A laminated plate composed of resin impregnated glass cloth and metal foil is obtained by multi-stage press and long-time heating and pressing for 1-2 hours, so molding distortion remains in the laminated plate and the laminated plate is printed. There is a drawback that warpage is generated by heat when processing an electronic component into a wiring board or mounting an electronic component on a printed wiring board, which hinders an automatic processing process. In particular, the tendency was large in a single-sided metal foil-clad laminate.

る点でよく望ましいことである。If necessary, a filler such as aluminum hydroxide, talc, silica, alumina or the like can be added to the resin. Further, the resin may be used as it is, but it is preferable to use it after degassing under reduced pressure in order to suppress the generation of bubbles in the resin-impregnated cloth. As the long copper foil, a single copper foil, an alloy thereof, or a composite foil is used. If necessary, an adhesive layer may be provided on one side of the foil to further improve the adhesiveness. Metal foils such as copper, aluminum, stainless steel, and brass can be used as the release metal foil. As the laminating roll, those made of metal, comb, synthetic resin, or those having a metal roll surface lined with rubber or synthetic resin are often optional. The curing temperature and curing time of the long strip-shaped laminate can be selected depending on the type of the resin, but it is important that the curing be performed at no pressure to 20 kg / cm 2 .
Regarding the after-curing after cutting, it is preferable to heat the resin to a temperature higher than the thermal deformation humidity of the used resin in order to remove residual strain.
