Effect of Lead Free Glass Frit Compositions on Properties of Ag System Conductor and RuO 2 Based Resistor Pastes

Abstract: The effect of lead free glass frit compositions on the properties of thick film conductor and resistor pastes were investigated. Two types lead free frits, HBF-A(without ) and HBF-B(with ) were made from , , , CaO, MgO, , , ZnO, MnO, , . And Ag based conductor pastes and based resistor paste were prepared by mixed with these frits and functional phase(Ag and ), and organic vehicle. The properties of thick film conductor and resistor sintered at were studied after printing on substrate. The morphology of the sintered films surface were SEM and EDS were carried out to analysis the chemical composition on resistor surface and state of Ru atom in frit matrix.
