As solder bumps become increasingly miniaturized to meet the severdemands of future electronic packaging, it is important to consider whether the solderjoint size and geometry could become reliability issues and thereby affect implementationof the Pb-free solders. In this study, the effect of the solder bump size on the interfacialreaction between the solder and a substrate and the impact reliability using a miniatureimpact tester was investigated. Experimental results suggest that the solder bump sizecan influence the interfacial reaction and the impact reliability of the solder bump.

随着焊料凸点越来越小型化以满足未来电子封装的苛刻要求，重要的是要考虑焊点尺寸和几何形状是否会成为可靠性问题，从而影响无铅焊料的实施。在本研究中，利用微型冲击试验机研究了焊料凸块尺寸对焊料与基板之间的界面反应和冲击可靠性的影响。实验结果表明，焊料凸点尺寸会影响界面反应和焊料凸点的冲击可靠性。
