提供せんとするものである。[Detailed explanation of the invention] (a) Industrial application field This invention arranges a plurality of circuit blocks on a single printed circuit board, and after soldering the circuit components, V is carved on the printed circuit board. It is an object of the present invention to provide a printed circuit board suitable for use when dividing a printed circuit board along a character-shaped groove.

ら他端縁Ｑまで刻設している。(B) Prior art Conventionally, after mounting parts on a printed circuit board, perforations were created to divide the board into multiple blocks, and in order to avoid unevenness of the perforations at the edges of the division. There are V-shaped grooves in the holes. FIG. 1 is a drawing showing the prior art, and when carving a V-shaped groove 2 on a printed circuit board 1, the groove must be carved from one edge P of the printed circuit board to the other edge Q. There is. The reason for this is that the stop control of the V-cut cutting blade (not shown) cannot be precisely controlled.
When the cutting blade for V-cut is stopped midway, the carved V will be removed.
This is because the dimensions of the shape grooves vary. Therefore, when making a V cut, the cut is made from one end edge P of the printed circuit board 1 to the other end edge Q.

板の途中で止められないため、これらの問題に対
応できない面があつた。 On the other hand, in recent years, products that use printed circuit boards have become more multifunctional and fashionable, resulting in an increase in the number of printed circuit boards with complex external shapes.
Automation has caused problems with strength and warpage of printed circuit boards. V-cuts can be considered as a solution to these problems, but as mentioned earlier, they cannot be stopped in the middle of the printed circuit board, so they cannot deal with these problems.
(ハ) 目的
本考案はプリント基板の中央部までＶ字形溝を
入れることのできるプリント基板を提供するもの
である。(c) Purpose The present invention provides a printed circuit board in which a V-shaped groove can be formed up to the center of the printed circuit board.

法に選定する。(d) Structure and operation Figure 2 shows the printed circuit board of the present invention. That is,
A rectangular through hole 3 and an L-shaped through hole 3' are provided at predetermined positions on the printed circuit board 1. The lengths l 1 , l 2 , l 3 of these through holes 3, 3' are selected to be such that they can sufficiently absorb errors in the stopping position of the V-cut cutting blade.

される。 Note that 4 and 4' are perforated through holes, and one substrate 1 has these rectangular through holes 3, V with high dividing precision.
It is divided into three parts A, B, and C along the character-shaped groove 2 and the perforated hole 4 with low division accuracy, and also along the L-shaped hole 3', the V-shaped groove 2', and the perforated hole 4'. be done.
尚また、Ｖカツト用切削刃の停止位置の誤差を

言うまでもない。 It goes without saying that the through hole for absorbing the error in the stopping position of the V-cut cutting blade may have a cross shape or other various shapes as required.

ることができる。(e) Effect In this way, the present invention provides a rectangular through hole to absorb the stopping error of the V-cut cutting blade at a position away from the edge of the printed circuit board, so that the wiring conductive foil is close to the printed circuit board. Even when a division accuracy of
V-shaped grooves with high dividing accuracy can be carved at arbitrary positions on the printed circuit board, and problems with the strength of the printed circuit board and warping when the printed circuit board is taken together can also be solved.
また、配線導箔が近接して配設されていないた
め、プリント基板の分割の際、それ程精度を要さ
ない部分には分割精度の低いミシン目透孔を設け
てプリント基板の強度を保つようにしている。 In addition, since the wiring conductive foils are not placed close to each other, when dividing the printed circuit board, perforations with low dividing precision are provided in parts that do not require high precision to maintain the strength of the printed circuit board. I have to.
