目的 制备一种新型低银亚共晶Sn-0. 45Ag-0. 68Cu-X(SAC-X) 无铅钎料,并对其综合性能进行探究。方法 参照国家标准,对其漫流性、润湿性及力学性能进行了测试,并与Sn-37Pb,Sn-0. 7Cu,Sn-3. 5Ag-0. 6Cu 钎料进行了对比。结果 4 种钎料漫流性和润湿性大小依次为:Sn-37Pb,Sn-3. 5Ag-0. 6Cu,SAC-X,Sn-0. 7Cu,其中SAC-X 钎料铺展率达78. 5%,润湿时间为1. 3 s,最大润湿力为3. 18 mN;SAC-X 钎料抗拉强度(40 MPa) 与高银Sn-3. 5Ag-0. 6Cu 钎料(44 MPa) 相差不大,但延伸率是高银Sn-3. 5Ag-0. 6Cu 的1. 89 倍。结论 低银SAC-X 钎料综合性能优良,与Sn-3. 5Ag-0. 6Cu 钎料相差不大。 |
英文摘要: |
A new type of low-silver hypoeutectic Sn-0. 45Ag-0. 68Cu-X (SAC-X) lead-free solder was prepared to investigate its integrated performance. The flowing property, wettability and mechanical properties of the new type of solder were tested according to the national standards, and compared with those of Sn-37Pb, Sn-0. 7Cu and Sn-3. 5Ag-0. 6Cu solders. The flowing ability and the wettability of the four typical solders both followed the order of Sn-37Pb, Sn-3. 5Ag-0. 6Cu, SAC-X and Sn-0. 7Cu. The spreading rate of SAC-X solder reached 78. 5%, the wetting time was 1. 3 s, and the maximum wetting force was 3. 18 mN. The tensile strength of SAC-X solder (40 MPa) was close to that of Sn-3. 5Ag-0. 6Cu solder (44 MPa), but its elongation rate was 1. 89 times that of Sn-3. 5Ag-0. 6Cu solder. Low-silver SAC-X solder had good comprehensive performance, which was close to that of Sn-3. 5Ag-0. 6Cu solder. |
