SUBSTRATE FOR FLEXIBLE WIRING BOARD AND FLEXIBLE WIRING BOARD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a flexible wiring board formed of a copper layer having good buckling resistance, and also to provide a substrate for flexible wiring board. SOLUTION: A double-layer flexible wiring substrate forming the copper layer for wiring includes adequate amount of sulfur and zinc into a copper-plated layer for wiring of the copper layer to form an electric wiring pattern. The copper layer is a plated substrate formed with the plating method. The flexible wiring board is manufactured using such substrate for flexible wiring board. COPYRIGHT: (C)2007,JPO&INPIT
