It is known that the plate thickness accuracy and dimensional stability are superior to conventional laminated plates, but due to equipment constraints in this continuous molding, it is essential to harden the impregnated resin quickly. It is necessary to increase the curing speed by about 50 times compared to the case where the molding is performed by applying pressure between plates. In this case, if a fast-curing resin is used, if the thickness of the laminate is too large or the temperature of the laminate rises too slowly, the inside of the laminate cannot be made uniform and scratches may occur, resulting in poor appearance and poor heat resistance. There was a problem that the moisture resistance was poor and the reliability as a printed wiring board was low.

る。Metal foils include copper foil, aluminum foil, brass foil,
Ni・l Kel foil, stainless steel foil, iron foil, etc. can be used.
You can also form an adhesive layer on one side to improve adhesion.
. In this way, a laminate with a thickness of 3.2 fins or less, in which the required number of resin-impregnated substrates are stacked and metal foil is arranged on the upper and/or lower surfaces, is held between endless belts and a molding pressure of 2 to 30" is applied.
A metal foil-clad laminate is obtained by continuous heating and pressure forming using J/C1l. This is because if the thickness of the laminate exceeds 3.2 mm, the inside of the laminate cannot be made uniform during hot-press molding. In addition, the heating of the 1v1 layer is preferably 100 V or more, as this will rapidly reduce the resin melt viscosity of the resin-impregnated base material and at the same time cause rapid curing, so that residual stress due to resin flow will not remain in the laminate. It's a serious matter.
