Abstract
Description
Shielding member and electronic device including same
[0001] Various embodiments of the present disclosure relate to electromagnetic shielding of electronic devices, and more particularly, to shielding members and electronic devices including the same.
[0002] Electronic devices include printed circuit boards (PCBs) on which various electrical components are arranged. For example, the PCB may include a card slot that accepts an integrated circuit (IC) card inserted into the electronic device. The IC card may include, for example, a subscriber identity module (SIM) card and / or a memory card.
[0003] A printed circuit board of an electronic device may include a shielding member (e.g., a shielding can) arranged to protect various electrical components arranged thereon from external electromagnetic interference (EMI) or to protect other electrical components from electromagnetic interference (EMI) generated by the electrical components. The shielding member may be arranged on the printed circuit board and grounded.
[0004] When reducing the size of a printed circuit board to reduce the size of an electronic device, the distance between components on the printed circuit board may become shorter. For example, the distance between a card socket and a shielding member may decrease. Accordingly, due to positional errors that occur when placing the card socket on the printed circuit board, the terminals (pins) of the card socket may come into electrical contact with the shielding member, which may cause defects and failures, such as short circuits and / or signal distortion, in the electronic device.
[0005] According to various embodiments of the present disclosure, an electronic device with reduced risk of short circuit in a card socket can be provided.
[0006] An electronic device according to various embodiments of the present disclosure may be an electronic device including a card socket into which a card is inserted. The electronic device may include a printed circuit board configured to have the card socket and at least one electrical component disposed thereon. The electronic device may include at least one signal terminal formed in the card socket and configured to be electrically connectable with the card inserted into the card socket. The electronic device may include a shielding member disposed at a position adjacent to the card socket on one surface of the printed circuit board. The shielding member may include an upper surface formed to cover the at least one electrical component. The shielding member may include a shielding member having a first side surface extending from the upper surface toward the one surface of the printed circuit board and adjacent to the card socket. The shielding member may have at least one opening formed in a region adjacent to the signal terminal on the first side surface.
[0007] A printed circuit board according to various embodiments of the present disclosure may include a card socket disposed on a surface of the printed circuit board and configured to receive a card. The printed circuit board may include at least one signal terminal formed in the card socket and configured to be electrically connectable with the card inserted into the card socket. The printed circuit board may include a shielding member disposed at a position adjacent to the card socket on one surface of the printed circuit board. The shielding member may include an upper surface formed to cover the at least one electrical component. The shielding member may include a shielding member having a first side extending from the upper surface toward the one surface of the printed circuit board and adjacent to the card socket. The shielding member may have at least one opening formed in a region adjacent to the signal terminal on the first side.
[0008] According to various embodiments of the present disclosure, an electronic device can be provided in which a portion of a shielding member adjacent to a signal terminal of a card socket is cut out, thereby reducing the area of a printed circuit board by arranging the card socket and the shielding member adjacent to each other, and reducing the risk of a short circuit occurring with the signal terminal.

In connection with the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include one or more of the items, unless the context clearly indicates otherwise. In this document, each of the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can include any one of the items listed together in the corresponding phrase among those phrases, or all possible combinations thereof. Terms such as "first," "second," or "first" or "second" may be used merely to distinguish one component from another, and do not limit the components in any other respect (e.g., importance or order). When a component (e.g., a first component) is referred to as "coupled" or "connected" to another (e.g., a second component), with or without the terms "functionally" or "communicatively," it means that the component can be connected to the other component directly (e.g., wired), wirelessly, or through a third component.
[0031] The term "module" used in various embodiments of this document may include a unit implemented in hardware, software, or firmware, and may be used interchangeably with terms such as logic, logic block, component, or circuit. A module may be an integral component, or a minimum unit or part of such a component that performs one or more functions. For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).
[0032] Various embodiments of the present document may be implemented as software (e.g., a program (140)) including one or more instructions stored in a storage medium (e.g., an internal memory (136) or an external memory (138)) readable by a machine (e.g., an electronic device (100)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (100)) may call at least one instruction among the one or more instructions stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Here, 'non-transitory' simply means that the storage medium is a tangible device and does not contain signals (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently or temporarily on the storage medium.
[0033] According to one embodiment, the method according to various embodiments disclosed in the present document may be provided as included in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or may be distributed online (e.g., downloaded or uploaded) through an application store (e.g., Play Store™) or directly between two user devices (e.g., smart phones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0052] In some embodiments, the electronic device (200) may omit at least one of the components (e.g., the inner frame (2181a), or the support bracket (260)) or may additionally include other components.
[0053] The interface may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, and / or an audio interface.

[0056] FIGS. 4A and 4B are plan views illustrating a printed circuit board (401) of an electronic device according to various embodiments.
[0057] FIG. 4b is a plan view showing a state in which the shielding member (420) and the socket housing (412) in FIG. 4a are removed.
[0058] Referring to FIGS. 4A and 4B , a printed circuit board (401) (e.g., the board (240) of FIG. 3 ) of an electronic device (e.g., the electronic device (100) of FIG. 1 , the electronic device (200) of FIGS. 2A to 3 ) may include a card socket (410) (e.g., the card socket (2401) of FIG. 3 ). The card socket (410) may be configured to accommodate various cards (e.g., IC cards such as a subscriber identification module (SIM) card and / or a memory (407) card) and electrically connect them with other electrical components of the electronic device. In various embodiments, the card socket (410) may be configured to directly accommodate a card, or to accommodate a card mounted on a member such as a tray. The printed circuit board (401) may include a socket area provided to accommodate the card socket (410), and the card socket (410) may be disposed on the socket area. The socket area may be formed with one or more conductive pads (e.g., signal pads (415) of FIG. 5b) configured to be bonded and electrically connected to the card socket (410) by means such as solder.
[0059] In various embodiments, the card socket (410) can accommodate one or more cards. For example, the card socket (410) can accommodate a memory (407) card and a SIM card, or can accommodate multiple SIM cards.
[0060] In various embodiments, the card socket (410) may include one or more signal terminals (413). The signal terminals (413) may be in electrical contact with the card to transmit and receive electrical signals to and / or transmit the status of the card to an electronic device in the form of electrical signals.
[0061] In various embodiments, the card socket (410) may include a socket body (411) and a socket housing (412) that at least partially surrounds the exterior of the socket body (411). In various embodiments, some of the signal terminals (413) may be positioned at the periphery of the socket body (411). Therefore, when designing the size of the socket housing (412) to secure space inside the electronic device, the signal terminals (413) may be partially exposed to the exterior of the socket housing (412).
[0062] The printed circuit board (401) may include a shielding member (420). The shielding member (420) may include a shielding member (420) (e.g., a shield can) that provides electromagnetic interference (EMI) shielding for various electrical components disposed on the printed circuit board (401), such as a processor (405) (e.g., AP (110) of FIG. 1) and / or memory (407) (e.g., memory (120) of FIG. 1). The shielding member (420) may include a conductive material (e.g., copper, stainless steel, aluminum, and / or a conductive film).
[0063] In various embodiments, the shielding member (420) may be positioned adjacent to the card socket (410), thereby reducing the area of the printed circuit board (401) of the electronic device.
[0064] In various embodiments, the printed circuit board (401) may include a ground pad (421) for the shielding member (420). The ground pad (421) may be a conductor pad formed on the surface of the printed circuit board (401) (e.g., the surface facing the -z direction) such that the shielding member (420) is bonded thereto. The shielding member (420) may be bonded to the ground pad (421) by a bonding means such as solder and fixed on the printed circuit board (401). In addition, the shielding member (420) may be grounded through the ground pad (421) to provide EMI shielding. For example, the shielding member (420) may be bonded to the ground pad (421) by an SMT (surface mount technology) technique such as reflow soldering.
[0065] FIG. 5a is an enlarged view of a printed circuit board (401) according to various embodiments.
[0066] FIG. 5b is an enlarged view of a printed circuit board (401) according to various embodiments.
[0067] FIG. 5c is a cross-sectional perspective view of a printed circuit board (401) according to various embodiments.
[0068] FIG. 5d is a perspective view of a shielding member (420) according to various embodiments.
[0069] FIGS. 5a and 5b are enlarged views of the A portion of FIGS. 4a and 4b, respectively.
[0070] FIG. 5c is a cross-section taken along the B-B direction of FIG. 5a.
[0071] Referring to FIGS. 5A and 5B, the printed circuit board (401) may include a signal pad (415). The signal pad (415) may be a conductive pad formed on the printed circuit board (401) so that a signal terminal (413) is disposed thereon. The signal terminal (413) may be bonded to the signal pad (415) by a bonding means such as solder. In various embodiments, the signal pad (415) may be formed in an area of the printed circuit board (401) where the signal terminal (413) is disposed. In various embodiments, the signal pad (415) may have an area larger than an area of the signal terminal (413) on the printed circuit board (401). For example, the outer boundary of the signal pad (415) may be spaced apart from a bottom surface of the signal terminal (413) that is in contact with the signal pad (415) by a certain distance (e.g., D1 or D2 in the drawing).
[0072] The card socket (410) and the signal terminals (413) (e.g., the first signal terminal (413a) and the second signal terminal (413b)) arranged on the periphery of the signal card socket (410) may be arranged adjacent to the shielding member (420) on the periphery of the card socket (410).
[0073] In various embodiments, the signal pad (415) may be positioned offset relative to the signal terminal (413). The signal pad (415) may be positioned offset in the opposite direction of the shielding member (420) relative to the signal terminal (413). For example, the signal pad (415) may be formed to be larger by a first distance (D1) than the bottom surface of the signal terminal (413) in a direction from the signal terminal (413) toward the shielding member (420) (the -y direction in the drawing), and may be formed to be larger by a second distance (D2) than the bottom surface of the signal terminal (413) in an opposite direction from the signal terminal (413) toward the shielding member (420) (the y direction in the drawing). The first distance may be smaller than the second distance. That is, the signal pad (415) may have a dimension in the direction of the shielding member (420) that is smaller than the dimension in the direction opposite to the shielding member (420).
[0074] The card socket (410) can be placed on the printed circuit board (401) by surface mount technology (SMT), such as reflow soldering. During the reflow soldering process, the alignment of the card socket (410) with respect to the socket area on the printed circuit board (401) can be moved by the surface tension of the solder melted on the conductive pad, thereby being aligned with the socket area. For example, the position of the card socket (410) can be aligned so that the bottom surface of the signal terminal (413) of the card socket (410) of the solder is located inside the signal pad (415). By reducing the dimension of the signal pad (415) with respect to the shielding member (420), the risk of the signal terminal (413) moving toward the shielding member (420) during the reflow soldering process, thereby causing a short circuit, can be reduced.
[0075] Referring to FIGS. 5C and 5D , the shielding member (420) may include at least one opening (420a). The opening (420a) of the shielding member (420) may be a portion formed by cutting out a portion of a side surface (e.g., a side facing the y direction) of the shielding member (420). In various embodiments, the opening (420a) may be formed on a side surface of the shielding member (420) facing the signal terminal (413). In various embodiments, the opening (420a) may be formed by cutting out a portion of the side surface of the shielding member (420) that comes into contact with the printed circuit board (401).
[0076] In various embodiments, the size of the opening (420a) may be determined based on the sizes of the signal terminal (413) and the signal pad (415). For example, the length of the opening (420a) (e.g., the dimension in the x-axis direction) may be such that it does not come into contact with the signal pad (415). For example, the height of the opening (420a) (e.g., the dimension in the -z direction) may be such that it does not come into contact with the first signal terminal (413a) and / or the second signal terminal (413b). In various embodiments, the length of the opening (420a) may be 4 mm to 5 mm. The height of the opening (420a) may be 0.2 mm to 0.4 mm.
[0077] When the shielding member (420) and the card socket (410) are bonded (e.g., reflow soldering) on the printed circuit board (401), there is a risk that the signal terminal (413) may come into contact with the shielding member (420) due to an error in the placement position and / or misalignment, thereby causing a short circuit. By forming an opening (420a) on the side of the shielding member (420) adjacent to the signal terminal (413), the risk of the signal terminal (413) coming into contact with the shielding member (420) can be reduced.
[0078] Referring again to FIG. 5b, a ground pad (421) is placed on the printed circuit board (401) so that the shielding member (420) is bonded and grounded, but the ground pad (421) may not be placed in a portion corresponding to the opening (420a) of the shielding member (420). Accordingly, the risk of the signal terminal (413) being short-circuited with the ground pad (421) can be reduced.
[0079] FIG. 6a is a plan view showing a printed circuit board (401) according to various embodiments.
[0080] FIG. 6b is a side view showing a printed circuit board (401) according to various embodiments.
[0081] FIG. 6c is a circuit diagram of a shift detection circuit (600) according to various embodiments.
[0082] Referring to FIGS. 6A and 6B, the printed circuit board (401) may include a socket housing pad (417). The socket housing pad (417) may be a conductive pad formed on a surface of the printed circuit board (401) such that the socket housing (412) is bonded and fixedly positioned on the printed circuit board (401). In some embodiments, the socket housing pad (417) may be electrically connected to a ground circuit of the electronic device to ground the socket housing (412).
[0083] In various embodiments, the socket housing pad (417) may be positioned to overlap the socket housing (412) in a direction in which the face of the printed circuit board (401) faces (e.g., in the -z direction). For example, the socket housing pad (417) may be positioned within the outer perimeter of the socket housing (412) when viewed in the direction in which the face of the printed circuit board (401) faces (in the -z direction).
[0084] As shown in FIG. 5b, when the card socket (410) is joined to the printed circuit board (401) by reflow soldering in a state where the signal pad (415) is arranged to be offset in the opposite direction (y direction) of the shielding member (420), the card socket (410) may be arranged to be offset in the direction in which the signal pad (415) is offset due to the surface tension of the molten solder. Accordingly, there is a risk that the card socket (410) may protrude outside the housing of the electronic device, or a defect may occur in which a card or tray inserted into the card socket (410) protrudes outside the electronic device. Therefore, as shown in FIGS. 6a and 6b, by positioning the socket housing pad (417) inside the outer boundary of the socket housing (412) so as to overlap with the socket housing (412), the degree to which the card socket (410) deviates from the designed position during reflow soldering can be reduced.
[0085] Referring again to FIGS. 6A to 6C, the printed circuit board (401) may include a guideline (601). The guideline (601) may be formed to be adjacent to the card socket (410). The guideline (601) may be positioned a predetermined distance (e.g., 0.1 mm) from the card socket (410) in each direction (e.g., x direction, -x direction, y direction, and / or -y direction) on the surface of the printed circuit board (401). For example, a first guideline (601a) may be positioned in the -y direction from the card socket (410) in the drawing, a second guideline (601b) may be positioned in the y direction from the card socket (410) in the drawing, a third guideline (601c) may be positioned in the -x direction from the card socket (410) in the drawing, and a fourth guideline (601d) may be positioned in the x direction from the card socket (410) in the drawing.
[0086] In various embodiments, the guideline (601) may be formed to be visually identifiable on the printed circuit board (401). For example, the guideline (601) may be formed by partially removing a coating layer (e.g., a solder mask layer) on the printed circuit board (401) to partially expose the conductor. The guideline (601) may be a reference line for verifying the alignment of the card socket (410) on the printed circuit board (401) by visual inspection or computer vision (e.g., automated optical inspection (AOI)).
[0087] In various embodiments, the guideline (601) may protrude from the printed circuit board. For example, the guideline (601) may be formed by stacking and protruding solder from the printed circuit board (401). As another example, the guideline (601) may include a member, such as a conductive foam gasket, attached to the printed circuit board (401).
[0088] In various embodiments, the guide (601) may be connected to a detection circuit. The detection circuit may be configured to change an electrical state when the card socket (410) and the guide (601) are in electrical contact. For example, the detection circuit may include a voltage source (602) that forms a predetermined potential difference, and the voltage source (602) may be electrically connected to the guide (601) and a processor (605) of the electronic device (e.g., AP (110) of FIG. 1, processor (405) of FIG. 4B). For example, the detection circuit may be electrically connected to a GPIO port of the processor (405). The detection circuit may also include other electrical components (e.g., resistors (603), inductors, capacitors) for overcurrent limiting and / or impedance matching.
[0089] When the card socket (410) is displaced from its original position, the socket housing (412) connected to the grounding electrode (604) comes into contact with at least one of the guidelines (601), and thus a conductive path can be formed from the voltage source (602) to the socket housing (412) through the guidelines (601). Accordingly, the electrical state of the processor (405) connected to the guidelines (601) of the detection circuit changes, and thereby an alignment defect of the card socket (410) can be detected.
