针对低温银浆固化后出现的断裂失效现象，通过增加烘烤时间、提高烘烤温度、高温高湿下处理、冷冻情况下折叠破坏以及采用溶剂腐蚀等方法进行实验研究。采用放大镜观察以及电阻变化测试，确认了失效原因在于某些溶剂再次溶解了浆料中的树脂，而后出现二次固化收缩，从而出现线路断裂失效现象。
針對低溫銀漿固化後齣現的斷裂失效現象，通過增加烘烤時間、提高烘烤溫度、高溫高濕下處理、冷凍情況下摺疊破壞以及採用溶劑腐蝕等方法進行實驗研究。採用放大鏡觀察以及電阻變化測試，確認瞭失效原因在于某些溶劑再次溶解瞭漿料中的樹脂，而後齣現二次固化收縮，從而齣現線路斷裂失效現象。

The low temperature silver paste fracture failure after curing were studied by increasing the baking time, improving the baking temperature, processing on the condition of high temperature and high humidity, folding damage under freezing as well as the solvent corrosion. Through an optical magnifier observation and resistance test, the reasons for fracture failure of silver paste were confirmed that a certain solvent redissolved paste resin, result in the twice curing shrinkage and arising line failure phenomenon.
