摘要:
A bonding wire comprising a core and a coating layer formed on the core, wherein the coating layer is formed from a metal having a higher melting point than the core, and further has at least one of the following characteristics; 1. the wet contact angle with the coating layer when the core is melted is not smaller than 20 degrees; 2. when the bonding wire is hung down with its end touching a horizontal surface, and is cut at a point 15 cm above the end and thus let drop onto the horizontal surface, the curvature radius of the formed arc is 35 mm or larger; 3. the 0.2% yield strength is not smaller than 0.115 mN/μm2 but not greater than 0.165 mN/μm2; or 4. the Vickers hardness of the coating layer is 300 or lower.
摘要(中):
一种接合线,其包括芯和形成在所述芯上的涂层,其中所述涂层由具有比所述芯更高的熔点的金属形成,并且还具有以下特征中的至少一个; 当芯熔化时与涂层的湿接触角不小于20度; 2.当接合线悬挂时,其端部接触水平表面,并在端部上方15厘米处切割,因此落在水平面上,所形成的弧的曲率半径为35毫米或更大; 0.2%的屈服强度不小于0.115mN / m 2,但不大于0.165mN / m 2。 或4.涂层的维氏硬度为300以下。
