摘要 选用Sn64Bi35Ag1、Sn64.7Bi35Ag0.3和Sn99Ag0.3Cu0.7三种不同的钎料进行回流焊焊接试验,研究高Bi元素、低Ag元素钎料及低Ag钎料对Sn基钎料焊点微观组织及剪切性能的影响。结果表明:各焊点界面处均生成了一层扇贝状的Cu6Sn5金属间化合物,在含Bi元素的钎料焊点中,Bi元素在焊点界面及内部聚集,导致界面处金属间化合物层的厚度增加,大量富Bi相呈脆性,降低钎料中的Ag含量对焊点中Bi元素的富集现象有减弱作用。Sn99Ag0.3Cu0.7钎料焊点界面处的金属间化合物层厚度最小,且焊点内部形成了细小的Ag3Sn相颗粒,共晶组织呈均匀分布,使得焊点剪切性能最优,其剪切强度达20.4 MPa。

Abstract: Three different solders, Sn64Bi 35Ag1, Sn64.7Bi 35Ag0.3 and Sn99Ag 0.3Cu0.7, were selected for the reflow welding test. The effects of high Bi, low Ag and low Ag solders on microstructure and tensile shear properties of Sn-based solder joints were investigated. The results show that a scallop-like Cu6Sn5 intermetallic compound is formed at the interface of each solder joint. In the solder joint containing Bi, the accumulation of Bi at the interface and inside of the solder joint leads to the increase of the thickness of the intermetallic compound layer at the interface, and a large number of Bi-rich phases are brittle. The decrease of Ag content in the solder weakens the enrichment of Bi in the solder joint. The thickness of intermetallic compound layer at the interface of Sn99Ag0.3Cu0.7 solder joint is the smallest, and fine Ag3Sn phase particles are formed in the solder joint. The eutectic structure is uniformly distributed, which makes the shear performance of the solder joint optimal, and the shear strength reaches 20.4 MPa.
