SUBSTRATE WITH CONDUCTOR LAYER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a substrate having a conductor layer used for a printed circuit board which is excellent in a tracking-resistance characteristic without spoiling an electrical insulation, and its manufacturing method. SOLUTION: The substrate with conductor layer comprises the conductor layer and an insulation layer superposed on the conductor layer through the film made by hardening an adhesive. The adhesive is blended with bridged acrylonitrile butadiene rubber particles at the time of applying. COPYRIGHT: (C)2004,JPO
