Role of Zinc on Shear Property Evolution between Sn-0.7Cu Solder and Joints: 点击次数：; 发布时间： 2019-03-11; 发布时间：2019-03-11; 论文类型：会议论文; 发表时间：2011-04-15; 收录刊物：Scopus、SCIE、CPCI-S、EI; 卷号：16; 页面范围：807-811; 关键字：Sn-0.7Cu; zinc; shear; reflowing; microstructure; deposition; 摘要：Effect of zinc addition on the shear property evolution between Sn-0.7Cu solder alloy and their joints reflowed at 250 degrees C was investigated. The shear strength of Sn-0.7Cu/Cu joint was found to be higher than of Sn-0.7Cu solder alloy. Although a small addition of zinc element strengthened Sn-0.7Cu solder alloy, it decreased the shear strength of Sn-0.7Cu solder joints. Based on the fractography analysis and interfacial microstructure observation, it is proposed that the deposition of Cu-Zn intermetallic toward the interface during reflowing is largely responsible for the shear property evolution between the Sn-0.7Cu solder alloy and their joints.
