## Background
CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY
The present application is related to and claims the priority under 35 U.S.C. § 119(a) to Korean Application Serial No. 10-2016-0003877, which was filed in the Korean Intellectual Property Office on Jan. 12, 2016, the entire content of which is hereby incorporated by reference.
TECHNICAL FIELD
Various embodiments of the present disclosure relate to an electronic device. For example, various embodiments of the present disclosure relate to an electronic device that includes a shield structure, and a method of manufacturing the electronic device.
BACKGROUND
Typically, an electronic device refers to a device that performs a specific function according to an equipped program (e.g., an electronic scheduler, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image/sound device, a desktop/laptop PC, or a vehicular navigation system), including a home appliance. For example, such an electronic device may output information stored therein as sound or an image. As the degree of integration of such an electronic device has increased, and as super-high speed and large capacity wireless communication has become popular, various functions have recently been equipped in a single mobile communication terminal. For example, various functions, such as an entertainment function (e.g., a game function), a multimedia function (e.g., a music/video reproducing function), a communication and security function for mobile banking, a schedule management function, and an e-wallet function, are integrated into a single electronic device, in addition to a communication function.
When the degree of integration of an electronic device increases, it may mean that electronic components mounted on a circuit board are miniaturized and the performances of the electronic components are improved. The electronic components may be manufactured in the form of an integrated circuit chip in which one circuit device (e.g., a processor, an audio module, a power management module, or a wireless frequency module) is incorporated, or in the form in which a plurality of circuit devices are integrated in a single integrated circuit chip.
SUMMARY
As the integration of degree of an electronic device increases, electromagnetic interference may occur between electronic components. For example, depending on the circuit device incorporated in an electronic component, electromagnetic waves may be generated when the electronic component is operated. The electromagnetic waves may degrade an operation performance of another electronic component.
In order to prevent the electromagnetic interference, various types of shield structures may be provided. For example, a conductive shield member may be provided to electrically isolate regions or spaces, which are provided with respective components, with respect to each other. However, it may become an impediment to the miniaturization in a printed circuit board because one or more holes or solder pads for mounting and fixing the conductive shield member should be disposed on at least one side of the printed circuit board, and it is necessary to secure a predetermined interval between one or more solder pads for mounting electronic components (e.g., an integrated circuit chip) on the surface of the printed circuit board and the solder pads for fixing the conductive shield member.
To address the above-discussed deficiencies, it is a primary object to provide a housing including a first face that faces a first direction; a printed circuit board including first and second board faces that are substantially parallel to the first face, and a side board face that faces a second direction that is different from the first direction, the printed circuit board being disposed within the housing; a first electronic component disposed in a first region of the first board face; a second electronic component disposed in a second region of the second board face that at least partially overlaps with the first region when viewed from above the first board face or the second board face; a first conductive shield member including a first side wall formed to face the second direction so as to extend at least a portion of the side board face, the first conductive shield member covering the first region; a second conductive shield member including a second side wall formed to face the second direction so as to extend at least a portion of the side board face, the second conductive shield member covering the second region; and at least one bonding material formed between the first side wall and at least a portion of the side board face and/or between the second side wall and at least a portion of the side board face. The second side wall and the first side wall may be engaged with each other in at least a portion of the side board face or adjacent to at least a portion of the side board face.
According to various embodiments of the present disclosure, a method of manufacturing an electronic device may include: an operation of providing a printed circuit board that includes a first board face, a second board face that is parallel to the first board face, and a side board face that interconnects the first and second board faces; an operation of forming a solder pad at least on the side board face; an operation of applying a first solder paste on a portion of the solder pad; performing a first reflow process to mount a first conductive shield member, which includes a first side wall extending to at least a portion of the side board face, on the printed circuit board to cover a first region using the first solder paste; an operation of applying a second solder paste on another portion of the solder pad; and performing a second reflow process to mount a second conductive shield member, which includes a second side wall extending to at least a portion of the side board face, on the printed circuit board to cover a second region by using the second solder paste.
Various embodiments of the present disclosure may provide an electronic device that includes a printed circuit board that is miniaturized while developing a stable operating environment of electronic components, and may also provide a method of manufacturing the electronic device.
Various embodiments of the present disclosure may provide an electronic device in which a shield structure (e.g., a conductive shield member) is stably fixed while a printed circuit board is miniaturized.

DETAILED DESCRIPTION
FIGS. 1 through 17, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged device.
Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.
In the present disclosure, the expression “have”, “may have”, “include” or “may include” refers to existence of a corresponding feature (e.g., numerical value, function, operation, or components such as elements), and does not exclude existence of additional features.
In the present disclosure, the expression “A or B,” “at least one of A or/and B,” or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B,” “at least one of A and B,” or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.
The expressions such as “first,” “second,” or the like used in various embodiments of the present disclosure may modify various elements regardless of order or importance, and do not limit corresponding elements. The above-described expressions may be used to distinguish an element from another element. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.
When it is mentioned that one element (e.g., a first element) is “(operatively or communicatively) coupled with/to or connected to” another element (e.g., a second element), it should be construed that the one element is directly connected to the another element or the one element is indirectly connected to the another element via yet another element (e.g., a third element). In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.
As used herein, the expression “configured to” may be interchangeably used with the expression “suitable for,” “having the capability to,” “designed to,” “adapted to,” “made to,” or “capable of.” The expression “configured to” may not necessarily mean “specially designed to” in terms of hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to.” For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g., embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.
The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. A singular expression may include a plural expression unless they are definitely different in a context. Unless defined otherwise, all terms used herein, including technical terms and scientific terms, may have the same meaning as commonly understood by a person of ordinary skill in the art to which the present disclosure pertains. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is the same or similar to their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

The side board face F3 may be disposed to face a second direction (e.g., the X-direction of FIG. 1) that is different from the first direction (Z) (e.g., to face a side face of the above-described electronic device).
According to various embodiments of the present disclosure, the electronic components 331 and 333 may be, for example, an integrated circuit chip(s) that is equipped with at least one of various circuit devices described above with reference to FIG. 2.

According to certain embodiments, the first conductive shield member 304a may be disposed to cover the first region so as to block an electromagnetic interference phenomenon between the first electronic components 331. According to various embodiments, when a plurality of first electronic components 331 are disposed to be adjacent to each other in the first region, the first conductive shield member 304a may include a partition formed therein so as to prevent the electromagnetic interference between the first electronic components 331 disposed in the first region.
Among the electronic components 331 and 333 according to various embodiments of the present disclosure, the second electronic components 333 may be mounted on the second board face F2. Some of the second electronic components 333 may be disposed to be adjacent to each other within a predetermined region (hereinafter, a “second region”) in the second board face F2. The second region may at least partially overlap with the first region when viewed from above the first board face F1 or the second board face F2. According to certain embodiments, the second conductive shield member 304b may be disposed to cover the second region so as to block an electromagnetic interference phenomenon between the second electronic components 333.

On the side board face F3, a portion of the first conductive shield member 304a and the second conductive shield member 304b may be alternately arranged along the longitudinal direction of the side board face F3. For example, a portion of the first conductive shield member 304a and a portion of the second conductive shield member 304b may be alternately engaged so as to form a line in a zigzag form.
FIG. 6 illustrates a perspective view of a shield structure of an electronic device according to various embodiments of the present disclosure.
FIG. 6 illustrates conductive shield members 604a and 604b mounted on a printed circuit board in a state of accommodating at least one electronic component in which it is noted that the printed circuit board or the like is omitted in order to clearly show the configurations of the conductive shield members 604a and 604b more clearly.
Referring to FIG. 6, the shield structure of the electronic device (e.g., the electronic device 100 of FIG. 1) according to various embodiments of the present disclosure may include a first conductive shield structure 604a (e.g., the first conductive shield member 304a of FIGS. 3 to 5) disposed to cover a first region on the first board face of the printed circuit board (e.g., the printed circuit board 303 of FIGS. 3 to 5) and a second conductive shield member 604b (e.g., the second conductive shield member 304b of FIGS. 3 to 5) disposed to cover a second region on the second board face of the printed circuit board. As described with reference to FIGS. 3 to 5, the second region may at least partially overlap with the first region when viewed from above the first board face F1 or the second board face F2. In certain embodiments, the first conductive shield member 604a and the second conductive shield member 604b may be mounted to partially face each other across the printed circuit board.
According to various embodiments of the present disclosure, the first conductive shield member 604a may include a first flat plate 641a facing the first board face of the printed circuit board (e.g., the above-mentioned first region) and side walls extending from the first flat plate 641a. The side walls may include a first side wall 643a extending to at least a portion of the side board face (e.g., the side board face F3 of FIG. 5) of the printed circuit board from the edge of the first flat plate 641a. For example, the first side wall 643a may be formed to face the same direction as the side board face F3 (e.g., the X-direction of FIG. 1). According to certain embodiments, when the first conductive shield member 604a is mounted on the first board face F1, the first flat plate 641a and the first side wall 643a may form a space that accommodates and isolates some of the above-described first electronic components (e.g., the first electronic component 331 of FIG. 3), together with the first region.
According to various embodiments of the present disclosure, the second conductive shield member 604b may include a second flat plate 641b facing the second board face of the printed circuit board (e.g., the above-mentioned second region) and side walls extending from the second flat plate 641b. The side walls may include a second side wall 643b extending to at least a portion of the side board face (e.g., the side board face F3 of FIG. 5) of the printed circuit board from the edge of the second flat plate 641b. For example, the second side wall 643b may be formed to face the same direction as the side board face F3 (e.g., the X-direction of FIG. 1). For example, when the second conductive shield member 604a is mounted on the second board face F2, the second flat plate 641b and the second side wall 643b may form a space that accommodates and isolates some of the above-described second electronic components (e.g., the second electronic component 333 of FIG. 3), together with the second region.
According to various embodiments, in the side board face F3 and/or in the vicinity of the side board face F3, the second side wall 643b and the first side wall 643a may be matingly engaged with each other to form a zigzag line 645. For example, the first side wall may include an edge having first repeated patterns, and the second side wall may include an edge having second repeated patterns that are engaged with the first repeated patterns. In certain embodiments, the zigzag line 645 may be positioned within the thickness range of the side board face F3. In certain embodiments, the zigzag line 645 may be partially positioned out of the thickness range of the side board face F3.
According to various embodiments of the present disclosure, when the first conductive shield member 604a and the second conductive shield member 604b are mounted on the printed circuit board, the first side wall 643a and the second side wall 643b may be disposed in a state where the faces thereof facing the side board face F3 are positioned in a substantially common plane. Here, from the “substantially common surface,” it means that the inner faces of the first side wall 643a and the second side wall 643b may be arranged to be parallel to each other and/or to be inclined to each other within a range of design allowance values in the state where the first side wall 643a and the second side wall 643b are mounted on the printed circuit board.
FIG. 7 illustrates a sectional view of a shield structure of an electronic device according to various embodiments of the present disclosure.
Referring to FIG. 7, the shield structure of the electronic device according to various embodiments (e.g., the electronic device 100 of FIG. 1) may include a first conductive shield member 704a mounted on the top surface of the printed circuit board 703, a second conductive shield member 704b mounted on the bottom surface of the printed circuit board 703, and a bonding material 705. The bonding material 705 may include, for example, a fillet formed in a reflow operation during a soldering or surface mounting process, and may fixedly mount the first conductive shield member 704a and the second conductive shield member 704b on the printed circuit board 703. The bonding material 705 may include inclined faces 751a and 751b that extend to the inner face of the first conductive shield member 704a and the inner face of the second conductive shield member 704b, respectively, on any one side of the printed circuit board 703. According to various embodiments, the bonding material 705 may be formed between at least a portion of first side wall of the first conductive shield member 704a (e.g., the first side wall 643a of FIG. 6) and at least a portion of a side board face of the printed circuit board 703 and/or between at least a portion of a side wall of the second conductive shield member 704b (e.g., the second side wall 643b of FIG. 6) and at least a portion of the side board face of the printed circuit board 703 (e.g., the side board face F3 of FIG. 5).
In certain embodiments, the bonding material 705 may be exposed to the outside of the first conductive shield member 704a or the outside of the second conductive shield member 704b. For example, the bonding material 705 may be partially exposed to the outside through a gap 745 between the side wall of the first conductive shield member 704a and the side wall of the second conductive shield member 704b (e.g., the portion indicated by reference numeral “745”). According to various embodiments, the above-described zigzag line (e.g., the zigzag line 645 of FIG. 6) may be sealed by the bonding material 705 so as to strengthen the shield performance by the first conductive shield member 704a and/or the second conductive shield member 704b. 
In certain embodiments, the above-described electronic device (e.g., the electronic device 100 of FIG. 1) may further include a solder pad that enhances bonding affinity between the printed circuit board 703 and the bonding material 705. The solder pad may provide a print region of a solder paste that forms the bonding material 705, or may limit a region in which the solder paste melt during a reflow operation may be spread on the printed circuit board 703. The configuration of the solder pad will be described in more detail with reference to, for example, FIG. 10.
FIG. 8 illustrates a view for describing various modifications of a shield structure of an electronic device according to various embodiments of the present disclosure.
Referring to FIG. 8, in a shield structure of an electronic device according to various embodiments of the present disclosure (e.g., the electronic device 100 of FIG. 1), a zigzag line 845, which is formed as a portion of a first conductive shield member 804a (e.g., the first side wall 641a of FIG. 6) and a portion of a second conductive shield member 804b (e.g., the second side wall 641b of FIG. 6) are matingly engaged with each other, may have various forms. For example, the zigzag line 845 may be formed to have various shapes (e.g., a shape based on a rectangular shape, a shape based on a triangular shape, and a shape based on a circular arc shape). In certain embodiments, the bonding material 705 may bond each of a portion of the first conductive shield member 804a (e.g., the first side wall 641a of FIG. 6) and a portion of the second conductive shield member 804b (e.g., the second side wall 641b of FIG. 6) to the side board face of the printed circuit board and may be formed to seal at least the zigzag line 845, thereby further strengthening the performance of the shield structure.
FIG. 9 illustrates a flowchart for describing a method of manufacturing an electronic device 900 according to various embodiments of the present disclosure. FIGS. 10, 11, 12, 13, 14, 15 and 16 illustrate views sequentially of an aspect in which a shield structure of an electronic device according to various embodiments of the present disclosure is formed.
Prior to discussing the method of manufacturing an electronic device 900 according to various embodiments of the present disclosure, it is noted that FIGS. 13 and 14 illustrate a printed circuit board in a state where the top side and bottom side thereof are reversed as compared to FIG. 11 or FIG. 12. FIGS. 15 and 16 illustrate a printed circuit board in a state where the top side and the bottom side thereof are reversed. In the following detailed description or illustration of drawings, it is noted that descriptions will be made assuming that a first conductive shield member 1004a is mounted on the top side or a first board face of the printed circuit board 1003, and a second conductive shield member 1004b is mounted on the bottom side or a second board face of the printed circuit board 1003.
It is noted that while the printed circuit board 1003 according to various embodiments of the present disclosure is mounted with various electronic components, the electronic components or the like are illustrated in a simplified form in FIGS. 10 to 16 for the purpose of conciseness of the drawings and descriptions to be made with reference to the drawings. A manufacturing method to be described below may be a portion or the whole of a surface mount process, and shield structures to be described below (e.g., the first conductive shield member 1004a and the second conductive shield member 1004b) may be mounted on the printed circuit board 1003 after at least some of the above-mentioned electronic components are mounted first.
Referring to FIG. 9, the manufacturing method 900 may include forming solder pads in operation 901, applying a first solder paste in operation 902, a first reflow operation 903, applying a second solder paste in operation 904, and/or a second reflow operation 905. According to various embodiments of the present disclosure, the manufacturing method 900 may further include an operation of providing the above-mentioned printed circuit board (e.g., the printed circuit board 103 of FIG. 1).
According to various embodiments of the present disclosure, forming the solder pads in operation 901 may include a portion of, for example, the operation of providing the above-mentioned printed circuit board (e.g., the printed circuit board 303 illustrated in FIGS. 3 to 5). For example, further referring to FIG. 10, various forms of printed circuit patterns may be formed on the printed circuit board 1003, and the solder pads 1031 may be formed in the process of forming such printed circuit patterns. For example, the solder pads 1031 may be a portion of a printed circuit pattern formed on the printed circuit board 1003. In certain embodiments, the solder pad 1031 may be formed at least on a side board face of the printed circuit board 1003 (e.g., the side board face F3 of FIG. 5). In certain embodiments, one end of each solder pad 1031 may be positioned on the first board face (e.g., the top side) of the printed circuit board 1003, and the other end may be positioned on the second board face (e.g., the bottom side) of the printed circuit board 1003.
According to various embodiments of the present disclosure, applying the first solder paste in operation 902 may include an operation of applying or printing the first solder paste on a portion of each solder pad 1031. Further referring to FIGS. 10 and 11, in certain embodiments, the first solder paste 1051 may be applied to one end of the solder pad 1031 on the first board face of the printed circuit board 1003. According to various embodiments, a first mask 1001a, which is formed with one or more first openings 1011, may be used in order to apply the first solder paste 1051. For example, the first mask 1001a is placed on the printed circuit board 1003, and then the solder paste is applied onto the first mask 1001a such that the first solder paste 1051 may be applied to regions corresponding to the first openings 1011. The first openings 1011 may be positioned to correspond to the solder pads 1031 on the first board face of the printed circuit board 1003, and may have a size (e.g., width) that is smaller than one end of each of the solder pads 1031. For example, the width of each first opening 1011 (e.g., the length of the first opening 1011 in the horizontal direction in FIG. 10) may be formed in a range of 0.15 mm to 0.5 mm, and may vary depending on the size of one end of the corresponding solder pad 1031.
According to various embodiments of the present disclosure, the first reflow operation 903 may heat the printed circuit board 1003 at a predetermined temperature in a state where the first conductive shield member 1004a is placed to cover the first region of the printed circuit board 1003. The first conductive shield member 1004a may include a first flat plate 1041a that faces the first region and a first side wall 1043a that extends from the first flat plate.
According to various embodiments of the present disclosure, in the first reflow operation 903, the first solder paste 1051 may be molten to be spread between the solder pads 1031 and the first conductive shield member 1004a (e.g., the inner face of the first side wall). Further referring to FIG. 12, when cooled in this state, the molten first solder paste 1051 may be cured to form a first bonding material 1053. The first bonding material 1053 may include a first inclined face 1053a that extends from the solder pad 1031 to the inner surface of the first side wall 1043a on the first board face of the printed circuit board 1003 (e.g., the top side of the printed circuit board). The first inclined face 1053a may be formed by a surface tension acting while the molten first solder paste 1051 is cured.
In certain embodiments, after the first bonding material 1053 is formed, a certain gap G may be formed between the side board face of the printed circuit board 1003 and the first side wall 1043a. For example, the gap G formed between the solder pads 1031 on the side board face and the first side walls 1043a may be about 0.05 mm. In the second reflow operation 905 to be described later, a part of the molten second solder paste may flow into the gap G to fuse with the first bonding material 1053 to form a bonding material (e.g., the bonding material 705 of FIG. 7).
According to various embodiments of the present disclosure, applying the second solder paste in operation 904 may include an operation of applying or printing the second solder paste on another portion of each solder pad 1031. Further referring to FIGS. 13 and 14, in certain embodiments, the second solder paste 1055 may be applied to the solder pads 1031 on the second board face (e.g., the bottom side) of the printed circuit board 1003 and/or on the side board face of the printed circuit board 1003. According to various embodiments, a second mask 1001b, which is formed with one or more second openings 1013, may be used in order to apply the second solder paste 1055. For example, the second mask 1001b is placed on the printed circuit board 1003, and then the solder paste is applied onto the second mask 1001b such that the second solder paste 1055 may be applied to regions corresponding to the second openings 1013. In certain embodiments, the width of each second opening 1013 (e.g., the length of the second opening 1013 in the horizontal direction in FIG. 13) may be formed in a range of 0.2 mm to 0.5 mm, and may vary depending on the size of another portion of the corresponding solder pad 1031 (e.g., a portion intended to apply the second solder paste).
According to various embodiments of the present disclosure, the second openings 1013 may be positioned to correspond to the solder pads 1031 on the second board face of the printed circuit board 1003, and may have a size (e.g., width) that is smaller than one end of each of the solder pads 1031. For example, one end of each second opening 1013 may be positioned outside the side board face of the printed circuit board 1003. It can be seen that the second solder paste 1055 applied using the second mask 1001b is formed on another portion of the solder pads 1031 on the second board face and the side board face of the printed circuit board 1003. In certain embodiments, even in the state in which the second solder paste 1055 is applied, the gap G, which is formed between the side board face of the printed circuit board 1003 and the first side wall 1043a, may be maintained as an empty space.
In the specific embodiment of the present disclosure, an operation of using a mask is exemplified in the operation of applying each of the first solder paste 1051 and the second solder paste 1055, but the present disclosure does not need to be limited thereto. For example, a method to be used in the operation of applying a solder paste may be different from that of the above-described embodiment as long as it is possible to form each of the first solder paste and the second solder paste having a desired size at a desired position and in a desired region.
According to various embodiments of the present disclosure, the second reflow operation 905 may heat the printed circuit board 1003 at a predetermined temperature in a state where the second conductive shield member 1004b is placed to cover the second region of the printed circuit board 1003. The second conductive shield member 1004b may include a second flat plate 1041b that faces the second region and a second side wall 1043b that extends from the second flat plate.
Further referring to FIG. 15, the applied second solder paste 1055 may have a viscosity of certain extent. For example, when the second conductive shield member 1004b is disposed to face the second region of the printed circuit board 1003, a part B of the second solder paste 1055 may flow out to the outside through the gap between the first conductive shield member 1004a and the second conductive shield member 1004b. The viscosity of the second solder paste 1055 may prevent the flowing-out part B from being separated, falling down, or flowing to the outer surface of the first conductive shield member 1004a or the second conductive shield member 1004b. According to various embodiments, the second conductive shield member 1004b may be disposed on the printed circuit board 1003 in a state where a part of the second conductive shield member 1004b is matingly engaged with a part of the first conductive shield member 1004a. 
According to various embodiments of the present disclosure, when heated at a predetermined temperature in the state where the second conductive shield member 1004b is disposed, the second solder paste 1055 may be molten to be spread between the solder pads 1031 and the second conductive shield member 1004b (e.g., the inner face of the second side wall 1043b). Further referring to FIG. 16, when cooled again in this state, the molten second solder paste 1055 may be cured to form a second bonding material 1057. The second bonding material 1057 may include a second inclined face 1057a that extends from the solder pad 1031 to the inner surface of the second side wall 1043b on the second board face of the printed circuit board 1003 (e.g., the bottom side of the printed circuit board). The second inclined face 1057a may be formed by a surface tension acting while the molten second solder paste 1055 is cured.
In certain embodiments, the molten second solder paste 1055 may flow into a space (e.g., the gap G of FIG. 14), which is formed between the side board face of the printed circuit board 1003 and the inner face of the first side wall 1043a, due to a capillary phenomenon. In the second reflow in operation 905, the first bonding material 1053 may also be heated to be partially molten, and may fuse with the second solder paste 1055 within the gap G. For example, in the second reflow operation 905, the second bonding material 1057 is formed in a state where it fuses with the first bonding material 1053, and the first bonding material 1053 and the second bonding material 1057 may be combined with each other so as to form one bonding material 1005.
According to various embodiments, a part of the bonding material 1005 may be exposed to the outside of the first conductive shield member 1004a or the second conductive shield member 1004b through the gap between the first side wall 1043a and the second side wall 1043b. For example, the first side wall 1043a and the second side wall 1043b may be disposed to be matingly engaged with each other on the side board face of the printed circuit board 1003 and/or in the vicinity of the side board face of the printed circuit board 1003, and a part of the bonding material 1005 may be exposed to the outside through the boundary between the first side wall 1043a and the second side wall 1043b (e.g., the zigzag line 645 of FIG. 6). In certain embodiments, the bonding material 1005 may seal the boundary between the first side wall 1043a and the second side wall 1043b, thereby improving the shield performance of the shield structure including the first conductive shield member 1004a and the second conductive shield member 1004b. 
In certain embodiments, the bonding material 1005 may form a fillet including each of the first inclined face 1053a and the second inclined face 1057a so as to fix a part of the first conductive shield member 1004a (e.g., the first side wall 1043a) to the first board face of the printed circuit board 1003 and a part of the second conductive shield member 1004b (e.g., the second side wall 1043b) to the second board face of the printed circuit board 1003. In addition, or alternatively, the bonding material 1005 may fix a part of the first conductive shield member 1004a (e.g., the first side wall 1043a) to the side board face of the printed circuit board 1003 and a part of the second conductive shield member 1004b (e.g., the second side wall 1043b) to the side board face of the printed circuit board 1003.
According to various embodiments, the first conductive shield member 1004a or the second conductive shield member 1004b may be both of the first or second board face and the side board face of the printed circuit board 1003 when being mounted on, and fixed to, the printed circuit board 1003. For example, the first conductive shield member 1004a or the second conductive shield member 1004b may be rigidly mounted on, and fixed to, the printed circuit board 1003.
FIG. 17 illustrates a view for describing an electronic device manufactured using the manufacturing method according to various embodiments of the present disclosure and/or the components of the electronic device.
According to various embodiments of the present disclosure, an electronic device (hereinafter, referred to as an “electronic device 1700”) and/or components of the electronic device may include a first conductive shield member 1704a mounted to face a first board face (e.g., the first board face F1 of FIG. 3) of printed circuit board 1703 (e.g., the printed circuit board 303 of FIGS. 3 to 5), and a second conductive shield member 1704b mounted to face a second board face (e.g., the second board face F2 of FIG. 3) of the printed circuit board 1703.

The printed circuit board 1703 may include at least one electronic component 1733 (e.g., an integrated circuit chip) mounted on the first board face and/or the second board face. In the present embodiment, an example is disclosed in which the electronic component 1733 is mounted on the first board face of the printed circuit board 1703, but the present disclosure does not need to be limited thereto.
