Abstract: Processing of materials and their combination to produce a thin foil-laminated adhesive dielectric thermosetting resin film and the conversion of it by a mechanical debossing procedure to impart a debossed and/or embossed printed circuit pattern directly thereon. A process for compositing a shaped metal foil containing a debossed electrical circuitry pattern and an thin isotropic uncured and ungelled thermosetting resin film and forming an adhesively joined composite conforming essentially to the shape of the predebossed metal foil. The process comprises placing a shaping tool with a surface possessing an embossed electrical circuitry pattern, as described in the prior art, and forcing the shaped surface and a surface of the metal foil into intimate contact to deform the metal foil to assume essentially the shape of the tool surface. The shaped metal foil is separated from contact with the tool surface.
