| 摘 要： | 阐述了无铅钎料合金设计的原则, 讨论了合金相图及其计算在无铅锡基钎料合金设计中的作用. 利用相图计算技术筛选了可能代替Pb-Sn共晶钎料合金的Sn-Zn-In三元(x(Zn)＜0.11, x(In)=0.10～0.14)和Sn-Zn-In-Ag四元(x(Sn)=0.800, x(In)=0.090, x(Zn)=0.075, x(Ag)＜0.049)无铅锡基钎料合金. 初步讨论了用相图计算技术在富Sn四元Sn-Zn-In-Ag无铅钎料合金基础上, 添加Bi, Sb等低熔点金属和微量Ce, La等稀土元素以降低贵金属In和Ag的含量, 进一步提高无铅锡基多元合金钎料的综合性能和性能价格比.

| Abstract: | The principles for lead-fsee solder alloy design and the importance of phase diagram study as well as the calculation of phase diagram(CALPHAD) approach in the lead-free solder alloy design are discussed. Based on CALPHAD approach two potential lead-free solder alloys, i.e., the Sn-Zn-In(x(Zn)<0.11, x(In)=0.100.14)ternary alloy and the Sn-Zn-In-Ag(x(Sn)=0.800, x(In)=0.090, x(Zn)=0.075, x(Ag)<0.035)quaternary alloy are recommended as lead-free solder alloy instead of the Pb-Sn eutectic solder alloy. The further work for decreasing the content of In and Ag in Sn based Pb-free multi-component alloy with excerlent properties is brief discussed. |
