  • Patent number: 4313995
    Abstract: There is disclosed a method for producing an electrical circuit board comprising the steps of selectively treating a portion of a conductive metal sheet in a pattern substantially corresponding to a predetermined printed circuit configuration and in a manner which renders the pattern portion of the sheet essentially adherent to a resin, placing the treated pattern portion of the sheet in direct contact with a layer of resin on the surface of an insulating substrate to form an assembly, uniformly heating the assembly to an elevated temperature to selectively bond the substrate to the treated pattern portion of the sheet, cutting the sheet along the perimeter of the pattern portions and stripping the non-pattern portions of the sheet from the substrate to form a circuit board.
    Type: Grant
