Preparation of Lead-free Thick-film Resistor Pastes
The preparation of lead-free thick-film resistors are reported: using RuO2 and ruthenates as conductive particles, glass powders composed of B2O3, SiO2, CaO and A12O3 as insulating phase, adding organic matter which mainly consists of ethyl cellulose and terpineol to form printable pastes. Resistors were fabricated and sintered by conventional screen-printing on 96％Al2O3 substrates, and then sintering in a belt furnace. X-ray diffraction (XRD) and electron scanning microscopy (SEM) have been used to characterize the conductive particles. The resistors exhibit good retiring stability and low temperature coefficient of resistance. Sheet resistance spans from about 80 Ω/□ to 600 Ω/□. The resistors prepared are qualified for common use.
