Description

Electronic device including interposer

Various embodiments disclosed in this document relate to an electronic device including an interposer.

Electronic devices are becoming increasingly slimmer and are being developed in the direction of increasing the rigidity of electronic devices. For example, it may be important for electronic devices to have a robust structure that can ensure effective electrical connection between electronic components placed inside and maintain electrical connection between electronic components even under external impact.

An electronic device may include at least one electronic component arranged in an internal space. The at least one electronic component may be electrically connected to each other to perform a function of the electronic device. The electronic component may include at least two printed circuit boards arranged in an internal space of the electronic device. Each printed circuit board may be arranged in a manner of being stacked on top of each other to secure an efficient mounting space, and may be electrically connected to each other by an interposer arranged therebetween. For example, each printed circuit board may include a plurality of conductive terminals, and the two printed circuit boards may be electrically connected by physically contacting a plurality of corresponding conductive terminals arranged on corresponding surfaces of the interposer.

A substrate structure including a plurality of printed circuit boards and an interposer may be arranged adjacent to a side of a housing in terms of the arrangement structure of an electronic device. At least one of the plurality of printed circuit boards may be formed to protrude toward one side (e.g., a side) of the housing with respect to the interposer or another printed circuit board, thereby supporting the substrate structure with respect to the housing. However, when an external impact is applied to the electronic device, a portion of the plurality of printed circuit boards that protrudes toward one side of the housing may be damaged due to a concentrated external force.

Meanwhile, a liquid heat-dissipating material (e.g., TIM; thermal interface material) may be filled between the plurality of printed circuit boards. A hole for inserting the liquid heat-dissipating material may be formed in at least one of the plurality of printed circuit boards. When a hole for inserting the heat-dissipating material is formed, the placement area of electronic components that may be placed on the printed circuit board may be reduced.

According to one embodiment of the present disclosure, an electronic device includes a housing including a front surface, a back surface opposite the front surface, and a side surface surrounding a space between the front surface and the back surface, a first printed circuit board disposed in the housing and including a first conductive terminal, a second printed circuit board disposed parallel to the first printed circuit board and including a second conductive terminal, an interposer disposed between the first printed circuit board and the second printed circuit board and including a first conductive pad connected to the first conductive terminal and a second conductive pad connected to the second conductive terminal, and a guide member disposed on one surface of the interposer, wherein the guide member can further protrude with respect to one end of the first printed circuit board and one end of the second printed circuit board.

An electronic device according to one embodiment of the present disclosure includes a housing including a front surface, a back surface opposite the front surface, and a side surface surrounding a space between the front surface and the back surface, a first printed circuit board disposed in the housing and including a first conductive terminal, a second printed circuit board disposed parallel to the first printed circuit board and including a second conductive terminal, an interposer disposed between the first printed circuit board and the second printed circuit board and including a first conductive pad connected to the first conductive terminal and a second conductive pad connected to the second conductive terminal, and a guide member including a first support portion disposed on one surface of the interposer and a second support portion bent from the first support portion and disposed on one surface of the second printed circuit board on which the second conductive terminal is disposed, wherein one of one end of the first printed circuit board and one end of the second printed circuit board may further protrude with respect to the other of the one end of the first printed circuit board and the one end of the second printed circuit board and the guide member.

According to one embodiment disclosed in the present document, a guide member may be arranged on one side of an interposer. The guide member may further protrude toward one side (e.g., a side) of a housing with respect to a plurality of printed circuit boards, thereby supporting a substrate structure including a plurality of printed circuit boards and the interposer with respect to the housing. Since the guide member is formed of a material having a certain level of rigidity, even if an external impact of an electronic device is applied and the housing and the guide member collide, the guide member may not be damaged.

According to one embodiment disclosed in the present document, a separate hole for inserting a heat dissipation member can be formed in the guide member. Accordingly, the area on which electronic components can be placed can be expanded since a plurality of printed circuit boards do not have holes formed for inserting a heat dissipation member.

The camera modules (205, 212) may include one or more lenses, an image sensor, and/or an image signal processor. The flash (213) may include, for example, a light emitting diode or a xenon lamp. In some embodiments, two or more lenses (a wide-angle lens, an ultra-wide-angle lens, or a telephoto lens) and image sensors may be disposed on one side of the electronic device (200).

The key input device (217) may be positioned on a side surface (210C) of the housing (210). In one embodiment, the electronic device (200) may not include some or all of the above-mentioned key input devices (217), and the key input devices (217) that are not included may be implemented in other forms, such as soft keys, on the display (201). In one embodiment, the key input device (217) may be implemented using a pressure sensor included in the display (201).

The indicator may be disposed, for example, on the first side (210A) of the housing (210). The indicator may provide, for example, status information of the electronic device (200) in the form of light (e.g., a light-emitting element). In one embodiment, the light-emitting element may provide, for example, a light source that is linked to the operation of the camera module (205). The indicator may include, for example, an LED, an IR LED, and/or a xenon lamp.

Such a transparent area may include an area that overlaps with an effective area (e.g., a field of view area) of the camera module (205) through which light passes to be imaged by the image sensor to create an image. For example, the transparent area of the display (201) may include an area having a lower pixel density than the surrounding area. For example, the transparent area may replace the opening. For example, the camera module (205) may include an under display camera (UDC). In one embodiment, some of the sensor modules (204) may be arranged to perform their functions without being visually exposed through the front plate (202) in the internal space of the electronic device. For example, in such a case, the area of the display (201) that faces the sensor module may not require a perforated opening.

According to various embodiments, the electronic device (400) may include an interposer (440) interposed between a first printed circuit board (420) and a second printed circuit board (430). According to one embodiment, the interposer (440) may include a plurality of conductive pads and may electrically connect the two printed circuit boards (420, 430) by physically contacting conductive terminals disposed on the two printed circuit boards (420, 430) through pre-solder. For example, the interposer (440) may be preferentially disposed on the first printed circuit board (420) through pre-solder applied to the first conductive pad. In another embodiment, the interposer (440) may be preferentially disposed on the second printed circuit board (430) through pre-solder applied to the second conductive pad. According to one embodiment, the electronic device (400) may include a second support member (450) disposed between the second printed circuit board (430) and the rear cover (480).

For example, the first printed circuit board (420), the interposer (440), and the second printed circuit board (430) may be fixed to the first support member (411) through the second support member (450) disposed thereon. For example, the second support member (450) may be fixed to the first support member (411) through a fastening member such as a screw, thereby firmly supporting an electrical connection between the first printed circuit board (420), the interposer (440), and the second printed circuit board (430).

Below, the interposer (440) will be described in detail.

FIG. 5a is a perspective view of an interposer according to various embodiments of the present invention. FIG. 5b is a partial cross-sectional view illustrating the configuration and bonding state between an interposer and printed circuit boards according to various embodiments of the present invention.

Referring to FIG. 5A, the interposer (440) may include a dielectric substrate (441) including a first surface (4401) facing in a first direction (① direction) (e.g., + Z direction of FIG. 5A) and a second surface (4402) facing in a direction (② direction) opposite to the first surface (4401) (e.g., - Z direction of FIG. 5A). According to one embodiment, the interposer (440) may include a plurality of conductive pads (442, 443) (e.g., first conductive pad (442) and second conductive pad (443) of FIG. 5B) that are arranged at regular or irregular intervals on the first surface (4401) and the second surface (4402) and are exposed to the outside. According to one embodiment, the plurality of conductive pads (442, 443) may have different sizes and may be arranged at regular or irregular intervals. For example, at least one conductive pad connected to the ground among the plurality of conductive pads (442, 443) may be formed larger than at least one conductive pad used for signal transmission. According to one embodiment, the plurality of conductive pads (442, 443) may be electrically connected through a conductive post (e.g., a conductive post (444) of FIG. 5B) (e.g., a conductive via) that penetrates from the first surface (4401) to the second surface (4402) of the dielectric substrate (441).

In one embodiment, the interposer (440) can include at least one screw fastening portion (4411) that is at least partially disposed. In one embodiment, the interposer (440) can be secured to at least one support structure (e.g., the first support member (411) and/or the second support member (450) of FIG. 4) disposed inside an electronic device (e.g., the electronic device (400) of FIG. 4) via the screw fastening portion (4411).

According to one embodiment, the interposer (440) may have a shape substantially identical to at least one of the first printed circuit board (e.g., the first printed circuit board (420) of FIG. 4) or the second printed circuit board (e.g., the second printed circuit board (430) of FIG. 4)) and may include a first opening (4404) formed in the center. In one embodiment, the interposer (440) may be formed in a loop shape including the first opening (4404). In another embodiment, the interposer (440) may be formed in a shape at least partially different from at least one of the first printed circuit board (e.g., the first printed circuit board (420) of FIG. 4) or the second printed circuit board (e.g., the second printed circuit board (430) of FIG. 4). According to one embodiment, the first opening (4404) can be utilized as an accommodation space for accommodating electronic components (e.g., various electrical components (e.g., electrical components (P) of FIG. 8A) or shield cans) arranged on at least one of the two printed circuit boards (420, 430).

According to one embodiment, as illustrated in FIG. 5b, an electronic device (e.g., an electronic device (400) of FIG. 4) may include a first printed circuit board (420) disposed in an internal space and including a plurality of first conductive terminals (421), a second printed circuit board (430) disposed substantially parallel to the first printed circuit board (420) and including a second plurality of conductive terminals (431), and an interposer (440) disposed between the first printed circuit board (420) and the second printed circuit board (430) to electrically connect the first printed circuit board (420) and the second printed circuit board (430).

In one embodiment, the interposer (440) may include a dielectric substrate (441) having a first side (4401) facing a first printed circuit board (420) (e.g., a main board) and a second side (4402) facing in an opposite direction from the first side (4401) and facing a second printed circuit board (430) (e.g., a sub board). In one embodiment, the interposer (440) may include a first conductive pad (442) disposed on the first side (4401) of the dielectric substrate (4401) to face a first conductive terminal (421) disposed on one side of the first printed circuit board (420). In one embodiment, the interposer (440) may include a second conductive pad (443) disposed on a second side (4402) of the dielectric substrate (441) so as to face a second conductive terminal (431) disposed on one side of the second printed circuit board (430).

In one embodiment, the first conductive pad (442) and the second conductive pad (443) can be electrically connected via a conductive post (444) (e.g., a conductive via) positioned to penetrate from the first surface (4401) to the second surface (4402) of the dielectric substrate (441). In one embodiment, the interposer (440) can include a pre-solder (PS) positioned such that the first conductive pad (442) is electrically and physically connected to the first conductive terminal (421) of the first printed circuit board (420) and the second conductive pad (443) is electrically and physically connected to the second conductive terminal (431). According to one embodiment, the pre-solder (PS) can connect the respective terminals to each other through a reflow process when the first printed circuit board (420) and the second printed circuit board (430) are connected to the interposer (440). In one embodiment, the reflow process may be a process for soldering to a substrate (e.g., the first printed circuit board (420) or the second printed circuit board (430)) by supplying solder in advance to a land of the substrate (e.g., the first printed circuit board (420) or the second printed circuit board (430)) and melting the solder with an external heat source to connect the land. In one embodiment, the soldering process is not limited to reflow soldering, and various methods such as flow soldering other than reflow soldering may be used.

In one embodiment, referring to FIG. 5A, the interposer (440) may include a second opening (501). In one embodiment, the second opening (501) of the interposer (440) may be an area from which a portion of the interposer (440) has been removed. In one embodiment, the second opening (501) of the interposer (440) may be formed on one side of the interposer (440) formed in a loop shape and may be connected to a first opening (4404) located inside the loop formed by the interposer (440).

The guide member (510) to be described below may be placed on one side of the interposer (440) to cover the second opening (501). The coupling relationship between the interposer (440) and the guide member (510) will be described in detail below.

FIG. 6 is a perspective view of a laminated structure of a first printed circuit board, an interposer, and a second printed circuit board according to an embodiment of the present disclosure. FIG. 7a is a perspective view of a guide member according to an embodiment of the present disclosure. FIGS. 7b and 7c are drawings explaining the coupling of the guide member and the interposer of FIG. 7a. FIG. 7d is a drawing explaining a conductive plate electrically connecting a conductive pad of the interposer and the guide member. FIG. 8a is a cross-sectional view taken along the line A-A of FIG. 6 in a state where the guide member of FIG. 7a is coupled with the interposer. FIG. 8b is a drawing showing a state in which the first printed circuit board, the interposer, and the second printed circuit board are laminated as seen in the -X direction of FIG.

According to one embodiment, an interposer (440) may be disposed between a first printed circuit board (420) and a second printed circuit board (430) to electrically connect the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, a first conductive terminal (421) of the first printed circuit board (420) may be electrically connected to a first conductive pad (442) of the interposer (440) through a pre-solder (PS). A second conductive terminal (431) of the second printed circuit board (430) may be electrically connected to a second conductive pad (443) of the interposer (440) through a pre-solder (PS). Accordingly, the first printed circuit board (420) and the second printed circuit board (430) may be electrically connected through the interposer (440).

According to one embodiment, as illustrated in FIG. 6, the interposer (440) may include a first surface (4401) facing a first conductive terminal (421) disposed on one surface of a first printed circuit board (420) (e.g., a first surface (4401) of a dielectric substrate (4401)), a second surface (4402) facing a second conductive terminal (431) disposed on one surface of a second printed circuit board (430) (e.g., a second surface (4402) of a dielectric substrate (4401) (4402)), and a third surface (4403) surrounding a space between the first surface (4401) and the second surface (4402). In one embodiment, the guide member (510) may be disposed on the third side (4403) of the interposer (440) to face a mechanism adjacent to the first printed circuit board (420) and the second printed circuit board (430). For example, the guide member (510) may face one side of a support member (e.g., the first support member (411) of FIG. 4 ) adjacent to the first printed circuit board (420) and the second printed circuit board (430) and/or a side surface (210C) of the housing (210). In one embodiment, the guide member (510) may face a side surface member (410) disposed in the housing (210) (e.g., the side surface member (310) of FIG. 3 ). For convenience of explanation, the following description will be made on the assumption that the guide member (510) faces the side surface (210C) of the housing (210). However, as described above, the guide member (510) may face one side of the support member (e.g., the first support member (411)), the bracket, or the side member (410) on which the first printed circuit board (420) and the second printed circuit board (430) are placed.

In one embodiment, the guide member (510) may be disposed on the third side (4403) of the interposer (440) to protrude further than the first printed circuit board (420) disposed on the first side (4401) of the interposer (440) and the second printed circuit board (430) disposed on the second side (4402) of the interposer (440). For example, the guide member (510) may protrude in the −X direction with respect to FIG. 6 toward a mechanism (e.g., a support member, a bracket, a housing (210)) on which the first printed circuit board (420) and the second printed circuit board (430) are disposed. In one embodiment, the guide member (510) may be formed of a material having a certain level of rigidity. For example, the guide member (510) may be formed of a metal material having a certain level of rigidity and electrical conductivity, such as aluminum (Al), iron (Fe), or copper (Cu). Accordingly, when an external impact (e.g., dropping) is applied to the electronic device (400), the guide member (510) may come into contact with the side surface (210C) of the housing (210) or the support member (e.g., the first support member (411) of FIG. 4) to alleviate the impact applied to the laminated structure of the first printed circuit board (420) - interposer (440) - second printed circuit board (430).

According to one embodiment, the first printed circuit board (420) and the second printed circuit board (430) on which a plurality of electronic components (P) are arranged may generate heat. In one embodiment, a heat dissipation member may be arranged between the first printed circuit board (420) and the second printed circuit board (430). For example, the heat dissipation member may be a thermal interface material (TIM) having excellent heat conduction efficiency, and may also mean various thermally conductive materials having excellent heat conductivity.

In one embodiment not shown in the drawing, an insertion hole (e.g., an insertion hole (514) of FIG. 7A, an insertion hole (614) of FIG. 9A) into which a liquid heat dissipation material (not shown) can be injected may be formed in at least one of the first printed circuit board (420), the second printed circuit board (430), and the interposer (440). In one embodiment, an insertion hole into which a liquid heat dissipation material can be injected may be formed in a third surface (4403) of the interposer (440). For example, a guide material (510) may be arranged in the third surface (4403) of the interposer (440), and separately, an insertion hole into which a heat dissipation material is injected may be formed in a portion where the guide material (510) is not arranged. A nozzle (N) connected to a device including a heat dissipation member can be inserted into the insertion hole to emit the heat dissipation member between the first printed circuit board (420) and the second printed circuit board (430). Accordingly, the heat dissipation member can be filled between the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, when an insertion hole is formed in any one of the first printed circuit board (420), the second printed circuit board (430), or the interposer (440), a separate flexible member (e.g., a flexible member (540) of FIG. 8B) can be placed in the insertion hole so that the heat dissipation member filled between the first printed circuit board (420) and the second printed circuit board (430) does not flow to the outside through the insertion hole. For example, a flexible member (540) covering the insertion hole can be placed on a third surface (4403) of the interposer (440). The flexible member (540) may include a plurality of cutting portions (541). When a nozzle (N) for emitting a heat dissipation member is inserted into the insertion hole, the flexible member (540) may allow the nozzle (N) to be inserted into the first opening (4404) of the interposer (440) by bending the plurality of cutting portions (541) in the insertion direction of the nozzle (N), and may block the insertion hole of the interposer (440) while the nozzle (N) is not inserted.

In one embodiment, the interposer (440) may include a second opening (501), which is a space into which a nozzle (N) for emitting a heat dissipation member is inserted. In one embodiment, referring to FIGS. 5A and 7B, the second opening (501) may be a space formed by removing at least a portion of the interposer (440). In one embodiment, the guide member (510) may be disposed on the third surface (4403) of the interposer (440) to cover at least a portion of the second opening (501). The guide member (510) may include an insertion hole (514) connected to the second opening (501). In one embodiment, the insertion hole (514) may be formed to have a smaller size than the second opening (501). In one embodiment, the size of the insertion hole (514) may be formed such that the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) does not flow out of the interposer (440). Accordingly, as will be described later, the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) can be prevented from being released out of the interposer (440) through the insertion hole (514).

In one embodiment not shown in the drawing, the second opening (501) may be a hole formed in the third surface (4403) of the interposer (440). In one embodiment, the second opening (501) of the interposer (440) and the insertion hole (514) of the guide member (510) may be formed to have substantially the same size. Alternatively, in one embodiment, the insertion hole (514) of the guide member (510) may be formed to have a smaller size than the second opening (501) of the interposer (440). Accordingly, as will be described later, it is possible to prevent the heat dissipation member filled between the first printed circuit board (420) and the second printed circuit board (430) from being released to the outside of the interposer (440) through the insertion hole (514).

In one embodiment, referring to FIGS. 7A, 7B, and 7C, the guide member (510) may include a body (511) disposed on one surface (e.g., the third surface (4403)) of the interposer (440), a first cut portion (512) bent relative to the body (511) to face the first printed circuit board (420), and a second cut portion (513) bent relative to the body (511) to face the second printed circuit board (430). In one embodiment, a second opening (501) may be formed in the body (511) of the guide member (510). In one embodiment, referring to FIG. 8A described below, the first section (512) of the guide member (510) may be positioned at least partially in the second opening (501) of the interposer (440) to contact the first conductive terminal (421) of the first printed circuit board (420). The second section (513) of the guide member (510) may be positioned at least partially in the second opening (501) of the interposer (440) to contact the second conductive terminal (431) of the second printed circuit board (430). Accordingly, the guide member (510) may electrically connect the first printed circuit board (420) and the second printed circuit board (430).

In one embodiment, the guide member (510) can be secured to the third face (4403) of the interposer (440) in various ways. In one embodiment, referring to FIGS. 7b and 7c, the guide member (510) can be secured to the interposer (440) via an adhesive member (530) disposed between the body (511) and the third face (4403) of the interposer (440).

In one embodiment, the adhesive member (530) may be formed of a conductive material and may serve as a passage for transmitting a signal transmitted from the first printed circuit board (420) or the second printed circuit board (430) to the guide member (510). In one embodiment, the adhesive member (530) may be in contact with the first conductive pad (442) and the second conductive pad (443) of the interposer (440). Accordingly, an electrical signal generated from the first printed circuit board (420) may be transmitted to the second printed circuit board (430) via the interposer (440) - the adhesive member (530) - the guide member (510). In addition, an electrical signal generated from the second printed circuit board (430) may be transmitted to the first printed circuit board (420) via the interposer (440) - the adhesive member (530) - the guide member (510).

In one embodiment, a conductive plate formed of a conductive material may be disposed on the first side (4401) and/or the second side (4402) of the interposer (440). In one embodiment, the conductive plate may include a first conductive plate (521) disposed on the first side (4401) of the interposer (440) and a second conductive plate (not shown) disposed on the second side (4402). In one embodiment, referring to FIG. 7d, the first conductive plate (521) may be disposed on the first side (4401) of the interposer (440) to cover the first section (512) of the guide member (510). In one embodiment not shown in the drawing, the second conductive plate may be disposed on the second side (4402) of the interposer (440) to cover the second section (513) of the guide member (510). Accordingly, the conductive plates can be placed on the first side (4401) and the second side (4402) of the interposer (440) to secure the guide member (510) to the interposer (440).

In one embodiment, the conductive plate can electrically connect the first printed circuit board (420) - the guide member (510) - the second printed circuit board (430). In one embodiment, the first conductive plate (521) can be in contact with at least one of the first conductive terminal (421) of the first printed circuit board (420) and the first conductive pad (442) of the interposer (440). The second conductive plate can be in contact with at least one of the second conductive terminal (431) of the second printed circuit board (430) and the second conductive pad (443) of the interposer (440). In one embodiment, when the first conductive plate (521) is in contact with the first conductive terminal (421) of the first printed circuit board (420) and the second conductive plate is in contact with the second conductive terminal (431) of the second printed circuit board (430), a conductive path can be formed that connects the first printed circuit board (420) - the first conductive plate (521) - the guide member (510) - the second conductive plate - the second printed circuit board (430). In one embodiment, when the first conductive plate (521) is in contact with the first conductive pad (442) of the interposer (440) and the second conductive plate is in contact with the second conductive pad (443) of the interposer (440), an electrical signal transmitted from the first printed circuit board (420) to the interposer (440) may be transmitted to the second printed circuit board (430) through the first conductive plate (521) - the guide member (510) - the second conductive plate. For example, an electrical signal transmitted from the second printed circuit board (430) to the interposer (440) may be transmitted to the first printed circuit board (420) through the second conductive plate - the guide member (510) - the first conductive plate (521). Accordingly, the first printed circuit board (420) and the second printed circuit board (430) can be electrically connected through the guide member (510) and the conductive plate.

According to one embodiment, referring to FIGS. 7A, 7B, and 8A, the guide member (510) may include an insertion hole (514) connected to the second opening (501) of the interposer (440). In one embodiment, the insertion hole (514) may be formed in the body (511) of the guide member (510) located on the third surface (4403) of the interposer (440). In one embodiment, the insertion hole (514) may guide the nozzle (N) so that the nozzle (N) may be inserted into the second opening (501) of the interposer (440). The nozzle (N) may sequentially discharge the heat dissipation member between the first printed circuit board (420) and the second printed circuit board (430) through the insertion hole (514) of the guide member (510) and the second opening (501) of the interposer (440).

In one embodiment, referring to FIGS. 8A and 8B, a flexible member (540) covering an insertion hole (514) may be arranged on the guide member (510). In one embodiment, the flexible member (540) may be arranged on a body (511) of the guide member (510). In one embodiment, the flexible member (540) may be arranged on a back surface of the guide member (510) (e.g., a surface facing the + X direction with respect to FIG. 8A). In one embodiment not illustrated in the drawings, the flexible member (540) may be arranged on a front surface of the guide member (510) (e.g., a surface facing the - X direction with respect to FIG. 8A). In one embodiment, the flexible member (540) may have a plurality of cut portions (541) that can be bent in the insertion direction of the nozzle (N) (e.g., + X direction with reference to FIG. 8A) when a nozzle (N) emitting a heat dissipation member is inserted into the insertion hole (514) to allow the nozzle (N) to be inserted into the first opening (4404) of the interposer (440), and block the insertion hole (514) while the nozzle (N) is not inserted.

In one embodiment, the interposer (440) may include an opening other than the second opening (501). In one embodiment, the interposer (440) may include a third opening (not shown) (e.g., an inspection hole) for inspecting whether a liquid heat dissipation member is inserted between the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, the third opening may be formed in the interposer (440) so as to face the second opening (501) through which a nozzle (N) for emitting the heat dissipation member is inserted. The inspector can check the degree of insertion of the heat dissipation member flowing into the second opening (501) through the third opening, and check the degree of filling of the heat dissipation member between the first printed circuit board (420) and the second printed circuit board (430). Additionally, the interposer (440) may include a fourth opening (e.g., a vent hole) (not shown) for dissipating heat transferred from the first printed circuit board (420) and the second printed circuit board (430) to the heat dissipation member.

Fig. 9a is a perspective view of a guide member different from Fig. 7a. Fig. 9b is a drawing explaining the combination of the guide member of Fig. 9a and the interposer. Fig. 10a is a cross-sectional view taken along the line A-A of Fig. 6, showing the guide member of Fig. 9a combined with the interposer. Fig. 10b is a drawing showing the first printed circuit board, the interposer, and the second printed circuit board stacked in the -X direction of Fig. 10a.

Hereinafter, a guide member (610) of another embodiment will be described in addition to the guide member (510) described in FIGS. 7a to 8b. Duplicate descriptions of components that are identical or similar to those described above will be omitted.

According to one embodiment, as illustrated in FIGS. 9A, 9B, and 10A, the guide member (610) (e.g., the guide member (510) of FIG. 7A) may be formed of a conductive material to electrically connect the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, the guide member (610) may include a body (611) disposed on one surface (e.g., the third surface (4403)) of the interposer (440), a first cut portion (612) bent relative to the body (611) to face the first printed circuit board (420), and a second cut portion (613) bent relative to the body (611) to face the second printed circuit board (430). In one embodiment, referring to FIG. 10a described below, the first section (612) may be positioned at least partially between the first printed circuit board (420) and the interposer (440). The second section (613) may be positioned at least partially between the second printed circuit board (430) and the interposer (440).

In one embodiment, the guide member (610) may protrude from a first printed circuit board (420) disposed on a first surface (4401) of the interposer (440) and a second printed circuit board (430) disposed on a second surface (4402) of the interposer (440) such that at least a portion (e.g., the body (611)) of the guide member (610) is disposed on the third surface (4403) of the interposer (440). For example, the body (611) of the guide member (610) may protrude in the −X direction with respect to one end of the first printed circuit board (420) and one end of the second printed circuit board (430) with respect to FIG. 10A toward a mechanism (e.g., the first support member (411), the housing (210)) on which the first printed circuit board (420) and the second printed circuit board (430) are disposed. Accordingly, when an external impact (e.g., dropping) is applied to the electronic device (400), the body (611) of the guide member (610) comes into contact with the mechanism (e.g., the first support member (411) and/or the housing (210)) on which the first printed circuit board (420) and the second printed circuit board (430) are placed, thereby alleviating the impact applied to the laminated structure of the first printed circuit board (420) - interposer (440) - second printed circuit board (430).

In one embodiment, the guide member (610) can be secured to the interposer (440), the first printed circuit board (420), the second printed circuit board (430), and the interposer (440) in various ways. In one embodiment, the guide member (610) can be secured to the interposer (440) via an adhesive member disposed between the body (611) and the third side (4403) of the interposer (440). In one embodiment, the first printed circuit board (420) can include a first mounting groove (not shown) in which the first cut portion (612) of the guide member (610) can be secured. For example, the second printed circuit board (430) can include a second mounting groove (not shown) in which the second cut portion (613) of the guide member (610) can be secured.

According to one embodiment, as illustrated in FIG. 9b, the first cut portion (612) and the second cut portion (613) of the guide member (610) may be positioned between the printed circuit board (420, 430) and the interposer (440). In one embodiment, the first cut portion (612) may be in contact with at least one of the first conductive terminal (421) of the first printed circuit board (420) and the first conductive pad (442) of the interposer (440). The second cut portion (613) may be in contact with at least one of the second conductive terminal (431) of the second printed circuit board (430) and the second conductive pad (443) of the interposer (440). For example, the guide member (610) can electrically connect the first printed circuit board (420) and the second printed circuit board (430) as the first cut portion (612) comes into contact with the first conductive terminal (421) and/or the first conductive pad (442) and the second cut portion (613) comes into contact with the second conductive terminal (431) and/or the second conductive pad (443). In one embodiment, as the first cut portion (612) of the guide member (610) comes into contact with the first conductive terminal (421) and the second cut portion (613) comes into contact with the second conductive terminal (431), a conductive path connecting the first printed circuit board (420) - the guide member (610) - the second printed circuit board (430) can be formed. In one embodiment, when the first section (612) is in contact with the first conductive pad (442) and the second section (613) is in contact with the second conductive pad (443), an electrical signal transmitted from the first printed circuit board (420) to the interposer (440) can be transmitted to the second printed circuit board (430) through the first section (612) of the guide member (610) - the body (611) of the guide member (610) - the second section (613) of the guide member (610). For example, an electrical signal transmitted from the second printed circuit board (430) to the interposer (440) can be transmitted to the first printed circuit board (420) through the second section (613) of the guide member (610) - the body (611) of the guide member (610) - the first section (612) of the guide member (610). Accordingly, the first printed circuit board (420) and the second printed circuit board (430) can be electrically connected through the guide member (610).

According to one embodiment, the guide member (610) may include an insertion hole (614) connected to the second opening (501) of the interposer (440), as illustrated in FIGS. 9A and 9B and FIG. 10A. In one embodiment, the insertion hole (614) may be formed in the body (611) of the guide member (610) located on the third surface (4403) of the interposer (440). In one embodiment, the insertion hole (614) may guide the nozzle (N) so that the nozzle (N) may be inserted into the second opening (501) of the interposer (440). The nozzle (N) may sequentially discharge the heat dissipation member between the first printed circuit board (420) and the second printed circuit board (430) through the insertion hole (614) of the guide member (610) and the second opening (501) of the interposer (440).

In one embodiment, the insertion hole (614) may be formed to have a smaller size than the second opening (501). In one embodiment, the size of the insertion hole (614) may be formed to such a size that the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) does not flow out of the interposer (440). For example, the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) may be prevented from being discharged out of the interposer (440) through the insertion hole (614). In one embodiment not shown in the drawing, the second opening (501) may be formed in a hole shape on the third surface (4403) of the interposer (440). In one embodiment, the second opening (501) of the interposer (440) and the insertion hole (614) of the guide member (610) may be formed to have substantially the same size. Alternatively, in one embodiment, the insertion hole (614) of the guide member (610) may be formed to have a smaller size than the second opening (501) of the interposer (440). Accordingly, the heat dissipation member filled between the first printed circuit board (420) and the second printed circuit board (430) may be prevented from being released to the outside of the interposer (440) through the insertion hole (614).

According to one embodiment, as illustrated in FIGS. 10A and 10B, a flexible member (540) covering an insertion hole (614) may be disposed on the guide member (610). In one embodiment, the flexible member (540) may be disposed on a body (611) of the guide member (610). In one embodiment, the flexible member (540) may be disposed on a back surface (e.g., a surface facing the +X direction with respect to FIG. 10A) of the guide member (610). In one embodiment not illustrated in the drawings, the flexible member (540) may be disposed on a front surface (e.g., a surface facing the -X direction with respect to FIG. 10A) of the guide member (610). In one embodiment, the flexible member (540) may have a plurality of cut portions (e.g., cut portions (541) of FIG. 8b) that may be bent in the insertion direction of the nozzle (N) (e.g., + X direction based on FIG. 10a) when a nozzle (N) that emits a heat dissipation member is inserted into the insertion hole (614) to allow the nozzle (N) to be inserted into the first opening (4404) of the interposer (440), and may block the insertion hole (614) while the nozzle (N) is not inserted.

FIG. 11a is a cross-sectional view of an embodiment in which a guide member different from that of FIGS. 7a and 9a is arranged on an interposer, a first printed circuit board, and a second printed circuit board. FIG. 11b is a drawing showing a state in which the first printed circuit board, the interposer, and the second printed circuit board are stacked as viewed in the -X direction of FIG. 11a.

Hereinafter, a guide member (710) of another embodiment will be described in relation to the guide member described in FIGS. 7A to 10B (e.g., the guide member (510) of FIG. 7A, the guide member (610) of FIG. 9A). Duplicate descriptions of components that are identical or similar to those described above will be omitted.

In one embodiment, one end of the first printed circuit board (420) and one end of the second printed circuit board (430) may further protrude toward a mechanism adjacent to the first printed circuit board (420) and the second printed circuit board (430) relative to the other. In one embodiment, one end of the first printed circuit board (420) and one end of the second printed circuit board (430) may further protrude toward a support member (e.g., the first support member (411)) on which the first printed circuit board (420) and the second printed circuit board (430) are disposed and/or a side surface (210C) of the housing (210) relative to the other. In the following description, for convenience of explanation, it is assumed that the mechanism facing one end of the first printed circuit board (420) and one end of the second printed circuit board (430) is the side surface (210C) of the housing (210), and that one end of the first printed circuit board (420) and one end of the second printed circuit board (430) protrudes toward the side surface (210C) of the housing (210) relative to the other.

In one embodiment, referring to FIG. 11A, one end of the second printed circuit board (430) may further protrude toward the side surface (210C) of the housing (210) with respect to one end of the first printed circuit board (420). In one embodiment not illustrated in the drawing, one end of the first printed circuit board (420) may further protrude toward the side surface (210C) of the housing (210) with respect to one end of the second printed circuit board (430). In this case, when an external impact is applied to the electronic device (400), the portion of one end of the first printed circuit board (420) and one end of the second printed circuit board (430) that protrudes toward the side surface (210C) of the housing (210) may be supported through the housing (210), thereby alleviating the impact applied to the first printed circuit board (420), the second printed circuit board (430), and the interposer (440). For convenience of explanation, in the following description, it is assumed that one end of the second printed circuit board (430) protrudes further toward the side surface (210C) of the housing (210) than one end of the first printed circuit board (420).

In one embodiment, one end of the second printed circuit board (430) facing the side surface (210C) of the housing (210) may be plated with a metal material. In this case, the rigidity of one end of the second printed circuit board (430) may be reinforced through the plating. Accordingly, damage that may occur when an external impact is applied to the electronic device (400) and one end of the second printed circuit board (430) comes into contact with the side surface (210C) of the housing (210) may be prevented or reduced.

According to one embodiment, as illustrated in FIGS. 11A and 11B, the guide member (710) may be at least partially disposed on the first printed circuit board (420) and the second printed circuit board (430) to increase the bonding force between the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, the guide member (710) may include a first support member (711) disposed on a third surface (4403) of the interposer (440), a second support member (712) bent from the first support member (711) and disposed on one surface of the second printed circuit board (430), and a third support member (713) bent from the first support member (711) and disposed on one surface of the first printed circuit board (420). In one embodiment, the second support member (712) may be coupled with a surface on which the second conductive terminal (431) of the second printed circuit board (430) is arranged. In one embodiment, the third support member (713) may be coupled with a surface on which the first conductive terminal (421) of the first printed circuit board (420) is arranged or an opposite surface. Since the second printed circuit board (430) is coupled with the first printed circuit board (420) through the guide member (710), when an external impact is applied to the electronic device (400) and one end of the second printed circuit board (430) comes into contact with the housing (210), the impact may be dispersed. In addition, since the second printed circuit board (430) is fixed to the first printed circuit board (420) through the guide member (710), even if it collides with the housing (210), a buckling or bending phenomenon may be improved or reduced.

According to one embodiment, the guide member (710) can be fixed to the interposer (440), the first printed circuit board (420), the second printed circuit board (430), and the interposer (440) in various ways. In one embodiment, the first support member (711) of the guide member (710) can be fixed to the third surface (4403) of the interposer (440) via an adhesive member. The second support member (712) can be positioned and fixed in a second fixing groove formed on one surface of the second printed circuit board (430). The third support member (713) can be positioned and fixed in a first fixing groove formed on one surface of the first printed circuit board (420).

In one embodiment, the guide member (710) can electrically connect the first printed circuit board (420) and the second printed circuit board (430). In one embodiment, referring to FIG. 11A, the second support member (712) and the third support member (713) of the guide member (710) can be disposed on the second printed circuit board (430) and the first printed circuit board (420), respectively. In one embodiment, the second support member (712) can be in contact with the second conductive terminal (431) of the second printed circuit board (430). In one embodiment not shown in the drawing, the third support member (713) can be electrically connected to the first conductive terminal (421) of the first printed circuit board (420). In one embodiment, referring to FIG. 11A, the third support member (713) may be disposed on an opposite surface of the first printed circuit board (420) on which the first conductive terminal (421) is disposed, and may be electrically connected to the first printed circuit board (420). Accordingly, the guide member (710) may be used as a conductive path for transmitting an electrical signal generated in the first printed circuit board (420) to the second printed circuit board (430), or for transmitting an electrical signal generated in the second printed circuit board (430) to the first printed circuit board (420).

In one embodiment, the guide member (710) may include an insertion hole (714) connected to the second opening (501) of the interposer (440). In one embodiment, the insertion hole (714) may be formed in the first support portion (711) of the guide member (710) located on the third surface (4403) of the interposer (440). In one embodiment, the insertion hole (714) may guide the nozzle (N) so that the nozzle (N) may be inserted into the second opening (501) of the interposer (440). The nozzle (N) may sequentially discharge the heat dissipation member between the first printed circuit board (420) and the second printed circuit board (430) through the insertion hole (714) of the guide member (710) and the second opening (501) of the interposer (440).

In one embodiment, the insertion hole (714) may be formed to have a smaller size than the second opening (501). In one embodiment, the size of the insertion hole (714) may be formed to such a size that the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) does not flow out of the interposer (440). Accordingly, the heat dissipation material filled between the first printed circuit board (420) and the second printed circuit board (430) may be prevented or reduced from being discharged out of the interposer (440) through the insertion hole (714). In one embodiment not shown in the drawing, the second opening (501) may be a hole formed in the third surface (4403) of the interposer (440). In one embodiment, the second opening (501) of the interposer (440) and the insertion hole (714) of the guide member (710) may be formed to have substantially the same size. Alternatively, in one embodiment, the insertion hole (714) of the guide member (710) may be formed to have a smaller size than the second opening (501) of the interposer (440). Accordingly, the heat dissipation member filled between the first printed circuit board (420) and the second printed circuit board (430) may be prevented from being released to the outside of the interposer (440) through the insertion hole (714).

According to one embodiment, as illustrated in FIGS. 11A and 11B, the guide member (710) may be provided with a flexible member (540) that covers the insertion hole (714). In one embodiment, the flexible member (540) may be disposed on the body of the guide member (710). In one embodiment, the flexible member (540) may be disposed on the front surface (e.g., the surface facing the -X direction with respect to FIG. 11A) of the guide member (710). In one embodiment not illustrated in the drawings, the flexible member (540) may be disposed on the back surface (e.g., the surface facing the +X direction with respect to FIG. 11A) of the guide member (710). In one embodiment, the flexible member (540) may have a plurality of cut portions that can be bent in the insertion direction of the nozzle (N) (e.g., +X direction with reference to FIG. 11A) when a nozzle (N) emitting a heat dissipation member is inserted into the insertion hole (714) to allow the nozzle (N) to be inserted into the first opening (4404) of the interposer (440), and block the insertion hole (714) while the nozzle (N) is not inserted.

FIGS. 12A and 12B are drawings explaining an embodiment in which a plurality of printed circuit boards and a plurality of interposers are stacked.

In the following, embodiments other than those described in FIGS. 7a to 11b are described, and redundant descriptions of components that are identical or similar to those described above are omitted.

According to one embodiment, an electronic device (400) (e.g., the electronic device (101) of FIG. 1 , the electronic device (200) of FIG. 2A , and/or the electronic device (300) of FIG. 3 ) may include a structure in which a plurality of printed circuit boards (e.g., a first printed circuit board (810), a second printed circuit board (820), and a third printed circuit board (830)) and a plurality of interposers (e.g., a first interposer (840) and a second interposer (850)) are stacked. In one embodiment, referring to FIGS. 12A and 12B , a first printed circuit board (810) (e.g., the first printed circuit board (420) and/or the second printed circuit board (430) of FIG. 8A ) - a first interposer (840) (e.g., the interposer (440) of FIG. 8A ) - a second printed circuit board (820) (e.g., the first printed circuit board (420) and/or the second printed circuit board (430) of FIG. 8A ) - a second interposer (850) (e.g., the interposer (440) of FIG. 8A ) - a third printed circuit board (830) (e.g., the first printed circuit board (420) and/or the second printed circuit board (430) of FIG. 8A )) may be stacked in this order. In one embodiment, the first interposer (840) may be formed in a loop shape including a first-first opening (841) (e.g., the first opening (4404) of FIG. 5a). In one embodiment, the first interposer (840) may include a first-second opening (842) formed on one side and connected to the first-first opening (841).
