| 中文摘要: |
| 附着力低和大电流冲击时揭盖是压敏银浆经常出现的问题。研究了玻璃成分、添加剂及银粉对压敏电阻性能的影响。结果表明，玻璃的化学成分及银浆的添加物对银层的附着力和大电流冲击有重要影响。优化配方使用混合银粉，加入添加剂，选用合适的玻璃粉，所得银浆料的印刷性能、方阻、附着力、与焊料的润湿性及耐焊性等各项指标符合要求。 |
| 英文摘要: |
| The common problems of the varistors silver paste is lower adhesion, uncover after the big current impact. The effects of the glass ingredient, the additives and the silver powders on the properties of the varistors was investigated. The glass ingredients and the additives were proved to be an important effect on the adhesion and the big 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. |
