Further Observation on Tin Whisker from Electroplated Sn-Mn Alloy
Tin whiskers from Sn-(0-49 wt％)Mn alloy electroplating on polished mild steel were examined with FEG-SEM with EDX. The raw materials were Hull Cell samples kept in an office ambient with different storage time, up to 240 h. It is found that, depending on Mn content and plating microstructure, Sn-Mn alloy shows various types of whiskering. Except for the whisker forest found previously in Sn-20Mn, there exists another in Sn-(l％-5％)Mn. The latter also has a very short incubation time, less than 4 h. Another interesting finding is that one type of whiskering with surface cap supports an established model.
