Effect of surface finishes on electromigration reliability in eutectic Sn58Bi solder joints
We studied the failure behavior induced by EM test on the SnBi solder joint. We evaluated the EM reliability of SnBi solder joint on various surface finishes. The Bi was segregated from cathode to anode side. The OSP surface finish showed longer time to failure than others.
