METAL-COATED POLYIMIDE FILM

摘要

Disclosed is a metal-coated polyimide film which is excellent in long-term adhesion reliability and various dimensional stabilities and thus suitable for wiring boards for high-density mounting such as COF. Specifically disclosed is a metal-coated polyimide film wherein a metal layer is directly formed on one or both surfaces of a non-thermoplastic polyimide film without using an adhesive. This metal-coated polyimide film is characterized in that the non-thermoplastic polyimide film contains a non-thermoplastic polyimide resin having a block component of a thermoplastic polyimide.
