At present, the electronic packaging industry is actively searching for lead‐free (Pb‐free) solders due to environmental concerns over Pb‐containing solders. For a successful transition to Pb‐free manufacturing in electronics assembly, it is critical to understand the behavior of Pb‐free solders. We
## Abstract Corrosion properties of three different Sn‐Ag lead free solder alloys have been investigated in 0.3 wt% Na~2~SO~4~ solution as corrosive environment. As cast solder alloy was analyzed by X‐ray diffraction (XRD) and scanning electron microscopy (SEM). Volume fractions of the Ag~3~Sn in t
Multiaxial fatigue tests were conducted on Sn-3.5Ag solder specimens under axial/torsional loading at room temperature. It was found that the ratcheting strain increased while the fatigue life decreased with the increase of axial stress and shear strain amplitude. A power relationship of ratcheting
A ZrO 2 nanoparticles strengthened lead-free Sn-3.5Ag-ZrO 2 solder was prepared by mechanically stirring ZrO 2 nanoparticles into the molten melt of eutectic Sn-3.5Ag alloy. The influence of ZrO 2 nanoparticles on the eutectic solidification process, in particular the formation of Ag 3 Sn intermetal
