The paste was composed of 30wt.% to 90wt.% organic vehicle and 10wt.% to 70wt.% functional phase precursor (silver methylcarbamate). After the paste was sintered, films with thickness of 4.50μm to 12.70μm were obtained, in which the elemental percentage of silver varied from about 5wt.% to above 99wt.%. Experiments showed that both the electrical conductivity and the elemental percentage were mainly affected by the initial silver content in the paste and the parameters of the sintering process. For given sintering conditions, higher initial silver content led to higher elemental percentage of silver, improving the electrical conductivity of the thick film. The conditions of the sintering process had a significant influence on the evaporation and decomposition rates of the paste components, the elemental percentage of silver, and the microstructure of the thick film. Higher temperatures, longer times, lower heating rates, and more oxygen-rich sintering atmospheres were found to accelerate the evaporation and decomposition and increase the elemental percentage of silver, both of which served to enhance the electrical conductivity. For initial silver contents less than about 10wt.%, the lowest electrical resistivity of the thick film only reached the order of 10−4Ωcm, irrespective of the sintering conditions. For contents between 10wt.% and 25wt.%, it was possible to attain lowest resistivity values on the order of 10−5Ωcm. Above 25wt.%, the lowest resistivity could reach 10−6Ωcm, comparable to that of bulk silver.
