METHOD OF MANUFACTURING WIRING SUBSTRATE AND WIRING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To improve adhesion strength of a plating film even if a resin-metal composite layer is thin, 10 to 200 nm in concrete. SOLUTION: A resin-metal composite layer is subjected to plating, and then a resin substrate is heated to shrink a resin matrix. The precipitated plating metal is surrounded by the shrunk resin, so that the adhesion strength of a plating film can be further improved. COPYRIGHT: (C)2009,JPO&INPIT
