Abstract
A method for selectively plating metal, such as copper, onto poly(phenylene sulfide) substrates is disclosed. In this method, a crystalline region and an amorphous region are created in a substrate. One method for creating these regions is to selectively crystallize a region in an amorphous poly(phenylene sulfide) substrate by heating it above its glass transition temperature. The surface of the substrate is then activated with an electroless plating catalyst such as palladium metal. After activation, a nitrosyl salt is introduced into the amorphous region of the substrate. The substrate is then immersed in an electroless plating solution containing the metal ions whereby metal selectively plates onto the crystalline region of the substrate.
