Abstract
A few reliability evaluations indispensable for using Pb-free solder have not been investigated, especially the amount of data of joint reliability on Sn-Zn solder with Pb-free plated lead is less than other Pb-free solders. In this study, we measured pull strength for joint of Sn-8Zn-3Bi solder with various Pb-free plated leads and observed solder joints metallographically. And we suggest that the joint of Sn-Zn solder with Pb-free plated lead have sure reliability, which is higher than with Sn-Pb plated lead.
