摘要： PROBLEM TO BE SOLVED: To provide a polyimide film for COF high in dimensional accuracy and substantially free of large protrusions attributable to an internally added inorganic filler, smooth in surface and high in dimensional accuracy under moisture absorption, and giving high-quality copper-clad substrates, and to obtain a laminate reduced in causing spring-back and improved in the rigidity and dimensional accuracy under moisture absorption of the polyimide film compared to four-component polyimide film.
SOLUTION: The film comprises a polyimide that is produced by thermal imidation of a 3,3',4,4'-biphenyltetracarboxylic dianhydride and p-phenylenediamine as the respective main components. In the film, an inorganic filler prior to addition to film is less than 1 μm in avearge size and there are no protrusions attributable to inorganic fillers with larger average size. The film has a thickness of 25-35 μm. The laminate is obtained by subjecting the polyimide film for COF to discharge treatment under a vacuum followed by forming a substrate metallic thin film and then an electrically conductive metallic layer consisting of electrically conductive metallic deposit.
