ABSTRACT:
A method of manufacturing a printed wiring board on a cubically molded substrate enables formation of high-precision printed circuits fully compatible with the complex configuration of the cubic substrate. The manufacturing method includes initially forming a conductive layer on the surface of a cubic substrate followed by etching the conductive layer. The method includes the steps of forming electrodeposited resist on the conductive layer, exposing the electrodeposited resist to parallel light beams through a planar photomask, and etching the conductive layer to complete the formation of the printed circuit.
