Abstract:
Thick film conductive copper pastes that are lead-free and cadmium-free. The inventive copper pastes possess desirable characteristics, including good solderability, good wire bondability, a low firing temperature, and a wide temperature processing window, and provide excellent adhesion to a variety of substrates, including alumina and glass coated stainless steel substrates, as well as low resistivity, and a microstructure after firing that is dense and substantially free of pores.

Abstract:
Glass frits containing lithium are used in thick film palladium-silver compositions which after firing result in conductors or resistors that exhibit very low resistivity and TCR.
Power Surge Resistor Pastes Containing Tungsten Dopant
National Starch and Chemical Investment Holding Corporation - Wilmington DE
International Classification:
H01B 100 H01B 102 H01B 120 H01B 122
US Classification:
252514
Abstract:
Power surge resistor pastes comprising palladium/silver, glass and dopant(s) are described for use in the manufacture of power surge resistor devices employed for power surge protection applications. The resultant surge resistors are characterized in their ability to dissipate repeated voltage surges equal in voltage and duration to surges created by lightning with less than 0. 05% change in sheet resistance.
