Temperature coefficient of resistance controlling films

Image Number 2 for United States Patent #5366813.

A conductor runner composition is disclosed for using combination with resistors to limit and control the temperature coefficient resistance tracking of the resistors over varying temperatures. The conductor runner composition includes less than 60 weight percent silver powder which limits the amount of silver diffusing into the resistor at the resistor/conductor termination and thus reduces the effect of resistor/conductor interactions on the temperature coefficient of resistance of a resistor. The conductor has an extremely low TCR and resistivity combination.
