Abstract
In this study, the average particle size of silver powder was 2㎛, 7㎛, and a mixture of these (50:50wt%), three kinds of silver pastes were prepared. In addition, as a result of examining the viscosity and viscoelasticity of the three silver pastes, TGA measurement, resistance change according to strain, and change in surface structure of the electrode, the following conclusions were obtained. Summarizing these results, it was found that it is most desirable to have a particle size of about 2㎛ in order to minimize the change in resistance due to strain.
