Abstract
Abstract Poly (arylene sulfide) substrates are laser treated, i.e., treated with a beam of laser radiation, and then contacted with plating solution. In a specific embodiment, laser treatment imparts a specific pattern on the poly(arylene sulfide) substrate, which is then subjected to an electroless plating solution to give a printed circuit board.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
56 words
A method for plating a poly(arylene sulfide) substrate comprising: a) contacting at least one surface of said poly(arylene sulfide) substrate in particular a poly(phenylene sulfide) substrate with a beam of laser radiation of sufficient intensity to render the surface of the substrate water-wettable, and b) contacting the laser treated poly(arylene sulfide) substrate with a plating solution.
Claim 2
Independent Claim
56 words
A method for plating a poly(arylene sulfide) substrate comprising: a) contacting at least one surface of said poly(arylene sulfide) substrate in particular a poly(phenylene sulfide) substrate with a beam of laser radiation of sufficient intensity to render the surface of the substrate water-wettable, and b) contacting the laser treated poly(arylene sulfide) substrate with a plating solution.
