Effect of Added Ni Nanoparticles on the Microstructure and Mechanical Properties of Sn58Bi/Cu Solder Joints under Thermal Shock Conditions

Advanced Electronic Materials, EarlyView.
This article concludes that the microstructure as well as grain coarsening is suppressed and the growth of IMC layer is promoted in Sn58Bi/Cu solder joints versus Sn58Bi‐0.6 Ni/Cu solder joints after 1200 thermal shock experiments, while the mechanical properties of the solder joints are improved.
