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, … Witryna25 kwi 2024 · The ramp-down step is the dominant phase influencing the final stress formations in the bonds. The results show an average of >30% decrease in the stress levels in Cu 3 Sn layer (IMC) when the bonding temperature is brought down from 320 °C to 200 °C, thus demonstrating the importance of low-temperature SLID process.
