本発明は、印刷回路板を打抜プレスで打抜く時に起こる
打抜箔穴詰シによる不良をなくするた−めの印刷回路板
の製造方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to manufacturing printed circuit boards to eliminate defects caused by punching foil holes that occur when printed circuit boards are punched out using a punching press. It is about the method.

スで打抜かれて作られている。C. Prior Art] A printed circuit board is manufactured by etching a copper-clad laminate to form a circuit, printing a solder resist thereon, and then punching it out using a punching press.
従来、印刷回路板を打抜きプレスで打抜く際、円柱状で

シを起こす欠点を持っている。Conventionally, when punching printed circuit boards with a punching press, punching was performed using a circular punching pin with a cylindrical shape and a flat tip. When punching is performed using such a punching pin with a flat circular tip, the punching foil is attached to the tip of the punching pin, and when the punched printed circuit board is knocked out from the punching press,
The punched foil has the disadvantage of re-entering the punched hole, causing the punched foil hole to become clogged.
最近、ノぐターンの細線化にともない、ピン径が小さく
、なシ、ピン間が狭くなってきたため、基板と銅箔の剥
離が起きやすくなり、穴詰りによる不良が大きな問題と
なってきている。Recently, with the thinning of the wires in the nogturns, the pin diameter has become smaller and the distance between the pins has become narrower, making it easier for the copper foil to separate from the board, and defects due to hole clogging have become a major problem. .

々研究を進めて本発明を完成するに至ったものである。The inventors of the present invention have been conducting research in an attempt to create a method for manufacturing printed circuit boards that does not cause defects due to hole clogging caused by punching foil during punching, and as a result, by changing the shape of the tip of the punching pin. We have found that it is possible to reduce the adhesion of punched foil to punching pins, and based on this knowledge, we have conducted various studies and completed the present invention.

特徴とする印刷回路板の製造方法である。When manufacturing a printed circuit board using a single-sided or double-sided metal foil-covered laminate, the present invention provides a protrusion with a shape other than the original shape, such as a cross shape, a radial shape, an oval shape, or a polygon shape, at the tip of a punching pin. This is a method for manufacturing a printed circuit board, characterized in that the printed circuit board is punched out using formed punching pins.

。The metal foil of the metal foil-clad laminate used in the present invention is any metal foil mainly made of copper. In addition, resins for laminates include phenolic resin, melamine resin, urea resin, epixy resin,
These include thermosetting resins in general, such as diallyl phthalate resin, unsaturated polyester resin, polyimide resin, and polybutadiene resin. The base material for the laminate includes fiber paper, cotton cloth, cotton nonwoven fabric, synthetic fiber cloth, synthetic fiber nonwoven fabric, asbestos cloth, asbestos paper, glass cloth, glass fiber, nonwoven fabric, and the like.

形状の突起部を形成しであるものである。In the present invention, the shapes of the tips of the punching pins are cross-shaped (8), radial-shaped), elliptical (C),
It forms a protrusion in a shape other than the original shape, such as a triangular shape (2), a rectangular shape (2), or a star shape (2).
印刷回路板を製造するにあたって、打抜ピンで打抜かれ

のような形状の突起で銅箔に切シ込みを入れて、打抜剤
を破壊させて打抜く。In manufacturing printed circuit boards, the hole (see Figure 1) is formed at the tip of the punching pin just before it is punched out.
Cut a notch into the copper foil using a protrusion shaped like this to destroy the punching agent and punch it out.

抜ピンに付着しにくくなるためである。However, the shape of the punching agent remains circular, and the contact area with the punching pin becomes wider, making it easier to adhere to the punching pin.
With a punching pin shaped like the one above, the punching agent has a cut in the punching agent, so the punching agent is easily broken or torn and destroyed), and the contact area with the punching pin is small, so it is difficult to punch the punching agent. This is because it becomes difficult to adhere to the pin.

製造方法である。According to the method of the present invention, it is possible to reduce defects caused by punching foil holes during the punching process in printed circuit board manufacturing,
The productivity of good circuit boards can be greatly increased. Furthermore, it is an extremely efficient manufacturing method because there is no need to remove large pieces of foil from circuit boards with clogged holes, leading to a reduction in man-hours.
