摘要

PROBLEM TO BE SOLVED: To solve the problem that migration is likely to occur when silver-coated copper powder, whose surface is coated with silver, is used as a filler for an electrical conductive paste.;SOLUTION: The silver-coated copper powder composed of copper particles, whose surfaces are coated with silver, is heat-treated in a non-oxidizing atmosphere at 150-600°C and accordingly, the silver-diffused copper powder is obtained.;COPYRIGHT: (C)2008,JPO&INPIT
