Continuous production of metal clad laminates.

摘要

A process for producing metal clad laminates comprising the steps, all in continuous manner, of: (a) joining a plurality of substrate sheets impregnated with a liquid resin capable of curing without generating volatile by-products to form a wet laminate; (b) applying a metal foil onto at least one side of the wet laminate; (c) preheating the wet laminate immediately before or after step (b) before the liquid resin is immobilized; (d) compressing and heating the wet laminate by a double belt press in its pressing zone to cure the laminate into a rigid state; (e) subjecting the lamiate to curing after releasing it from compression to complete the curing reaction and to relax internal stress therein; and (f) cutting the cured laminate to a predetermined length. e
