Interfacial reactions in the Sb-Sn/(Cu, Ni) systems: Wetting experiments

► Sb-Sn alloys are used as high temperature lead-free solders. ► Sb-Sn alloys have good wetting properties on Cu and Ni substrates. ► Interfacial reactions and products are important for joint properties. ► Interfacial reactions/products data can be used to study the phase diagrams.
