Description

Corrosion behaviour of Sn-0.7Cu solder alloy was evaluated by conducting potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The solder was polarized under the scan rate of 1.0 mV/s and with the scan range from -2 to 1 VSCE. EIS test was performed at the frequency of 10000 Hz to 0.1 Hz. The oxide layer was found on the surface of solder by post-corrosion characterization. XRD results indicate that the main corrosion products formed on the solder after both corrosion tests were tin oxide such as SnO and SnO2. Porous rod-like structure of corrosion product was observed under morphology analysis of Sn-0.7Cu solder. The corrosion product was represented as tin oxide which matched with the result of XRD.
