摘要

研究了Cu@Sn@Ag （CSA）芯壳颗粒对Sn-3.0Ag-0.5Cu （SAC305）焊点组织、腐蚀行为和力学性能的影响。研究表明，CSA颗粒可以细化焊点的晶粒。SAC305 - 0.05 wt% CSA焊点的抗拉强度最大，比原始焊点SAC305高出17.10 %。盐水浸泡腐蚀试验表明，随着时间的延长，焊点的力学性能逐渐恶化，断裂方式由延性向脆性转变。经过30天的盐水浸泡，CSA颗粒保持球形，阻止了Cl的进一步渗透。此外，电化学测试获得的极化曲线和电化学阻抗谱（EIS）数据表明，含有CSA颗粒的焊点具有较低的腐蚀电流密度、较大的半圆直径和较高的总阻抗值。电化学测试后的腐蚀产物的扫描电镜（SEM）图像和三维形貌表明，含有CSA颗粒的接头的腐蚀产物分布更均匀，密度更大，粗糙度降低，最大轮廓高度减小。

Effects of Cu@Sn@Ag core-shell particles on microstructure, corrosion and mechanical properties of SAC305 solder joint

This study investigated the impact on the microstructure, corrosion behaviour and mechanical properties of Sn-3.0Ag-0.5Cu (SAC305) solder joints of Cu@Sn@Ag (CSA) core-shell particles. The study revealed that the grain in the solder joints can be refined by CSA particles. SAC305–0.05 wt% CSA solder joints exhibited the greatest tensile strength, surpassing the original solder joints (SAC305) by 17.10 %. Saltwater immersion corrosion tests revealed the mechanical properties of solder joints gradually deteriorated with age, with the fracture mode changing from ductile to brittle as the immersion period increased. After 30 days of saltwater immersion, the CSA particles remained spherical, preventing further penetration of Cl. Furthermore, polarisation curves and electrochemical impedance spectroscopy (EIS) data obtained from electrochemical testing revealed the solder joints containing CSA particles exhibited lower corrosion current density, larger semi-circular ring diameters and higher total impedance values. Scanning electron microscopy (SEM) images and 3D morphology of corrosion products after electrochemical testing showed that corrosion products on joints containing CSA particles exhibited more uniformly distributed and denser, with reduced roughness and maximum contour height.
