Abstract

Current stressing results in electromigration and thus separation of metal atoms in an alloy. The present study reports that current stressing also induces the supersaturation of alloying elements. An in situ scanning electron microscopy/energy-dispersive spectroscopy analysis revealed that the dispersed Sn phase of 95Pb–5Sn solder in a 95Pb–5Sn/63Sn–37Pb composite solder joint disappears under current stressing. The Sn concentration reached 9.3% near the cathode in a 95Pb–5Sn solder wire at a current density of 1 × 104 A cm−2.
