Abstract
Ag participating the electrochemical migration (ECM) of Sn-Ag based alloys is still controversial. In this work,Ag+concentration in electrolyte layer and Ag distribution in dendrites formed during the ECM of 96.5Sn-3Ag-0.5Cu alloy were investigated using Inductively Coupled Plasma Source Mass Spectrometer and ScanningTransmission Electron Microscopy, respectively. Results show that Ag+can only be detected when Ag can re-lease from Ag3Sn during the anodic polarization of 96.5Sn-3Ag-0.5Cu alloy. Under such a condition, Ag couldalso be found in dendrites. Therefore, it can be concluded that Ag participates the ECM of 96.5Sn-3Ag-0.5Cualloy, but it is potential-dependent.
