Abstract:
A process for manufacturing a 3-dimensional circuit board by electrophoretic deposition whereby a) providing the board with a conductive surface and b) applying a photoresist by electrophoretic deposition.
Abstract:
A process for promoting the adhesion of metal to thermoplastic substrates such as polyimides. The improvement comprises conditioning the substrate by treating with a lactone and aqueous rinse prior to subsequent steps of etching and deposition of a metal coating. Use of the conditioner promotes increased adhesion between the substrate and the metal without loss of the cohesive integrity of the substrate throughout subsequent processing steps.
