ABSTRACT:
A method of making capacitive/resistive devices provides both resistive and capacitive functions. The capacitive/resistive devices may be embedded within a layer of a printed wiring board. Embedding the capacitive/resistive devices conserves board surface real estate, and reduces the number of solder connections, thereby increasing reliability.
