Abstract

Electron backscatter diffraction (EBSD) technology combined with Orientation Imaging Microscopy (OIM) analysis method were employed to investigate the morphologies and orientations of Cu6Sn5 grains formed between Sn3.0Ag5.0Cu and polycrystalline copper, (001) (111) Cu single crystals under liquid-state condition. The reflow temperature was the main factor that influence the transformation of Cu6Sn5 grains from scallop-type to prism-type. The morphology for. the prism-type Cu6Sn5 grains formed on Cu single crystals arranged regularly, and their orientations had a strong dependence on the Cu substrates, the reason for which is the low misfit leading to the decreasing of surface energy.
