Molybdenum resistors - economic alternative for thick film technology

Parameters of improved, recently developed thick film resistors based on molybdenum oxide pastes were investigated. Resistors of aspect ratio 1:2 were printed on various substrates. AgPd, AgPt and Ag pastes were used for contacts preparation. Spread of fired resistance, TCR, long term stability, influence of contacts material, influence of thekind of substrate, under and overglaze were tested. Results were v ery prospective. Spread of as fired resistance is lowerthen 10 % in any case. TCR is dependent on sheet resistivity and is lower then 200ppm/K for all compositions.
