| 摘 要： | 目的研究Sb和Bi元素对Sn-22Sb钎料显微组织的影响。方法制备了(Sn-22Sb)-xBi和Sn-xSb钎料合金,并分别采用差热分析和X射线衍射仪,分析了材料的熔化特征和物相。结果结果表明:Sn-22Sb钎料合金主要由灰色的β-Sn和白色块状的Sb2Sn3构成;少量的Bi使得Sn-22Sb钎料合金中Sb2Sn3金属间化合物逐渐细化和均匀化,数量却急剧增加;大量添加Sb后,使得Sn-22Sb钎料合金几乎全部变为粗大的块状β-SnSb组织,钎料合金的开始熔化温度有所提高。结论通过添加其他合金元素,降低Sn-50Sb钎料液相线温度,使其有望应用于二次回流焊。

| Abstract: | Objective To investigate the effects of Sb and Bi on the microstructure of Sn-22Sb Solder alloy. Methods （Sn-22Sb）-xBi and Sn-xSb solder alloys were prepared. The melting behavior and phase were analyzed by differential scanning calorimetry （DSC） and X-ray diffraction （XRD）, respectively. Results Sn-22Sb solder alloy was mainly composed of gray 13-Sn and white block Sb2Sn3. A small amount of Bi made the microstructure of Sb2Sn3 intermetallic compound in Sn-22Sb solder alloy fine and homogenized. Thick massive β-SnSb could be found in Sn-50Sb solder alloy, and the initial melting temperature of Sn-50Sb solder alloy increased. Conclusion The liquidus temperature of the Sn-50Sb solder was reduced by adding other alloying elements, leading to possible application in secondary reflow soldering. |
