SURFACE-TREATED COPPER FOIL, COPPER FOIL WITH CARRIER, SUBSTRATE, RESIN SUBSTRATE, PRINTED WIRING BOARD, COPPER CLAD LAMINATE AND METHOD FOR PRODUCING PRINTED WIRING BOARD

摘要

The present invention provides a surface-treated copper foil capable of imparting the profile shape of the substrate surface after removal of the copper foil, the profile shape maintaining fine wiring formability and achieving satisfactory adhesion of electroless copper plating coating. The present invention also provides a resin substrate provided with a profile shape of the surface maintaining fine wiring formability and achieving satisfactory adhesion of electroless copper plating coating. The surface-treated copper foil of the present invention is a surface-treated copper foil having a surface-treated layer formed on a copper foil, and the surface roughness Sz of the surface of the surface-treated layer is 2 to 6 μm.
