In this study, Sn.3.5Ag/SnO2 nanocomposite solders are developed. Composites with 0.7 and 1.0 volume percentage of tin oxide were synthesized through powder metallurgy route incorporating microwave assisted rapid sintering technique followed by hot extrusion. The extruded specimens were examined in terms of their physical and tensile properties. Tensile characterization studies revealed that 0.2% yield strength and ultimate tensile strength were increased significantly by addition of 0.7 volume percent of nano SnO2 particles. An attempt is made to correlate mechanical properties of Sn-3.5Ag with the presence of SnO2 particles at the nanometer length scale.
