제 1a 도는 본 고안을 절단하지 않는 상태를 도시한 정면도, (b)는 본 고안을 절단한 상태도를 도시한 정면도.Figure 1a is a front view showing a state not cutting the subject innovation, (b) is a front view showing a state diagram cut the subject innovation.
제 2 도는 종래의 미싱선과 미싱홀의 구조.2 is a structure of a conventional sewing machine and a sewing hole.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 미싱선 2 : 미싱홀1: Sewing machine 2: Missing hole
3 : 미싱선의 틈 4 : 미싱선의 길이3: gap of sewing machine line 4: length of sewing machine line
5 : 미싱홀이 차지하는 길이5: Length occupied by the missing hole
본 고안은 인쇄회로기판에 관한 것으로 특히 미싱선과 미싱홀을 다른 동박에 영향을 미치지 않고 인쇄회로기판이 전자제품장치내의 인쇄회로기판 레이 위에서 충분한 하중을 유지할 수 있게 한 절취가 용이한 인쇄회로기판에 관한 것이다.The present invention relates to a printed circuit board. In particular, the printed circuit board is provided in an easy-to-cut printed circuit board which enables the printed circuit board to maintain a sufficient load on the printed circuit board lay in the electronic device without affecting the sewing wire and the missing hole on other copper foils. It is about.
종래의 인쇄회로기판은 특정부분을 납댑 작업을 한 후 기구적인 문제로서 인쇄회로기판을 잘라내어야 할 필요가 있을 때 필요한 부분을 직선적인 형태로 미싱선과 미싱홀을 만들어 끊어내었다.The conventional printed circuit board cuts the necessary parts in a straight line when the need to cut the printed circuit board as a mechanical problem after the operation of the specific portion of the soldering operation.
그러나 필요 없는 부분의 인쇄회로기판을 끊고난 인쇄회로기판의 가장자리가 일정하지 않고 굴곡이 심하였을 뿐 아니라 인쇄회로기판을 끊어낸 부분은 굴곡이 심할 때는 1㎜이상의 굴곡이 나게 나타나게 되었다.However, the edges of the printed circuit boards, which cut off the printed circuit boards that were not needed, were not only irregular and severely curved. Also, the portions that cut off the printed circuit boards appeared to be more than 1 mm when the printed circuit boards were severely curved.
따라서 인쇄회로기판의 가장자리에 굴곡이 작을 경우에는 인쇄회로기판의 고정레일에 삽입될 경우 1㎜이상의 공차를 갖고 레일에 얹혀져서 삽입되고 인쇄회로기판의 가장자리에 굴곡이 크게 생길 경우에는 레일속으로 인쇄회로기판이 잘 삽입이 되지 않아서 라인 작업 과정에서 니퍼등의 공구로 잘라내야 하는등의 불편함이 있었을 뿐 아니라 인쇄회로기판에 부품이 조립된 상태로 인쇄회로기판의 레인에 얹혀지게 되거나 삽입되어지면 미싱홀이 끊어진 부분이 큰 공차로 인해 장치되어진 제품이 충격을 받게 되면 인쇄회로기판이 레인레서 빠지거나 레인의 틈을 통하여서 인쇄회로기판이 흔들려 부서질 위험이 있었고 또한 미싱홀의 끊어진 부분이 굴곡이 큰 경우 인쇄회로기판의 레일에 삽입이 잘 되지 않거나 너무 헐겁게 되어 제품의 신뢰성 및 생산성 저하의 문제가 발생하였다.Therefore, when the curvature of the printed circuit board is small, when it is inserted into the fixed rail of the printed circuit board, it is inserted and mounted on the rail with a tolerance of 1 mm or more, and when the curvature is large on the edge of the printed circuit board, it is printed into the rail. When the circuit board was not inserted well, it was inconvenient to cut it with a tool such as nipper during the line work process. In addition, when the component is assembled on the printed circuit board, it is placed on the lane of the printed circuit board or inserted. If the product that is installed due to the large gap of the missing hole is impacted, the printed circuit board may fall out of the lane, or the printed circuit board may be shaken through the gap in the lane. In this case, it is difficult to insert or become too loose on the rail of the printed circuit board. The problem of acid degradation occurred.
따라서 본 고안은 종래의 이와같은 제결함을 해소하기 위해 안출한 것으로 제 1 도는 제 2 도의 기존방식을 보안한 것으로 제 1 도의 인쇄회로기판(7)의 기준선(C)을 기준으로 필요 없는 부분(가)와 필요 있는 부분(나)으로 절단 할 때 미싱선(1)에 미싱선의 틈(3) 만큼 내려서 미싱홀(2)을 천공한다.Therefore, the present invention has been devised to solve such defects in the related art, and FIG. 1 is a security of the conventional method of FIG. 2, which is not necessary based on the reference line C of the printed circuit board 7 of FIG. A) and the necessary part (b) is cut into the sewing line 1 by the gap 3 of the sewing line, and the drilling hole 2 is drilled.
미싱선의 길이(4)는 미싱홀(2)이 차지하는 길이(5)보다 일반적으로 길게 형성하고 미싱선의 길이(4)의 형성된 홈(6)(6')은 미싱홀(2)과 같은 위치로 약간 기울려서 천공한다.The length 4 of the missing line is generally longer than the length 5 occupied by the missing hole 2, and the grooves 6 and 6 ′ formed of the length 4 of the missing line are positioned at the same position as the missing hole 2. Slightly tilted to puncture.
이와같이 천공된 인쇄회로기판(7)은 제 1a 도의 필요 없는 부분(가)와 필요 없는 부분(나)으로 분리하면은 제 1b 도와 같이 인쇄회로기판(7)이 절단된다.When the perforated printed circuit board 7 is separated into the unnecessary parts (a) and unnecessary parts (b) of FIG. 1a, the printed circuit board 7 is cut as shown in FIG. 1b.
따라서 본 고안과 같이 인쇄회로기판을 절단하면은 기준선(C)을 상회하는 굴곡이 생기지 않으면 기준선(C)및으로 미싱선의 길이(4)로 중심되어 미싱홀(2)부분도 50%정도가 기준선(C)에 접근하고 나머지 50%도 최저 0.5㎜의 공차를 두고 접근함으로서 레일에 삽입시 흔들리거나 충격에 인쇄회로기판(7)이 깨어질 염려가 없고 니퍼(NIPPER)등의 공구로 다시 절단할 필요가 없어 생산성과 신뢰성을 기여할 수 있는 효과가 있다.Therefore, when the printed circuit board is cut as in the present invention, if the bending not exceeding the reference line (C) does not occur, the reference line (C) and the length of the sewing line (4) are centered. Approach (C) and the remaining 50% with a tolerance of at least 0.5 mm so that the printed circuit board (7) may not be broken when inserted into the rail or be impacted, and it can be cut again with a tool such as NIPPER. There is no need to contribute to productivity and reliability.
