the edge of the frame (300). The frame (300) may be positioned below (e.g., in the -z direction) the display (201). According to an exemplary embodiment, the frame (300) may include an edge part (218) and a bracket (243). A rear cover (e.g., the rear cover (211) of FIG. 3) may be coupled below (e.g., in the -z direction) the frame (300). The rear cover (211) may define the back of the electronic device (101). The rear cover (211) may be opposite to the display (201).
[0098] According to an exemplary embodiment, the edge part (218) may at least partially define a side surface (200C) of the electronic device (101). The edge part (218) may be referred to as a side bezel, or a side structure, in terms of defining the side surface (200C) of the electronic device (101).
[0099] According to an exemplary embodiment, the bracket (243) may be surrounded by the edge part (218). For example, the bracket (243) may be coupled to the inner surface of the frame (300). The bracket (243) may be configured to support components of the electronic device (101). For example, electronic components such as a printed circuit board (e.g., printed circuit board (250) of FIG. 3) and a battery (e.g., battery (270) of FIG. 3) may be supported by the bracket (243) by being placed on the bracket (243). The bracket (243) may be referred to as a support member, a support part, or a support plate from the perspective of supporting the components of the electronic device (101). The gap between the edge part (218) and the bracket (243) may be filled with an injection part (310).
[0100] Referring to FIG. 4B, the edge part (218) may have a shape including a hollow space therein. At least a portion of the edge part (218) may include one or more conductive portions (410) to function as an antenna radiator used for communication with an external electronic device.
[0101] When one or more conductive portions (410) operate as antenna radiators, the resonant frequency of a signal transmitted and / or received through one or more conductive portions (410) can be determined based on the electrical length of one or more conductive portions (410). For example, when the wavelength corresponding to the resonant frequency of the signal is w, the electrical length of one or more conductive portions (410) for transmitting and / or receiving a signal having the resonant frequency can be 1 / 4w to 1 / 2w.
[0102] To adjust the electrical length of one or more conductive portions (410), the edge part (218) may include a slot (or slit) (415). The slot (or slit) (415) may be filled with a non-conductive material to determine the electrical length of one or more conductive portions (410) that act as antenna radiators and to electrically isolate one or more conductive portions (410) from other conductive portions. When the slot (or slit) (415) is filled with a non-conductive material, one or more non-conductive portions (e.g., one or more non-conductive portions (420) of FIG. 7h) that contact one or more conductive portions (410) may be formed.
[0103] According to an exemplary embodiment, the edge part (218) may be exposed to the outside of the electronic device (101) because it at least partially defines the side surface (200C) of the electronic device (101). The edge part (218) may be required to have relatively high strength, hardness, and excellent surface properties in order to protect components disposed inside the electronic device (101) from external impact. If the strength of the edge part (218) is low, the electronic device (101) may be easily damaged by external impact, thereby causing damage to the electronic components inside. If the surface properties of the edge part (218) are poor, the edge part (218) may be easily corroded, thereby deteriorating the surface quality of the electronic device (101). For high strength and excellent surface properties, the edge part (218) may include a first metal material having high strength and excellent surface properties. For example, the first metal material may include, but is not limited to, titanium, zinc, and / or stainless steel, which have high strength and excellent corrosion resistance.
[0104] Referring to FIG. 4c, the bracket (243) may be coupled to the inside of an edge part (e.g., an edge part (218) of FIG. 4b) by die casting. The bracket (243) may not be exposed to the outside of the electronic device (101) by being wrapped by the edge part (218). The bracket (243) may be formed of a second metal material having a lower specific gravity than the edge part (218). Since the bracket (243) is disposed inside the electronic device (101) and is not visible from the outside of the electronic device (101), it may be formed of a second metal material having a relatively lower specific gravity, and thus, the overall weight of the electronic device (101) may be reduced.
[0105] For example, if the bracket (243) is formed of titanium, identical to the edge part (218), the overall weight of the electronic device (101) may increase. The specific gravity of titanium (e.g., about 4.5 g / cm 3 ) and the specific gravity of zinc (e.g., about 7.14 g / cm 3 ) is lower than that of metal materials such as iron and stainless steel, but the specific gravity of aluminum (e.g. about 2.7 g / cm 3 ), the relatively high specific gravity of titanium or zinc may cause an increase in the weight of the electronic device (101). If the weight of the electronic device (101) is too heavy, a problem of reduced portability of the electronic device (101) may occur.
[0106] According to an exemplary embodiment, the bracket (243) may include a different metal material from the edge part (218). For example, the bracket (243) may include a second metal material that is relatively lighter than the first metal material included in the edge part (218). The specific gravity of the second metal material may be lower than the specific gravity of the first metal material. Unlike the edge part (218), the bracket (243) wrapped by the edge part (218) is not exposed to the outside of the electronic device (101), but is at least partially wrapped by the edge part (218), thereby being disposed inside the electronic device (101). Since the bracket (243) is disposed inside the electronic device (101), even if the bracket (243) has a lower strength than the edge part (218), the bracket (243) may have a small effect on the rigidity of the electronic device (101).
[0107] According to an exemplary embodiment, the second metal material may include aluminum and / or magnesium, which are relatively lighter than the first metal material (e.g., titanium). However, the present invention is not limited thereto. Since the specific gravity of aluminum is lower than the specific gravity of titanium and the specific gravity of zinc, an electronic device (101) including a bracket (243) including aluminum may be lighter than an electronic device according to a comparative example including a bracket (243) including titanium.
[0108] According to an exemplary embodiment, the edge part (218) and the bracket (243) may be manufactured in separate processes. The bonding strength between the edge part (218) and the bracket (243) may require a bonding strength that is not easily separated by external impact. For example, the bonding strength between the edge part (218) and the bracket (243) may be required to be about 10 MPa or more.
[0109] The edge part (218) and the bracket (243) may be manufactured through separate processes. A separate process may be performed to join the edge part (218) and the bracket (243) manufactured through separate processes. The joining process of the edge part (218) and the bracket (243) may vary. For example, a process may be performed in which the edge part (218) and the bracket (243) are manufactured separately, and then the bracket (243) is welded to the edge part (218). The process for welding dissimilar metals may include laser welding, electron-beam welding, and / or friction stir welding.
[0110] In the process of joining the edge part (218) and the bracket (243) by welding, bubbles may be generated inside the edge part (218) and / or the bracket (243) during the welding process. For example, if the difference in melting points between the first metal material included in the edge part (218) and the second metal material included in the bracket (243) is large, the welding process may be performed at a temperature higher than the higher melting point. In this case, the temperature at which the welding process is performed may cause vaporization of the metal material having the lower melting point. As the metal material having the relatively low melting point vaporizes, gas may be generated. The gas may cause the formation of bubbles inside during the welding process.
[0111] For example, when the first metal material is titanium and the second metal material is aluminum, the melting point of titanium is approximately 2,850°C, and the melting point of aluminum is approximately 659°C. Since the welding process may be performed at a temperature higher than the melting point of titanium (e.g., approximately 2,850°C), the temperature at which the welding process is performed may be too high compared to the melting point of aluminum. Due to the high temperature, the aluminum may vaporize and generate gas, and the gas may create bubbles.
[0112] For example, when the first metal material is zinc and the second metal material is aluminum, the melting point of zinc is about 419°C and the melting point of aluminum is about 659°C. Since the welding process can be performed at a temperature higher than the melting point of aluminum (e.g., about 659°C), the temperature at which the welding process is performed may be too high compared to the melting point of zinc. Due to the high temperature, the zinc may vaporize and generate gas, and the gas may generate bubbles. The generation of bubbles may form an irregular bonding surface. If the bonding surface is irregular, a weakening of the bonding strength may occur. In addition, in the case of the welding process, since an additional welding process is required after each of the edge part (218) and the bracket (243) is manufactured, the manufacturing time and manufacturing cost may increase.
[0113] The process of joining the edge part (218) and the bracket (243) may include a method of die casting a second metal material on the inside of the edge part (218). In the case of the die casting process, the bracket (243) joined to the edge part (218) may be formed by seating the edge part (218) in a die and casting the second metal material forming the bracket (243) on the inside of the edge part (218). When the edge part (218) and the bracket (243) include different metal materials, the bonding force between the edge part (218) and the bracket (243) may be weak due to differences in physical properties and chemical properties between the dissimilar metals. In order to improve the bonding force between dissimilar metals (e.g., titanium and aluminum), a special treatment may be required for the bonding surface. For example, by adjusting the inner roughness of the edge part (218) using a method such as Laser Hatching or Blasting, a concavo-convex portion is formed, and by infiltrating aluminum into the concavo-convex portion, the bracket (243) can be joined to the edge part (218). In the case of the above process, a separate process for forming the concavo-convex portion may be required for roughness.
[0114] According to an exemplary embodiment, a frame (300) of an electronic device (101) may include a porous part (e.g., a porous part (500) of FIG. 5A) for bonding between an edge part (218) and a bracket (243). A plurality of pores may be formed inside the porous part (500). The porous part (500) may be disposed between the edge part (218) and the bracket (243) and bonded to each of the edge part (218) and the bracket (243). The porous part (500) may be bonded to the edge part (218) by solidifying after a first metal material forming the edge part (218) permeates into some of the plurality of pores of the porous part (500). Within the present disclosure, a portion of the porous part (500) that is joined to the edge part (218) by the first metal material penetrating into some of the pores of the porous part (500) and then solidifying is defined as a first portion (e.g., the first portion (510) of FIG. 5A). Within the present disclosure, a portion of the pores of the porous part (500) into which the first metal material penetrating and then solidifying is defined as a third portion.
[0115] In one embodiment, the porous part (500) may be joined to the bracket (243) by the second metal material forming the bracket (243) penetrating into another portion of the plurality of pores of the porous part (500) and then solidifying. Within the present disclosure, the portion of the porous part (500) that is joined to the bracket (243) by the second metal material penetrating into another portion of the plurality of pores of the porous part (500) and then solidifying is defined as the second portion (e.g., the second portion (520) of FIG. 5A). The first metal material and the second metal material may penetrate the porous part (500) in opposite directions. For example, the first metal material may penetrate into one side of the porous part, and the second metal material may penetrate into the other side of the porous part. Within the present disclosure, the other portions of the plurality of pores of the porous part (500) that are solidified after the second metal material has penetrated are defined as fourth portions. The third portions and the fourth portions may be pores before the first metal material or the second metal material has penetrated, and may be portions filled with the first metal material or the second metal material after the first metal material or the second metal material has penetrated and solidified.
[0116] According to an exemplary embodiment, an edge part (218) to be joined with the porous part (500) can be manufactured by die casting a first metal material in a liquid state forming the edge part (218) onto one side of the porous part (500). Thereafter, a bracket (243) to be joined with the porous part (500) can be manufactured by die casting a second metal material in a liquid state forming the bracket (243) onto the other side of the porous part (500). By die casting the first metal material and the second metal material, the first metal material or the second metal material naturally penetrates into the plurality of pores of the porous part (500), thereby forming the edge part (218) and the bracket (243) to be joined with the porous part (500). The edge part (218) and the bracket (243) can be joined firmly and stably by being joined through the porous part (500).
[0117] Fig. 5a is a cross-sectional view of a frame according to an exemplary embodiment taken along line A-A' of Fig. 4a. Figs. 5b and 5c illustrate portions of a frame according to an exemplary embodiment.
[0118] Referring to FIG. 5A, the frame (300) may include an edge part (218), a bracket (243), and a porous part (500). The porous part (500) may be positioned between the edge part (218) and the bracket (243). The porous part (500) may be coupled to each of the edge part (218) and the bracket (243), thereby coupling the edge part (218) and the bracket (243).
[0119] According to an exemplary embodiment, the porous part (500) may include a first portion (510) and a second portion (520). Referring to FIG. 5B, the first portion (510) may be a portion of the porous part (500) that is coupled with the edge portion (218), and may be a portion into which a first metal material forming the edge portion (218) has penetrated. For example, at least some of the pores included in the first portion (510) may be filled with the first metal material, and the pores filled with the first metal material may be referred to as third portions (511). When the first metal material is zinc, the first portion (510) may include third portions (511) filled with zinc. The first metal material may be present across the edge part (218) and the first portion (510) by penetrating into the pores from the edge part (218) and then solidifying. The porous portion (500) may be joined to the edge part (218) via the first portion (510) including the third portions (511).
[0120] According to an exemplary embodiment, the edge part (218) can be formed by die casting a first metal material in a liquid state. A first die (e.g., the first die (720) of FIG. 7B) for forming the edge part (218) can be used. The edge part (218) can be formed by casting a first metal material in a liquid state (e.g., molten metal) into a first cavity (e.g., the first cavity (721) of FIG. 7B) of the first die (720). When manufacturing the edge part (218), when the porous part (500) is placed in the first cavity (721) and the first metal material in a liquid state is cast onto one side of the porous part (500), the first metal material can penetrate into the pores of the porous part (500) while forming the edge part (218). By the above process, a porous part (500) and an edge part (218) that are joined to each other can be manufactured. The above process will be described later.
[0121] Referring to FIG. 5C, the second portion (520) may be another portion of the porous part (500) that is coupled with the bracket (243), and may be a portion into which the second metal material forming the bracket (243) has penetrated. For example, at least some of the pores included in the second portion (520) may be filled with the second metal material, and the pores filled with the second metal material may be referred to as fourth portions (521). When the second metal material is aluminum, the second portion (520) may include fourth portions (521) filled with aluminum. The second metal material may penetrate into the pores from the bracket (243) and then solidify, thereby existing across the bracket (243) and the second portion (520). The porous part (500) can be coupled to the bracket (243) through the second part (520) including the fourth parts (521).
[0122] According to an exemplary embodiment, the bracket (243) may be formed by die casting a second metal material in a liquid state. A second die (e.g., the second die (730) of FIG. 7D) may be used to form the bracket (243). The bracket (243) may be formed by casting the second metal material in a liquid state (e.g., molten metal) into a second cavity (e.g., the second cavity (731) of FIG. 7D) of the second die (730). When manufacturing the bracket (243), the porous part (500) and the edge part (218) that are joined to each other are placed in the second cavity (731), and a second metal material in a liquid state is cast on the other side of the porous part (500) opposite to one side of the porous part (500), so that the second metal material can penetrate into the pores of the porous part (500) while forming the bracket (243). By the above process, the edge part (218) and the bracket (243) that are joined through the porous part (500) can be manufactured. The above process will be described later.
[0123] According to an exemplary embodiment, the edge part (218) and the bracket (243) can be coupled through the porous part (500). Third portions (e.g., third portions (511) in FIG. 5B) filled with the first metal material in the first portion (510) can couple the first portion (510) of the porous part (500) to the edge part (218). Fourth portions (e.g., fourth portions (521) in FIG. 5C) filled with the second metal material in the second portion (520) can couple the second portion (520) of the porous part (500) to the bracket (243). At least some of the plurality of pores of the porous part (500) are filled with the first metal material and the second metal material, thereby stably coupling the edge part (218) and the bracket (243). When the edge part (218) and the bracket (243) including different metal materials are directly bonded, electrochemical corrosion may occur due to contact between the different metal materials, which may weaken the bonding strength or cause uneven bonding strength. According to an exemplary embodiment, the above problems can be solved by indirectly bonding the edge part (218) and the bracket (243) through the porous part (500). The edge part (218) can be bonded to the porous part (500) through the third portions of the porous part (500), and the bracket (243) can be bonded to the porous part (500) through the fourth portions of the porous part (500), so that a stable and firm bonding can be achieved.
[0124] Hereinafter, a method for manufacturing a frame (300) according to an exemplary embodiment is described.
[0125] Figure 6 is a flowchart showing a method for manufacturing a frame according to an exemplary embodiment.
[0126] Referring to FIG. 6, in operation 601, a porous part (e.g., porous part (500) of FIG. 7a) may be provided (prepared).
[0127] According to an exemplary embodiment, the porous part (500) may include a plurality of pores. FIG. 7A illustrates a porous part (500) according to an exemplary embodiment. The porous part (500) may include a plurality of pores (710) having a diameter ranging from about 10 μm to about 1,000 μm. As described below, by performing die casting, at least some of the plurality of pores (710) may be filled with a first metal material forming an edge part (e.g., edge part (218) of FIG. 4A), and other some of the plurality of pores (710) may be filled with a second metal material forming a bracket (e.g., bracket (243) of FIG. 4A).
[0128] The porous part (500) can be manufactured by three-dimensional printing (additive manufacturing) or metal injection molding (MIM). For example, when manufacturing the porous part (500) using metal injection molding, the binder content can be adjusted so that a plurality of pores can be formed after the powders are crystallized through a debinding process and a sintering process. The porous part (500) can be manufactured by a closed-cell casting method or a continuous-cell casting method. The continuous-cell casting method can include various methods such as sintered metal powder, a space holder method, a combustion synthesis method, and CVD (chemical vapor deposition). The method for manufacturing the porous part (500) is not limited to the above-described method, and various methods can be used.
[0129] Referring again to FIG. 6, at operation 603, a porous part (500) may be seated within a first cavity (e.g., the first cavity (721) of FIG. 7b) of a first die (e.g., the first die (720) of FIG. 7b). The first die (720) may be used for die casting to manufacture an edge part (218).
[0130] In operation 605, a first metal material in a liquid state can be cast into the first cavity (721).
[0131] Figure 7b illustrates a process for manufacturing an edge part (218) according to an exemplary embodiment. Die casting is a process of forming a metal material (molten metal) in a liquid state by injecting it into a cavity of a die. Die casting can provide excellent productivity, high dimensional accuracy, and a simple post-processing process. The first cavity (721) of the first die (720) can have a shape for forming the edge part (218). A first metal material in a liquid state can be cast into the first cavity (721). When the first metal material is cast into the first cavity (721), the first metal material can flow along the first cavity (721) for forming the edge part (218). The first metal material in a liquid state can penetrate into the first pores among the plurality of pores of the porous part (500) within the first cavity (721).
[0132] Referring again to FIG. 6, in operation 607, after casting the first metal material in a liquid state, the first intermediate structure (701) can be formed by solidifying the first metal material in a liquid state.
[0133] Fig. 7c illustrates a first intermediate structure (701). Referring to Fig. 7c, the first intermediate structure (701) may be referred to as an intermediate structure in which the edge part (218) is coupled to the first portion (510) of the porous portion (500). The first pores included in the first portion (510) may be filled with the first metal materials by solidifying after the first metal materials forming the edge part (218) have penetrated therein. As described above, the first pores filled with the first metal materials may be referred to as third portions (e.g., the third portions (511) of Fig. 5b). Since the first intermediate structure (701) is in a state before the bracket (243) is formed, the interior of the edge part (218) may be empty. Referring to FIG. 7C, the first metal material forming the edge part (218) can penetrate into the first part (510), thereby firmly bonding the edge part (218) and the porous part (500). In FIG. 7C, the edge part (218) of the first intermediate structure (701) is illustrated as an integrally formed structure, but the embodiment is not limited thereto. For example, the edge part (218) can have a segmented structure including a slot (e.g., a slot or slit (415) of FIG. 4B). The first part (510) of the porous part (500) can be bonded to the inner surface of the edge part (218) having the segmented structure.
[0134] Referring again to FIG. 6, at operation 609, the first intermediate structure (701) may be separated from the first die (720) and placed within the second cavity (731) of the second die (730). The second die (730) may be used for die casting to manufacture the bracket (243).
[0135] In operation 611, a second metal material in a liquid state can be cast into the second cavity (731).
[0136] FIG. 7D illustrates a process for manufacturing a bracket (243) according to an exemplary embodiment. The second cavity (731) of the second die (730) may have a shape for forming the bracket (243). A second metal material in a liquid state may be cast into the second cavity (731). When the second metal material is cast into the second cavity (731), the second metal material may flow along the second cavity (731) for forming the bracket (243). The second metal material in a liquid state may penetrate into the second pores among the plurality of pores of the porous part (500) within the second cavity (731).
[0137] Referring again to FIG. 6, in operation 613, after casting the second metal material in a liquid state, a second intermediate structure (702) can be formed by solidifying the second metal material in a liquid state.
[0138] Fig. 7e illustrates a second intermediate structure (702). Referring to Fig. 7e, the second intermediate structure (702) may be referred to as an intermediate structure in which a bracket (243) is formed inside the first intermediate structure (701). In the second intermediate structure (702), the edge part (218) may be coupled to the first part (510) of the porous part (500), and the bracket (243) may be coupled to the second part (520) of the porous part (500). The second pores included in the second part (520) may be filled with second metal materials by solidifying after the second metal materials forming the bracket (243) have penetrated therein. As described above, the second pores filled with the second metal materials may be referred to as fourth parts (e.g., the fourth parts (521) of Fig. 5c). Since the second intermediate structure (702) is in a state after the bracket (243) is formed, a portion of the interior of the edge part (218) may be filled with the bracket (243). Referring to FIG. 7e, the second metal material forming the bracket (243) extends into the second portion (520), so that the bracket (243) and the porous part (500) may be firmly coupled. According to an exemplary embodiment, the edge part (218) and the bracket (243) may be stably coupled by the porous part (500).
[0139] According to one embodiment, the porous part (500) may be formed of a third metal material. In one embodiment, the melting point of the third metal material may be higher than the melting point of the first metal material and the melting point of the second metal material. If the melting point of the third metal material is lower than the melting point of the first metal material and the melting point of the second metal material, when the first metal material in a liquid state or the second metal material in a liquid state penetrates into the porous part (500), the porous part (500) may be damaged by the first metal material or the second metal material. When die casting the first metal material in a liquid state or the second metal material in a liquid state, in order to prevent deformation or deterioration of the properties of the porous part (500) due to high temperature, the melting point of the third metal material forming the porous part (500) should be higher than the melting point of the first metal material and the melting point of the second metal material. For example, when the second metal material is aluminum, in order to prevent the porous part (500) from being damaged when casting aluminum, the porous part (500) may be formed of a material (e.g., titanium, iron, copper, etc.) having a melting point higher than the melting point of aluminum (e.g., about 659°C).
[0140] Referring again to FIG. 6, at operation 615, the second intermediate structure (702) is separated from the second die (730), and the gap between the edge part (218) and the bracket (243) can be filled with the injection portion (310).
[0141] Figures 7f, 7g, and 7h illustrate the process of injecting resin into the gap between the edge part (218) and the bracket (243).
[0142] Referring to FIG. 7F, a gap may exist between the edge part (218) and the bracket (243). If the edge part (218) is entirely composed of a first metal material that is a conductive material, it may be difficult to use the edge part (218) as an antenna radiator because the resonant frequency of a signal radiated or received through the edge part (218) cannot be controlled. In order to use one or more conductive portions (410) of the edge part (218) as an antenna radiator, the edge part (218) may have a segmented structure. The segmented structure may be referred to as a structure of the edge part (218) that includes a plurality of segments that are separated from each other in order to determine the electrical length of one or more conductive portions (410). The electrical length of one or more conductive portions (410) can determine the frequency characteristics of a signal transmitted and / or received through the antenna radiator, so that one or more conductive portions (410) can be used as an antenna radiator for transmitting and / or receiving a signal on a specified frequency band.
[0143] FIG. 7g illustrates a process in which a resin (740) is injected between an edge part (218) and a bracket (243). Referring to FIG. 7g, the resin (740) may be injected to fill a gap between the edge part (218) and the bracket (243). The resin (740), which is a non-conductive material, fills at least a portion of the gap between the edge part (218) and the bracket (243), thereby allowing the edge part (218) and the bracket (243) to be firmly bonded together. The resin (740) may form one or more non-conductive portions (e.g., one or more non-conductive portions (420) of FIG. 7h) that come into contact with one or more conductive portions (410). By filling the empty portion of the edge part (218) with the resin (470), a segmented structure including one or more conductive portions (410) and one or more non-conductive portions (e.g., one or more non-conductive portions (420) of FIG. 7h) can be formed. For example, a wireless communication module (e.g., the wireless communication module (192) of FIG. 1) can be configured to transmit or receive a signal on a designated band using the one or more conductive portions (410). For example, the resin (740) may include, but is not limited to, polybutyleneterephthalate (PBT), which has excellent electrical properties and flame retardancy. For example, the resin (740) may also include polycarbonate (PC) and / or polyphthalamide (PPA).
[0144] Fig. 7h illustrates the final state of the frame (300) after processing. Referring to Fig. 7h, the resin (740) can form the injection-molded portion (310) of the bracket (243) by filling at least a portion of the gap between the edge part (218) and the bracket (243). After the injection-molded portion (310) is formed, a processing process for improving dimensional accuracy, a polishing process for improving the quality of the outer surface, and / or a coating process (e.g., PVD (physical vapor deposition) coating) for implementing color can be performed. For example, a cutting processing process for rounding the outer surface of the edge part (218) can be performed.
[0145] According to an exemplary embodiment, the porous part (500) and the edge part (218) may be joined by a first metal material that has penetrated into some of the plurality of pores within the porous part (e.g., the porous part (500) of FIG. 7A) and then solidified. The porous part (500) and the bracket (243) may be joined by a second metal material that has penetrated into other of the plurality of pores within the porous part (500) and then solidified. The edge part (218) and the bracket (243) may be indirectly and firmly joined to each other via the porous part (500). An electronic device (101) according to an exemplary embodiment may have a joint structure of an edge part (218) and a bracket (243) using a porous part (500) without having to form a separate uneven portion on the inner side of the edge part (218) or adjust the roughness for jointing between the edge part (218) and the bracket (243). The above-described manufacturing method can improve the joint strength between the edge part (218) and the bracket (243) and reduce unnecessary processes, thereby reducing manufacturing costs.
[0146] According to an exemplary embodiment, the edge part (218) and the bracket (243) may include different metals. The edge part (218) exposed to the outside of the electronic device (101) may include a first metal material (e.g., titanium and / or zinc) having a relatively high strength for the rigidity of the electronic device (101). The bracket (243), which is disposed inside the electronic device (101) and not exposed to the outside, may include a second metal material (e.g., aluminum) having a relatively low specific gravity for the weight lightening of the electronic device (101). The exemplary electronic device (101) may provide a light weight while having a high rigidity.
[0147] Figure 8 illustrates a frame of an electronic device according to an exemplary embodiment.
[0148] Referring to FIG. 8, the frame (300) according to the exemplary embodiment may further include a fifth portion (530) disposed between the first portion (510) and the second portion (520). The fifth portion (530) may be surrounded by the first portion (510) and the second portion (520). The fifth portion (530) may include a plurality of empty pores (531) as a portion of the porous part (500) into which the first metal material and the second metal material do not penetrate.
[0149] According to an exemplary embodiment, the first metal material may penetrate into the third portions of the first portion (510) and then solidify, thereby joining the first portion (510) and the edge portion (218). The second metal material may penetrate into the fourth portions of the second portion (520) and then solidify, thereby joining the second portion (520) and the bracket (243). The fifth portion (530) may include a plurality of empty pores (531) formed so as to prevent the first metal material and the second metal material from penetrating.
[0150] In order to infiltrate the first metal material into the first portion (510) or the second metal material into the second portion (520), the third portions (511) within the first portion (510) and the fourth portions (521) within the second portion (520) may have relatively large sizes. The pores within the first portion (510) before the first metal material infiltrates and the pores within the second portion (520) before the second metal material infiltrates may have relatively large sizes. In the case of the plurality of pores (531) within the fifth portion (530), they may have relatively small sizes to prevent the first metal material and the second metal material from infiltrating.
[0151] According to an exemplary embodiment, within the first portion (510), the first size of the third portions (511) into which the first metal material has penetrated and / or within the second portion (520), the second size of the fourth portions (521) into which the second metal material has penetrated may be larger than the third size of the plurality of pores (531) within the fifth portion (530). Because the third size is smaller than the first size and the second size, the first metal material and the second metal material may not penetrate into the plurality of pores (531) within the fifth portion (530).
[0152] According to an exemplary embodiment, the density of the third portions (511) within the first portion (510), the density of the fourth portions (521) within the second portion (520), and the density of the plurality of voids (531) within the fifth portion (530) may be different due to the differences in the first size, the second size, and the third size. The density may indicate how many voids are present.
[0153] For example, the density of pores in the first portion (510) before the first metal material penetrates and the density of pores in the second portion (520) before the second metal material penetrates may be relatively low because they are not dense due to pores having relatively large sizes. The density of pores in the fifth portion (530) may be relatively high because they are dense due to pores having relatively small sizes. According to an exemplary embodiment, the first density of the third portions (511) in the first portion (510) and the second density of the fourth portions (521) in the second portion (520) may be lower than the third density of the plurality of pores in the fifth portion (530). The pore ratio of the fifth portion (530) may be higher than the pore ratio of the first portion (510) and the pore ratio of the second portion (520). The pore ratio may be higher as more pores are included in a certain volume.
[0154] According to an exemplary embodiment, even if the first metal material and the second metal material do not penetrate the entire porous part (500), the porous part (500) can be joined to the edge part (218) and the bracket (243). If the porous part (500) includes a plurality of pores that are not filled with the metal material, the weight of the frame (300) can be reduced. As illustrated in FIG. 8, if the porous part (500) includes a third portion including a plurality of pores, the weight of the frame (300) can be reduced, thereby enabling a weight reduction of the electronic device (101).
[0155] Figures 9a, 9b, 9c, and 9d illustrate various embodiments of porous parts.
[0156] Referring to FIGS. 9a, 9b, 9c, and 9d, the porous part (500) can have various shapes.
[0157] Referring to FIG. 9A, the porous part (500) may have a rectangular cross-section. The edge part (218) may be joined to the porous part (500) by a first metal material that has penetrated into a portion of the rectangular cross-section.
[0158] Referring to FIG. 9B, the first portion (510) of the porous part (500) may include a groove portion (910). The groove portion (910) may be formed by recessing from an outer surface of the first portion (510) into the interior of the first portion (510). When a first metal material for forming the edge portion (218) is cast, the first metal material may be filled in the groove portion (910) and then solidified. As the first metal material filled in the groove portion (910) solidifies, a contact area between the first portion (510) and the edge portion (218) may increase. An increase in the contact area may improve a bonding force between the porous part (500) and the edge portion (218), so that the edge portion (218) may be firmly and stably bonded to the porous part (500). In FIG. 9B, the groove portion (910) is illustrated as being formed on the side surface of the first portion (510), but the embodiment is not limited thereto. To enhance the bonding strength, the shape of the groove portion (910) may have a dovetail shape or an undercut shape. Since the edge portion (218) can be strongly bonded to the first portion (510) by the groove portion (910), the bonding strength between the edge portion (218) and the porous portion (500) can be enhanced.
[0159] Referring to FIG. 9c, at least a portion of the outer surface (510a) of the first portion (510) may have a shape corresponding to the shape of the outer surface (218a) of the edge part (218). According to an exemplary embodiment, at least a portion of the outer surface (218a) of the edge part (218) may be rounded. If the outer surface (218a) of the edge part (218) is angular, the grip of the electronic device (101) may be reduced, the device may be easily damaged by impact, thereby weakening its durability and deteriorating its design aesthetics. To solve the above problems, a cutting process may be performed so that the edge part (218) has a rounded outer surface (218a).
[0160] According to an exemplary embodiment, at least a portion of the outer surface (510a) of the first portion (510) may have a shape corresponding to the shape of the outer surface (218a) of the edge part (218). Since at least a portion of the outer surface (510a) of the first portion (510) has a shape corresponding to the shape of the outer surface (218a) of the edge part (218), penetration of the first metal material may be facilitated. By facilitating penetration of the first metal material, the bonding force between the edge part (218) and the porous part (500) may be increased. When the outer surface (218a) of the edge part (218) is rounded, the outer surface (510a) of the first portion (510) may also be rounded.
[0161] Referring to FIG. 9d, the first part (510) includes a groove part (910), and at least a portion of an outer surface (510a) of the first part (510) may have a shape corresponding to an outer surface of the edge part (218). According to an exemplary embodiment, the bonding force between the edge part (218) and the first part (510) may be increased through the groove part (910) and at least a portion of the outer surface (510a).
[0162] Figures 10a, 10b, 10c, 10d, and 10e illustrate various embodiments of porous parts.
[0163] Referring to FIGS. 10a, 10b, 10c, 10d, and 10e, the porous part (500) including the third portion may have various shapes.
[0164] Referring to FIG. 10A, the porous part (500) may have a rectangular cross-section. The edge part (218) may be joined to the porous part (500) by a first metal material that has penetrated into a portion of the rectangular cross-section (the first portion (510)). The bracket (243) may be joined to the bracket (243) by a second metal material that has penetrated into another portion of the rectangular cross-section (the second portion (520)). The plurality of pores within the fifth portion (530) may be empty and not filled with the first metal material or the second metal material.
[0165] Referring to FIG. 10B, the first portion (510) of the porous part (500) may include a groove portion (910). The groove portion (910) may be formed by recessing from an outer surface of the first portion (510) into the interior of the first portion (510). By the groove portion (910), the edge portion (218) may be brought into contact with the fifth portion. The plurality of pores within the fifth portion may have a relatively small size to prevent the first metal material or the second metal material from penetrating. When the first metal material for forming the edge portion (218) is cast, the first metal material may be filled in the groove portion (910) and then solidified. As the first metal material filled in the groove portion (910) solidifies, the contact area between the first portion (510) and the edge portion (218) may increase. An increase in the contact area can improve the bonding force between the porous part (500) and the edge part (218), so that the edge part (218) can be firmly and stably bonded to the porous part (500). In FIG. 10b, the groove part (910) is illustrated as being formed on the side surface of the first part (510), but the embodiment is not limited thereto. To improve the bonding force, the shape of the groove part (910) may have a dovetail shape or an undercut shape.
[0166] Referring to FIG. 10c, the first portion (510) and the second portion (520) may be spaced apart from each other. Comparing the example illustrated in FIG. 10a with the example illustrated in FIG. 10c, the weight reduction effect of the frame (300) can be improved by increasing the size of the fifth portion.
[0167] Referring to FIGS. 10d and 10e, at least a portion of the outer surface (510a) of the first portion (510) may have a shape corresponding to the shape of the outer surface (218a) of the edge part (218).

At least a portion of the outer surface (510a) of the first portion (510) may be rounded to correspond to the shape of the outer surface (218a) of the edge part (218). Since at least a portion of the outer surface (510a) of the first portion (510) has a shape corresponding to the shape of the outer surface (218a) of the edge part (218), the penetration of the first metal material may be facilitated. By facilitating the penetration of the first metal material, the bonding force between the edge part (218) and the porous part (500) may be increased.

A state (1102) of FIG. 11A illustrates the frame (300) after die casting the second metal material. Referring to the above state (1102), a bracket (243) can be formed by positioning a plurality of porous parts (500, 1100) at a plurality of points on the inner surface of an edge part (218) and then die casting a second metal material. The edge part (218) and the bracket (243) can be joined through the plurality of porous parts (500, 1100) that are spaced apart from each other. From the perspective that the edge part (218) and the bracket (243) are joined at each of the positions where the plurality of porous parts (500, 1100) are positioned, the structure illustrated in FIG. 11A can be referred to as a point joining structure.

In the state (1103), the porous part (500) can be positioned at one position on the inner surface of the edge part (218), and other porous parts (1100) can be positioned at other positions of the edge part (218). State (1104) of Fig. 11b shows the frame (300) after die casting the second metal material. Referring to the state (1104), a bracket (243) can be formed by die casting the second metal material after positioning a plurality of porous parts (500, 1100) at a plurality of points on the inner surface of the edge part (218).
[0173] According to an exemplary embodiment, the structure illustrated in FIG. 11B may be referred to as a surface bonding structure in that the edge part (218) and the bracket (243) are joined through the areas of the plurality of elongated porous parts (500, 1100). Since the frame (300) illustrated in FIG. 11B has a relatively large area in which the plurality of porous parts (500, 1100) come into contact with the edge part (218) and the bracket (243), the bracket (243) and the edge part (218) can be firmly joined through the plurality of porous parts (500, 1100).
