Publication number: 20030222379Abstract: The present invention relates to a method of manufacturing a metal clad laminate for printed circuit board, characterized by direct adhesion of a conductive metal foil without use of a thermosetting resin having low melting points, an adherent film or an adhesive. The method includes forming fine protrusions on at least one surface of a fluorine-based resin insulation layer, roughening one surface of a conductive metal foil, laminating the fluorine-based resin insulation layer having fine protrusions on the roughened metal foil so that the roughened surface of the metal foil and the protrusion-formed surface of the insulation layer face each other to form a laminated body, and compressing the laminated body under vacuum, pressure and heat.Type: ApplicationFiled: February 21, 2003Publication date: December 4, 2003Inventors: Eun Song Baik, Jong Seok Song, Rae Ook Cho, Yu Cheol Yang
