    Sn-0.7Cu lead free solder has become an alternative material to replace Sn-Pb solder. However, it has the weakness of high melting point and poor corrosion behavior. Through the study, Sn-0.7-xZn microstructure and phase changes were studied through scanning electron microscope (SEM) and X-ray diffraction (XRD). SEM result shows microstructure Cu6Sn5 is precipitated with rod like shape while CuZn is shown in bump oval shape whereas compounds that presented are Cu6Sn5 and Cu5Zn8 as shown in the XRD analysis result.
