Abstract:
An additive process for making printed circuit boards utilizing aqueous alkaline strippable resists, in which a suitable insulating substrate is patterned with the resist, the resist-patterned substrate catalyzed to electroless metal deposition, the resist then stripped completely from the substrate, utilizing an aqueous alkaline solution, preferably containing a reducing agent, and the electroless metal then deposited over the areas of the substrate catalyzed in the desired pattern.
