The present application is related to and claims the benefit under 35 U.S.C. .sctn.119(a) of a Korean patent application filed on Nov. 18, 2015 in the Korean Intellectual Property Office and assigned Serial Number 10-2015-0161492, the entire disclosure of which is hereby incorporated by reference.
The present disclosure relates to a shield can structure.
Various electronic components may be mounted on an electronic device such as a smartphone. For example, electronic elements or circuit lines may be mounted on a printed circuit board (PCB), and at least some of them may be electrically connected to each other. Meanwhile, electromagnetic waves may be generated by the electronic components. The electromagnetic waves generated by the electronic components may be harmful to the human body, and may act as noise against a device that is vulnerable to the electromagnetic waves. Accordingly, when the electronic components are mounted on the printed circuit board, the electronic components may be covered by a shield can or the like that may shield electromagnetic waves.
If a shield frame of the shield can, which is coupled to a printed circuit board, is formed to be long, an area in which the shield frame and the printed circuit board contact each other is widened during a surface mounted device (SMD) process so that a portion of the shield frame may come out from the printed circuit board. Accordingly, in the existing shield can structure, an area in which the shield frame contacts the printed circuit board may be reduced by arranging one or more openings at a lower end of a side surface of the shield frame at a specific interval, thereby making it possible to prevent a portion of the shield frame from coming out.
However, electromagnetic waves may be introduced and discharged through an opening formed at a lower end of a side surface of the shield frame. Accordingly, the electromagnetic waves introduced and discharged through the opening may badly influence the human body and may cause malfunctions of the electronic components.
Further, in the existing shield can structure, a shield frame and a shield cover may match with each other on the upper and lower surfaces of the printed circuit board, respectively, so that shield cans may be provided on the upper and lower surfaces of the printed circuit board. For example, the shield frames may be coupled to the upper and lower surfaces of the printed circuit board, respectively, and the shield covers may be arranged on the shield frame to cover the electronic components arranged within the shield can. However, the structure may make it difficult to interrupt the electromagnetic waves generated on the side surfaces of the printed circuit board.
To address the above-discussed deficiencies, it is a primary object to provide a structure of a shield can in which a shield cover covers an opening formed in a shield frame and a portion of a side wall of a printed circuit board.
In accordance with an aspect of the present disclosure, an electronic device includes a housing comprising a first plate, a second plate separated from the first plate, and a side member that surrounds at least a portion of a space between the first plate and the second plate, a printed circuit board arranged inside the housing and comprises a first surface that faces a first direction, a second surface that faces a second direction that is opposite to the first direction, and at least one side surface that faces a direction that is different from the first direction and the second direction, a first electronic component mounted on the first surface, a second electronic component mounted on the second surface, a first shield frame formed on the first surface to surround at least a part of the first electronic component and has a first opening in at least an area thereof, a second shield frame formed on the second surface to surround at least a part of the second electronic component and has a second opening in at least an area thereof, and a first shield cover comprising a first cover part and a first side part. The first cover part is supported by the first shield frame and is formed to cover an upper portion of the first electronic component. The first side part extends from the first cover part to a portion of the second shield frame and is formed to cover at least one side surface of the printed circuit board, the first opening, and at least a portion of the second opening.

For example, a processor, a memory, a communication module, and a camera module may be arranged on the printed circuit board 170. According to various embodiments, various electronic components may be arranged on the upper and lower surfaces (or the front and rear surfaces) of the printed circuit board 170. As illustrated in the drawings, a first electronic component 173 and a third electronic component 177 may be arranged on the upper surface (or the front surface or the first surface) of the printed circuit board 170, and a second electronic component 175 may be arranged on the lower surface (or the rear surface or the second surface) of the printed circuit board 170. According to an embodiment, the first electronic component 173 and the second electronic component 175 may be arranged on the upper and lower surfaces of the printed circuit board 170 at corresponding locations. In the following embodiments, the first to third electronic component 173, 175, and 177 will be described for convenience of description.
The electronic components arranged on the printed circuit board 170 may generate electromagnetic waves. Accordingly, at least one shield can (for example, the shield can 300 of FIG. 1) that may shield electromagnetic waves may be arranged on the printed circuit board 170 to cover at least one electronic component. The drawings illustrate that a first shield can 310 that covers the first electronic component 173 and the second electronic component 175 to provide a first shielding area 210 and a second shield can 330 that covers the third electronic component 177 to provide a second shielding area 230 may be arranged on the printed circuit board 170.
According to various embodiments, both of the first shield can 310 and the second shield can 330 have the same function of shielding electromagnetic waves, but the structures thereof may be different.

Further, the opposite edges of the printed circuit board 170 may be cut away by a specific size (for example, 0.2 mm) such that a space through which the shield cans may extend from one surface to an opposite surface of the printed circuit board 170.
According to various embodiments, the form, the size, and the locations of the shield cans may be different according to the form, the size, and the locations of the at least one electronic component, to which a shielding area is to be provided. For example, the form and the size of the shield cans also may be determined to correspond to the form and the size of the electronic component. Further, the locations of the shield cans may be determined to correspond to the location at which the electronic component is arranged. According to various embodiments, the printed circuit board 170 may be integrally provided as illustrated, and a plurality of separate printed circuit boards may be electrically connected to each other.
