Electronic assembly technology is in the transition from traditional tin-lead to lead-free. In comparison with Sn-Pb solders, high melting point and poor wettability of the lead-free solders lead to great challenge in many aspects. It has been accepted that inert N2 atmosphere can improve the wettability and reliablity of solder joints. The focus of this study is to investigate the reliability of...
Lead-free solder alloys are more easily oxygenized and have poor wettability compared to traditional Sn-Pb solder alloys, which affects solder joints reliability. Ar is the most plentiful rare inert gas. It has been accepted that, in Ar atmosphere, the oxidation of lead-free solder joints can be prevented and the wettability of lead-free solder joints can be improved. To date, however, few systemic...
