摘要

The series of lead-free thick film resistors were elaborated by Institute of Electronic Materials Technology (ITME) in Warsaw. The paper presents investigations of two pastes: R-100 with resistivity 100 Omega/square and R-100 k with resistivity 100 kOmega/square The pastes were screen printed on alumina substrate with AgPd lead-free terminations. Then fired at several temperatures in the range 750-950degC for 10 minutes and 6 hours at highest temperature. Sheet resistivity and thermal coefficient of resistance (TCR) were measured. X-ray diffractograms were taken. The conductive phase that was RuO2 maintained initial crystal structure regardless firing conditions. No devitrification was observed in lead-free resistors glasses. The lattice constants of RuO2 were uniform at temperatures over 800degC. The resistors matched the desired resistivity and the TCR was least temperature dependent at the firing temperatures around 850degC.
