ル−ポールの精度も厳しく要求される。Conventional configurations and their problems In recent years, with the development of microelectronics, high wiring density has been required for boards on which highly accurate components such as LB work are mounted. It is realized as a wiring board. Some multilayer wiring boards are made of resin or alumina, but in particular, tungsten paste is screen printed on an alumina green sheet made of alumina particles and an organic binder, which is laminated and then fired. Aluminum multilayer wiring boards manufactured using this method are attracting attention. In this multilayer wiring board, a through hole is formed in the alumina green sheet for the purpose of interconnecting the wiring in each layer, and the through hole is filled with tungsten paste. Therefore, a large number of through holes, so-called through holes, are formed in a sheet for a multilayer wiring board, and as the wiring becomes denser, the accuracy of the null-pole is strictly required.

A method has been used in which a head (3a) is formed and a corresponding part (2) is ground on the bottle holding member (2).Therefore, if the positions of the through holes to be punched are close to each other, Head (3) of pin (3)
a) tend to interfere with each other, and the approach distance of the punched through holes is limited by the diameter of the pin head (3a).

間匙が生じてきた。Therefore, it is currently impossible to form small, punched through holes with high density. In addition, 11. The tip of the pin (3) must be in the same plane as the bottom surface of the IJ collar (4) when no load is applied, but in this festival, the length of the pin (3) must be precisely determined in advance. It needs to be processed. For this purpose, the viscosity of the pin (3) needs to be high, and the complicated grinding process required to insert the pin (3) into the bottle holding member (2) by a T degree is required. There was a problem that the manufacturing process was complicated and expensive. In addition, the density of the bottle arrangement is structurally inadequate for disaster prevention, and a basic problem has arisen in that it cannot be used as a mold for processing wiring boards, which will become denser in the future.

The mold manufacturing process can be simplified. The front joint retainer is provided with a through hole (c) in the mold (5) whose diameter and position U match the through hole D of the stripper 04, so that the pin Q and the retainer fit into the through hole of the mold (l). ] enables precise punching of the sheet. (c) The ins are formed in the rubber member mounting recesses provided in the upper plate α and the stripper α fan, respectively, and are formed wider in the rubber member. In addition, the shape of the bottle, ie the shape and thickness of the punch, can be selected arbitrarily, making it possible to handle a variety of punches.

At the same time, the concave part is filled with a hardening filler, so there is no need to provide a head to prevent the bottles from being punched out, and the distance between the bottles can be made extremely close, allowing for high-density, close punching. can also be easily done. In addition, the notch and hardening filler prevent the bottle from being pulled out, making it extremely easy to process the bottle and bottle holding member together with the stone.Furthermore, since the bottle does not have a head, the tip of the pin can be removed after assembly. By grinding the surface and the lower surface of the stripper, there is no problem with the machining accuracy in the longitudinal direction of the pin itself, and the machining becomes extremely simple. Therefore, it is possible to provide a sheet punching mold that can perform sheet punching with high density, is easy to manufacture, and is inexpensive.
