Abstract

Abstract: Using superfine silver powder as conductive filling phase, the effects of morphology and dosage of four different kinds of silver powders on rheological properties, developing resolution and electrical properties of photosensitive conductive silver paste were studied. The results show that the smaller the particle size of silver powder in the silver paste system, the stronger the thixotropy of the paste, the higher the accumulation density of silver powder is easy to form a dense sintering conjunctival layer, good electrical conductivity, the minimum square resistance of silver paste can reach 3.1 mΩ/□. The selection of silver powder with high density, low specific surface area, high dispersion, uniform distribution and high surface smoothness is helpful for the fabrication of high resolution electrode. Considering the electrode resolution and conductivity of photosensitive conductive silver paste comprehensively, the requirements can be met when the mass fraction of silver powder is 80%.
