METHOD FOR THE MANUFACTURE OF PRINTED CIRCUIT BOARDS WITH EMBEDDED RESISTORS

摘要

A process is revealed whereby resistors can be manufactured integral with a circuit board by printing the resistors onto the insulative substrate. Uniformization of the insulative substrate through etching is discussed as a technique for improving the uniformity and consistency of the printed resistors. Trimming and baking are also disclosed as methods for adjusting and stabilizing the resistance of the printed resistors.
