Review on the Al2O3 nanoparticle reinforcement effect on thermal and mechanical properties of SAC alloys

This paper presents a short summery on the effect of the addition and doping of Sn-Ag-Cu or commonly known as SAC alloys with Aluminum oxide (Al2O3) nanoparticles. The paper introduce initially the background of the lead free solders as well as establish the concept of nanoparticle reinforcement composite lead free solder alloys. Then a short summery on the effect of the two nanoparticle reinforcement on the sac solder in the sections of Thermal properties and mechanical properties is presented. For instance some reported with Sn-0.3Ag-0.7Cu (SAC0307) when alloyed with 0.12 Al2O3 it showed an improved shear force of thermal cycling when it came to the mode of ductile fracture in comparison to the original alloy which possess a mode of fracture that presented a mixture between ductile and brittle.
