THIN FILM-LAMINATED POLYIMIDE FILM AND FLEXIBLE PRINTED WIRING BOARD |
摘要 |
<p>The thin film-laminated polyimide film contains a substrate film and a thin film layer formed at least on one surface of the substrate film. The substrate film is made of a polyimide film showing a degree of curl after a heat treatment at 300°C of not more than 10%. Use of this thin film-laminated polyimide film as a substrate of electronic parts such as solar battery, capacitor and the like exposed to high temperatures prevents easy development of warpage and distortion during production, and can improve quality and yield of electronic parts.</p> |
