LAMINATE MANUFACTUIRING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laminate manufacturing method capable executing stable production at a high yield by avoiding defects in appearance due to transfer of a step at the end of a laminate occurring in a process of manufacturing a metal clad laminated plate for circuit boards using a resin film as the insulation layer and defects in appearance occurring in heat treatment of the laminate and associated with fusion of a molten film with a metal foil of an adjacent layer.

SOLUTION: The method for manufacturing a laminate having metal foil on one or both sides of a resin film includes the step of heat-treatment of the wound laminate roll after the film and metal foil are laminated and wound around a winding core in the form of a roll, with at least the winding starting end of the laminate in the roll kept free from the contact pressure from the surface of the outer laminate portion and the winding core surface.
