Experimental results showed that additions of Ag to Sn resulted in a continuous decrease in the Theta up to 3.5 wt.% above which the Theta value was increased. Increasing alloy temperature also decreased the Theta proportionally. Experimental results revealed that a correlation between the Theta, alloy composition and the alloy temperature exists which yielded an empirical model to predict the Theta at a given Ag content and temperature for a given Sn-Ag alloy. The empirical model predicts the Theta reasonably well with the present work and the other published works.eninfo:eu-repo/semantics/closedAccessSurface-TensionWetting BehaviorWettabilityRoughArticle10.1051/epjap/20111004872-s2.0-799596565611Q354WOS:000289624000016Q3
