A lower –melting – point solder alloy composition Sn42-Bi57.3-Zn0.7 has been studied by Differential Scanning Calorimetric (DSC), a large portion of the alloy melts sharply at a approximately 136˚C, the melting point of Sn-Bi , Sn- Zn eutectic alloy .The produce alloy was analyzed by XRD and optical microscopy for microstructure characterization .The hardness of alloy has been tested and was found of a value 10HRB as a ductile form .
