Abstract

A printed circuit board is provided to prevent the disconnection of a signal transmission line by covering a contact part between a contact unit and a signal transmission line with a cover layer. A printed circuit board includes a signal transmission line(262) and a contact unit(267). The contact unit is formed in the end of the signal transmission line. The width of the contact unit is larger than the width of the signal transmission line. The cover layer is formed in one side of the printed circuit board to cover the signal transmission line. A hole(370) is formed in the cover layer to expose the remaining area of the contact unit except for the partial area of the contact unit adjacent to the signal transmission line to the outside. A branch(265) is connected to the center of the signal transmission line. The branch is protruded from the center of the signal transmission line to the direction different from the extension direction of the signal transmission line.

본 발명과 본 발명의 동작상의 이점 및 본 발명의 실시에 의하여 달성되는 목적을 충분히 이해하기 위해서는 본 발명의 바람직한 실시예를 예시하는 첨부 도면 및 도면에 기재된 내용을 참조하여야 한다.DETAILED DESCRIPTION In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the drawings.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 설명함으로써, 본 발명을 상세히 설명한다. 각 도면에 제시된 동일한 참조부호는 동일한 부재를 나타낸다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

본 명세서에 개시된 인쇄회로기판(printed circuit board: PCB)은 일반적인 인쇄회로기판일 수도 있고, 연성 인쇄회로기판일 수도 있다.The printed circuit board (PCB) disclosed herein may be a general printed circuit board or a flexible printed circuit board.

도 1은 인쇄회로기판의 예를 나타내는 도면이다.1 is a diagram illustrating an example of a printed circuit board.

도 1에 도시된 인쇄회로기판(160)은, 제1그라운드 레이어(164), 제1유전체 레이어(166), 및 신호전송라인(162)을 구비한다. 제1그라운드 레이어(164), 제1유전체 레이어(166), 신호전송라인(162)은 순차적으로 적층되고, 동일한 방향으로 신장된다.The printed circuit board 160 illustrated in FIG. 1 includes a first ground layer 164, a first dielectric layer 166, and a signal transmission line 162. The first ground layer 164, the first dielectric layer 166, and the signal transmission line 162 are sequentially stacked and extended in the same direction.

제1그라운드 레이어(164)는 금속성 물질(예를 들어, 구리)로 이루어지고, 접지에 연결된다. 제1유전체 레이어(166)는 유전 물질(예를 들어, 폴리-이미드)로 이루어진다. 신호전송라인(162)은 금속성 물질(예를 들어, 구리)로 이루어진다.The first ground layer 164 is made of a metallic material (eg, copper) and is connected to ground. First dielectric layer 166 is made of a dielectric material (eg, poly-imide). The signal transmission line 162 is made of a metallic material (for example, copper).

도 2는 본 발명의 실시예에 따른 인쇄회로기판을 나타내는 도면이다.2 is a view showing a printed circuit board according to an embodiment of the present invention.

도 2를 참조하면, 본 발명의 실시예에 따른 인쇄회로기판(200)은, 신호전송라인(262) 및 접촉부(267)를 구비한다. 접촉부(267)는 신호전송라인(262)의 끝단에 연결되고 신호전송라인(262)과 일체로 형성된다. 접촉부(267)의 폭은 신호전송라인(262)의 폭보다 넓다.2, the printed circuit board 200 according to the embodiment of the present invention includes a signal transmission line 262 and a contact portion 267. The contact portion 267 is connected to the end of the signal transmission line 262 and is integrally formed with the signal transmission line 262. The width of the contact portion 267 is wider than the width of the signal transmission line 262.

도 3은 본 발명의 실시예에 따른 커버 레이어를 나타내는 도면이다.3 is a view showing a cover layer according to an embodiment of the present invention.

도 4는 도 2의 인쇄회로기판과 도 3의 커버 레이어를 결합한 본 발명의 실시 예에 따른 인쇄회로기판을 나타내는 도면이다.4 is a diagram illustrating a printed circuit board according to an exemplary embodiment in which the printed circuit board of FIG. 2 and the cover layer of FIG. 3 are combined.

도 3과 도 4를 참조하면, 본 발명의 실시예에 따른 커버 레이어(300)는 인쇄회로기판(200)의 신호전송라인(262)이 형성된 면 전체를 덮는다. 다만, 커버 레이어(300)는 홀(370)을 구비한다. 홀(370)은, 접촉부(267)의 영역 중에서, 신호전송라인(262)에 가까운 일부 영역을 제외한 나머지 영역을 외부로 노출시킨다. 즉, 커버 레이어(300)는, 신호전송라인(262)과 접촉부(267)가 접하는 부분을 외부로 노출시키지 않는다. 이처럼, 굵기가 급격히 변하는 부분을 외부로 노출시키지 않음으로써, 인쇄회로기판(200)이 꺽이는 경우에 신호전송라인(262)이 끊어지는 것을 방지한다.3 and 4, the cover layer 300 according to the exemplary embodiment of the present invention covers the entire surface on which the signal transmission line 262 of the printed circuit board 200 is formed. However, the cover layer 300 includes a hole 370. The hole 370 exposes the remaining areas of the contact portion 267 except for some areas close to the signal transmission line 262 to the outside. That is, the cover layer 300 does not expose the contact portion of the signal transmission line 262 and the contact portion 267 to the outside. As such, by not exposing the portion whose thickness changes rapidly, the signal transmission line 262 is prevented from being broken when the printed circuit board 200 is bent.

도 5는 본 발명의 실시예와 비교할 목적으로 제공되는 비교예를 나타내는 도면이다.5 is a view showing a comparative example provided for comparison with an embodiment of the present invention.

도 5에 도시된 것처럼, 신호전송라인(262)과 접촉부(267)가 접하는 부분, 즉, 굵기가 급격히 변하는 부분이 홀(370)에 의하여 외부로 노출된다고 가정하면, 인쇄회로기판(200)이 꺽이는 경우에 신호전송라인(262)이 끊어지기 쉽다.As shown in FIG. 5, assuming that a portion where the signal transmission line 262 and the contact portion 267 contact each other, that is, a portion whose thickness changes rapidly, is exposed to the outside by the hole 370, the printed circuit board 200 is exposed. In the case of bending, the signal transmission line 262 is likely to be broken.

다시 도 2를 참조하면, 본 발명의 실시예에 따른 인쇄회로기판(200)은, 브랜치(265)를 더 구비할 수 있다. 브랜치(265)는 신호전송라인(262)의 중앙에 연결되고, 신호전송라인(262)의 중앙으로부터, 신호전송라인(262)이 신장되는 방향과 다른 방향으로 돌출된다. 브랜치(265)는 신호전송라인(262)의 적어도 한쪽에서 돌출될 수 있다. 예를 들어, 도 2에는 브랜치(265)가 신호전송라인(262)의 한쪽에서 신호전송라인(262)이 신장되는 방향과 수직으로 돌출되는 모습이 도시된다. 이처럼, 신호전송라인(262)의 중앙에 연결되는 브랜치(265)는 공진이 발생하지 않도록 한다.Referring back to FIG. 2, the printed circuit board 200 according to the embodiment of the present invention may further include a branch 265. The branch 265 is connected to the center of the signal transmission line 262, and protrudes from the center of the signal transmission line 262 in a direction different from the direction in which the signal transmission line 262 extends. The branch 265 may protrude from at least one side of the signal transmission line 262. For example, FIG. 2 shows the branch 265 protruding perpendicularly to the direction in which the signal transmission line 262 extends from one side of the signal transmission line 262. As such, the branch 265 connected to the center of the signal transmission line 262 prevents resonance from occurring.

도 6은 본 발명의 다른 실시예에 따른 인쇄회로기판을 나타내는 도면이다.6 is a view showing a printed circuit board according to another embodiment of the present invention.

도 6을 참조하면, 본 발명의 다른 실시예에 따른 인쇄회로기판(600)에서는, 브랜치(665)가 신호전송라인(562)의 양쪽에서 신호전송라인(262)이 신장되는 방향과 수직으로 돌출된다.Referring to FIG. 6, in the printed circuit board 600 according to another exemplary embodiment of the present invention, the branch 665 protrudes perpendicularly to the direction in which the signal transmission line 262 extends on both sides of the signal transmission line 562. do.
