Abstract:
1. A method for manufacturing a tape wiring board, the method comprising: providing a base film, the base film having a thermosetting polyimide tape and at least one thermoplastic polymer layer formed on at least one side of the thermosetting polyimide tape; impressing the at least one thermoplastic polymer layer by a mold having an impression pattern formed at the bottom surface to form a wiring pattern area, the impression pattern corresponding to a wiring pattern; and forming a conductive polymer layer on the wiring pattern area to form the wiring pattern, wherein providing a base film includes spraying and curing at least one of silane and silicone polymer solution on the thermoplastic polymer layer to form a first protection layer, wherein the wiring pattern area includes a convex portion of the thermoplastic polymer layer, and wherein forming a wiring pattern area includes removing the first protection layer formed on the thermoplastic polymer layer.
