【摘要】 在Sn-Zn系无铅焊料的基础上,通过添加合金元素Al和P制备出不同成分的无铅焊料,研究了其无铅焊料的物理性能。结果表明:通过加入适量合金元素Al和P的Sn-Zn-Al-P系无铅焊料在基本上不影焊料响熔点的前提下,可以减小密度,降低成本,提高其导电性能和润湿性。更多还原

【Abstract】 The different weight percentages of Sn-Zn-Al-P lead-free solders were processed by adding alloying elements Al and P.The physical properties of Sn-Zn-Al-P lead-free solders were researched.The results show that appropriate amount of alloying elements Al and P of Sn-Zn-Al-P lead-free solders can reduce the density to cut the costs and improve conductive property and wetting ability without the effect of melting point of Sn-Zn-Al-P lead-free solders.更多还原
