METHOD FOR MAKING A DEBOSSED CONDUCTIVE FILM COMPOSITE.

摘要

A mechanically debossed foil (21) with a circuit pattern is laminated to a thin isotropic uncured and ungelled thermosetting resin film (11). The process comprises debossing a metal foil using a shaping tool with a surface possessing an embossed circuitry pattern, as described in the prior art. The foil (21) is separated from the tool. The separated metal foil (21) is placed in contact with the resin film (11) and forced into the film without significantly altering the foil shape. An optional support layer (18) may be bonded to the film.
