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: 15
Claim 1
Independent Claim
50 words
A method for plating a poly(arylene sulfide) substrate comprising: (a) contacting at least one surface of said poly(arylene 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
50 words
A method for plating a poly(arylene sulfide) substrate comprising: (a) contacting at least one surface of said poly(arylene 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 3
Dependent Claim
30 words
A method according to claim 1 wherein said beam of laser radiation has an intensity of at least 1×10 8 joules/sec/cm 2 up to about 5×10 9 joules/sec/cm 2 .
