REINFORCING SHIELD FILM AND SHIELD FLEXIBLE PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a shield FPC with which coloring, surface printing and adhesion of a reinforcing plate are easy, which is not discolored and swollen even if it is heated in a process after solder reflow and which is superior in electromagnetic wave shielding property and in flexibility and to provide a reinforcing shield film suitable for using for FPC. SOLUTION: In the reinforcing shield film, a shield layer 8 is disposed on one face 7 of a cover film and an adhesive layer 10 formed of heat resistant and solvent resistant adhesive and a reinforcing film 6 which can easily be peeled from the adhesive layer are sequentially disposed on the other face. The film is stuck onto a substrate film 5 such as FPC. Conductive adhesive 8a in the shield layer 8 is heated (h) and pressurized (p) so that it is brought into contact with a part 3c of a ground circuit 3b. Then, the reinforcing film is peeled off (f).
