Abstract

Electron backscattered diffraction and energy dispersive X-ray spectroscopy has been performed on a plate-shaped phase formed through the reaction of Sn and Ni during extended thermal cycling tests, on ceramic capacitors have electroplated tin end terminations. The morphology is identical to that of a phase labeled NiSn(Sub3) by J. Haimovich (Welding Journal Research Supplement, 8 (1989)102). The phase is shown to have a stoichiometry, NiSn(Sub4), and a crystal structure isomorphous to PdSn(Sub4), PtSn(Sub4) and AuSn(Sub4) (Aba2, #41, oC20). The structure can also be described with the higher symmetry structure (Ccca, #68, oC20).
