In this study, two silver pastes were developed, with the particle size of silver powder, that is, the average particle size, 2㎛ and 7㎛. For the silver paste developed in this way, viscosity and viscoelasticity, TGA measurement to check the presence or absence of residual solvent after curing, resistance change according to strain, and electrode surface structure change were reviewed. 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.
