ABSTRACT:
An apparatus and method for at least one of detecting and preventing burning of a PCB is disclosed. The method includes configuring a first comb array defined by a plurality of first fingers at a first potential; configuring a second comb array defined by a plurality of second fingers at a second potential different from the first potential; interlacing the plurality of first fingers defining the first comb array with the plurality of second fingers defining the second comb array embedded in a substrate; disposing the substrate with the PCB; and detecting a rise in leakage current between the first and second comb arrays indicative of a breakdown of the substrate.
