ELECTROMAGNETIC WAVE-SHIELDING COVERLAY FILM, METHOD FOR MANUFACTURING FLEXIBLE PRINTED WIRING BOARD, AND FLEXIBLE PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave-shielding coverlay film comprising a coverlay film imparted with a function of blocking an electromagnetic noise, which is excellent in tackiness after hot-pressing, blocking prevention between insulating layer surfaces and punching processability.SOLUTION: The electromagnetic wave-shielding coverlay film comprises an insulating resin layer (A) containing a colorant (a), a conductive layer (B) containing a conductive filler (b), and an insulating adhesive layer (C), successively layered. A method for manufacturing a flexible printed wiring board is also provided.
