WitrynaWe recently developed Cu-Zn alloy wetting layer for the SAC solder balls to improve the reliability. In this paper, IMC formation and solder joint reliability have been investigated in the solder joint between SAC solder balls and Cu-Zn alloy pads, and Cu pads were also used as a reference. Sn-4.0Ag-0.5Cu solder balls were used and the substrates … Witryna11 kwi 2024 · The electromigration reliability of Au/Pd(P)/Ni(P) surface finish in micro joints was investigated in this study. We found that the reaction of Pd(P) with molten Sn would yield a noticeable amount of (Pd,Ni)Sn 4 intermetallic compound (IMC) scattering in the Sn matrix after soldering reaction. Interestingly, upon electron current stressing, …
