AbstractThe intermetallic compound (IMC) formed between eutectic SnIn solder and single crystalline Cu substrate during reflow and solid-state aging was investigated precisely utilizing electron microscope. Two kinds of crystal structures with different morphologies were identified, which are Cu(In, Sn)(2) at the solder side and the Cu-2(In, Sn) at the Cu substrate side. The Cu(In, Sn)(2) layer with chunk-type morphology suffered spalling easily during slightly increased liquid soldering at 160 degrees C, and Cu-2(In, Sn) was in the form of duplex structure with coarse-grain and fine-grain sublayers. During solid-state aging at 60 degrees C, the morphology of fine-grain Cu-2(In, Sn) kept granule-type, while that of the coarse-grain Cu-2(In, Sn) was substrate-dependent with elongated morphology.
