METHOD FOR MANUFACTURING METAL FOIL-CLAD LAMINATE

摘要

A method for manufacturing a metal foil-clad laminate in which the occurrence of voids and unevenness is suppressed compared with conventional ones even when a prepreg obtained from a curable resin composition containing a relatively large amount of an inorganic filler is used. A laminate and a metal foil-clad laminate has excellent moldability, a low thermal expansion coefficient, and high glass transition temperature and is excellent in the peel strength of the metal foil. A method comprises disposing one or more prepregs between metal foils so that the one or more prepregs are in contact with metal surfaces, and heating and pressurizing the one or more prepregs and the metal foils in a vacuum atmosphere to laminate the prepregs and the metal foils to obtain a metal foil-clad laminate; and further subjecting the metal foil-clad laminate to heating and pressurization treatment in a vacuum atmosphere.

1. A method for manufacturing a metal foil-clad laminate, comprising:
(A) an adhesion step of disposing one or more prepregs between metal foils so that the one or more prepregs are in contact with metal surfaces, and heating and pressurizing the one or more prepregs and the metal foils in a vacuum atmosphere to laminate the one or more prepregs and the metal foils to obtain a metal foil-clad laminate; and (B) a lamination molding step of further subjecting the metal foil-clad laminate to heating and pressurization treatment in a vacuum atmosphere.
