摘要

PROBLEM TO BE SOLVED: To provide a surface treated copper foil capable of providing a profile shape of a substrate surface after removal of a copper foil, maintaining fine wiring formation properties and achieving good adhesion force of a non-electrolytic copper plating film.;SOLUTION: The surface treated copper foil is adhered to a resin substrate for a printed wiring board from the surface treated layer side, and when the surface treated copper foil is removed, the black area ratio of the surface of the resin substrate from which the copper foil has been removed is 10 to 50%, in addition, the average diameter of holes in the surface of the resin substrate from which the copper foil has been removed is 0.03 to 1.0 μm.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2017,JPO&INPIT
