| Abstract: | Thecommon problems of the varistorssilver paste is lower adhesion,uncover after the big current impact.The effects of the glassingredient, the additives and the silver powders on the properties of thevaristors was investigated. The glassingredients and the additives were proved to be an important effect on theadhesion and thebig current impact. The properties of the silver paste can be improved by using mixed silver powders, adding a additive and suitable glass powder. The silver paste printability, sheet resistivity, adhesion, wettability and soldering resistance can all meet the requirements. |
