| 摘 要： | 以Sn-3．5Ag-0．7Cu焊料为母合金，探讨了微量稀土元素Ce对Sn-Ag—Cu合金的电导率、润湿性以及力学性能的影响．研究表明：添加Ce对焊料的电导率的影响不大，对合金的润湿性和力学性能的影响较大．当w（Ce）=0．05％时，焊料合金的综合性能较好．

| Abstract: | The influence of rare earth element Ce on the conductivities, wetting and mechanical properties of Sn-3. SAg-0.7Cu solder has been studied. It shows that the doping of Ce has a little effect on the conductivity, but great effect on the wetting and mechanical properties of the Sn-Ag-Cu alloy. The solder has a superior comprehensive performance with the addition of 0.05,% Ce. |
