Method for improving the inspection of printed circuit boards

An improved method is provided for the visual inspection of printed circuit boards to determine the continuity or discontinuity of the circuits. In the method the circuit boards are treated in an electrolytic bath to cause an electrochemical change in the color of the continuous circuits versus the...
