Abstract
Disclosed is a method of making a printed circuit board by exposing in a circuit pattern the polymeric surface of a conductive substrate coated with a polymer selected from the group consisting of polyimides, polyamide-imides, polyester-amide-imides, polysulfones, polyphenylene sulfides, and polyphenylene oxides, to an ion beam at an energy of about 50 KeV to about 2 MeV and a fluence of about 10.sup.15 to 10.sup.18 ions/cm.sup.2. The surface is then wet blasted and the portions of the polymeric surface that have been exposed to the ion beam are electrolessly plated with a metal such as nickel or copper. Also disclosed is a coated substrate comprising a metal or conductive surface and an imide polymeric coating on the surface which can be electrophoretically deposited, a portion of which has been exposed to an ion beam.
