Abstract
A method of manufacturing and monitoring the manufacture of a thick film circuit board device. The method includes the steps of forming a resistive layer in a prescribed pattern on an insulative base board, forming a first conductive layer on the insulative base board adjacent to the resistive layer with a gap of predetermined width therebetween and forming a second conductive layer in the gap and overlapping a portion of the resistive layer and the first conductive layer for establishing electrical contact between the resistive layer and the first conductive layer.
