Electrochemical corrosion behaviour of Pb-free SAC 105 and SAC 305 solder alloys: a comparative study

Electrochemical corrosion behaviour of Pb-free SAC 105 and SAC 305 solder alloys: a comparative study

Sn-Ag based solder alloy seems to be a promising lead-free solder for the application on electronic assembly. The corrosion behavior of different lead free solder alloys such as Sn-3.0Ag, Sn-1.0Ag-0.5Cu and Sn-3.0Ag-0.5Cu was investigated in 3.5% NaCl solution by potentiodynamic polarization and ele...
