ABSTRACT:
A printed circuit board is formed from a metal-clad substrate by applying a solvent-free, non-dryable ink in a predetermined pattern on the substrate, dusting powdered resin over the surface, removing any resin powder not retained by the ink from the surface, heating the substrate having the ink powder thereon to a temperature so as to fuse the powdered resin to form a strippable resist, etching the uncoated portion of the metal laminate and stripping the resist subsequent to etching.
