alternative lead-free alloys for replacing lead-based solders is a global demand. Despite
numerous studies on Sn-based lead-free solders in recent years, there is not yet a standard
solder alloy able to cover the spectrum of properties furnished by the classic Sn-Pb alloy. In
this sense, particular lead-free alloys compositions have been suited for specific needs and
the options have been broadening when elements other than tin are used as the base …
