Flame-proof flexible printed circuit board |
摘要 |
A flexible printed circuit board having excellent flame proofness and a very little danger of causing a fire can be produced by subjecting a substrate or an insulating film consisting of a flexible resin film to surface treatment to provide a surface tension of 36 dyne/cm or more and then forming a resin film containing a flame retardant on the treated surface of said substrate or insulating film.
