摘要

A photograph artwork containing a one to one scale exact image of the circuit pattern to appear on a fabricated printed-wiring board is modified in a predetermined manner. This has the effect of equalizing the amount of metallic conductive circuits on a double sided printed wiring board or panel. The resulting board or panel is plated uniformly on both sides when passed through the electrodeposition cycle of a fabrication process.
