发明名称 Carrier-attached copper foil and printed board using the copper foil
摘要 The present invention relates to a carrier-added copper foil and a print substrate using such copper foil characterized in comprising a resin layer and a functional material layer at least on a part of the copper foil. A carrier-added copper foil and a print substrate using such copper foil are obtained by forming an insulating layer and functional material layer having an area smaller than the area of the copper foil on the surface of the carrier-added copper foil with the screen printing method, thereby improving the handling of such copper foil, preventing the adhesion of contaminants such as resin powder on the copper foil surface during the cutting procedure, preventing scratches and dimples caused by foreign matter, and effectively preventing the generation of scratches, wrinkles and creases during the cutting, packaging and transportation procedures.
