摘要:A printed circuit board (10) includes both high and low resistive value thick filmresistors interconnected by a copper film (18). To lower the contact resistance to thethick film resistors (12) of high value, each is provided at its ends with a termination(16A,16B) of a composition similar to that used for the low value resistors (16). Thisprovides a relatively low-resistance contact region which overcomes the difficulty that acopper thick film conductor has in making electrical connections to compositionsgenerally used for making high value thick film resistors. The compositions of high andlow resistivities are adapted to permit firing of both compositions in a single firing step.
