いる。2. Description of the Related Art Conventionally, as an insulating protective film for electronic parts and the like, heat resistance and electrical and electrical properties have been improved.
Polyimide resin with excellent mechanical properties is used, but when forming the protective film, the polyimide resin is generally used in a solution of the precursor polyamic acid because it is unnecessary for the organic solvent, it was applied to the substrate Thereafter, a method of forming a desired polyimide resin film by heating and curing is adopted.
