PROTECTIVE FILM FOR FPC, RESIN CONDUCTOR FOIL LAMINATE WITH PROTECTIVE FILM FOR FPC, AND METHOD OF MANUFACTURING FLEXIBLE PRINTED WIRING BOARD USING IT

摘要

PROBLEM TO BE SOLVED: To provide a resin conductor foil laminate which prevents chemical pollution of the resin surface of the resin conductor foil laminate or contamination of the resin surface with a foreign matter or a flaw while ensuring excellent handleability, and to provide a method of manufacturing a flexible printed wiring board capable of simultaneous processing of both sides with high productivity.;SOLUTION: The protective film for FPC has an adhesive layer for sticking a resin layer on one or both sides of a polyethylene terephthalate substrate which has a heat shrinkage rate of 0.5% or less in both length direction and width direction in conditions of 150°C, 30 minutes. The protective film for FPC is stuck detachably to the polyimide resin layer surface of a conductor foil laminate on which a polyimide resin layer is laminated with the adhesive layer for sticking a resin layer interposed therebetween.;COPYRIGHT: (C)2012,JPO&INPIT
