摘要:The growth kinetics and morphology of the interfacial intermetallic compound (IMC) Cu6Sn5 between Sn-3Ag-0.5Cu-xFe (x= 0, 0.5wt.%, 1wt.%) composite solders and Cu substrate during aging were investigated in the present work. The Sn-Ag-Cu-Fe/Cu solder joint were prepared by reflowing for various durations at 250 degrees C and then aged at 150 degrees C. The Fe element tended to suppress the growth of the Cu3Sn layer during solid-state aging. However, the total thickness of IMCs (Cu6Sn5 + Cu3Sn) for the composite solders with Fe particles was similar to that for SnAgCu without Fe particles.
