摘要: 激光植球工艺在实际应用中存在焊球剪切强度低于标准的问题。使用Ф500 μm的焊球(Sn63Pb37)进行不同激光参数下的焊接试验,通过测量焊球剪切强度,找到激光高度、激光功率、激光作用时间的优化方向。

Abstract: Laser ball planting technology has the problem that the shear strength is lower than the standard value in practical applications. This experiment use Ф500 μm solder balls(Sn63Pb37) to laser ball planting with different process parameters, for example, laser height, laser power and laser time.We find the optimal direction of laser parameters by measuring the shear strength of the welded ball.

Key words: laser jet bumping, balls’shear strength, BGA
