| 中文摘要: |
| 针对膜片开关银浆固化后偶尔出现的银线变色断线现象进行分析。通过电镜观察，推测失效原因在于膜片开关生产封装过程中引入的有机物污染腐蚀银线路，从而出现银线变色断线，导致线路失效。 |
| 英文摘要: |
| Color break phenomenon analysis of membrane switch paste after curing occasional silver wire. By electron microscopy, it was inferred that the reason for the failure of the membrane switch production and packaging process introduced organic pollution corrosion silver line, which appears discolored silver wire breakage, resulting in line failure. |
