FLEXIBLE LAMINATE BOARD, PROCESS FOR MANUFACTURE OF THE BOARD, AND FLEXIBLE PRINT WIRING BOARD |
摘要 |
A process for production of a flexible laminated sheet having one or more laminated bodies each provided with a metal foil formed on one side of a resin film. The process includes coating a varnish containing a polyamic acid and a solvent onto the metal foil, holding the coated film, drying in which at least a portion of the solvent in the varnish is removed to form a layer composed of a resin composition, and forming the resin in which the layer composed of the resin composition is heated to form a resin film containing a polyimide resin. The conditions for each step from the coating up to the resin film-forming are adjusted based on a target for the content of metal elements in the resin film. |
