中文摘要：
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-(1%-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.
