摘要

While surface tensions of solid-vaporand solid-liquid interfaces are hard to estimateand control, the surface tension at the lastliquid-vapor interface, sigma sub LV , wasoriginally proposed to be correlated with excessGibbs energies of formation of liquid alloys, andlater its validity was successfully tested invarious binary alloys. In this study, a similarapproach is made to compare with experimentallymeasured surface tensions of Sn-based binary,ternary, and quaternary solder systems of currentinterest, and wetting properties such as spreadingarea and contact angle are explained through thesurface tension. Specific alloy systems studiedin this work are commercially available Sn-Bi-Pb,low-temperature solder Sn-Bi-In, and Sn-based lowPb-bearing four quaternary solders.
