端電極用低溫環氧導電漿
.png)
產品描述
LT7000、EP9130及JC6TY系列是一款熱固形環氧樹脂與導電粒子組合物，應用於被動元件的端電極以提供好的耐彎曲特性，一般高溫端電極材料，雖具有好的耐熱性與性能穩定性，但面對輕薄短小及撓曲彎折的應用需求，容易發生元件斷裂問題。因此開發以樹脂本體的導電漿料，提供陶瓷元件更好的抗撓曲性，降低彎折造成的應力破壞。藉由配方的設計使的高分子樹脂組成的導電漿料仍能具可電鍍性。
產品特徵
-
較低的熟成溫度同時具有優異的導電性能取代原本高溫燒結的製程
-
接著強度穩定性高，表面電鍍鎳層接著介面穩定性佳
-
適用於常溫保存，提供客戶好的儲存條件
-
沾銀平整度優異，可減少後續製程的高低段差
-
JC6TY系列有更好的耐濕性和可靠度。
