Abstract
The ternary Sn-1.0Ag-0.5Cu (SAC105) solders doped with a minor addition of Fe (0.1, 0.3 and 0.5 wt.%) have been shown to demonstrate excellent mechanical thermal cyclic reliability. To complement the mechanical performance, the electrical resistivities of SAC105, SAC105-0.1Fe, SAC105-0.3Fe, and SAC105-0.5Fe bulk solder alloys were also characterised after thermal aging. Results showed that the overall resistivity decreased by up to 13% after the thermal aging process. Meanwhile the electrical resistivity for 0.1 wt.%, 0.3 wt.%, and 0.5 wt.% Fe-bearing SAC105 solder alloys decreased by 25%, 11%, and 17% respectively, showing a rather stable reduction in resistivity. This can be correlated to the stabilisation of the microstructure of the Fe-added SAC 105 after thermal aging.
