METHOD OF COMBINING METAL WITH SURFACE OF MOLDED CYCLOOLEFIN RESIN AND METAL-COMBINED MOLDED CYCLOOLEFIN RESIN

摘要

A method of combining a metal with the surface of a cycloolefin resin molding, especially one for combining a metal with a cycloolefin resin molding which is extremely reduced in permittivity and dielectric loss and has a considerably low water absorption and which is optimal as a component of a device for processing high-frequency electrical signals in a GHz region. The method comprises roughening at least part of the surface of a molded article of a cycloolefin resin or composition thereof so as to result in a ten-point average surface roughness, Rz, of 5 µm or higher and then forming a metal film on the molding surface by a wet plating technique.
