通过实验测定Sn-Ag-Sb及Sn-Zn-In系列合金的润湿角,进行了润湿性研究,发现Sn-Ag-Sb及Sn-Zn-ln系焊料存在润湿性差的缺点,通过添加低表面张力的金属或稀土元素可在一定程度上降低润湿角,能提高润湿性。
The wetting angles of Sn-Ag-Sb and Sn-Zn-In alloys were determined by experiments and the wettability of Sn-Ag-Sb and Sn-Zn-In alloys was investigated. Adding a low surface tension of metals or rare earth elements can be to some extent reduce the wetting angle, can improve the wettability.
