WebComposites of SC solder reinforced with 0, 0.25, 0.5 and 1 wt.% of TiO 2 nanoparticles were fabricated using a mechanical technique. With increased addition of TiO 2 nanoparticles, the SC nano-composite solder was found to have a slightly lower melting temperature. The addition of TiO 2 nanoparticles can also effectively refine the microstructure as so β-Sn … Web202461 the failure behaviors of in48sn solder ball joints under various strain rate loadings were investigated with both experimental and finite element modeling study. the bonding force of in48sn solder on an ni plated cu pad increased with increasing shear speed, mainly due to the high strainrate sensitivity of the solder alloy. Lee mas WebA composite lead-free solder alloy composition having a nano-particles is provided and includes 40.0-60.0 wt% In, 0.01-2.0 wt% nano-particles and the remaining is Sn.
