Measuring intrinsic elastic modulus of Pb / Sn solder alloys

  title={Measuring intrinsic elastic modulus of Pb / Sn solder alloys},
  author={Cemal Basaran and Jianbin Jiang},
Young’s modulus (E) values published in the literature for the eutectic Pb37/Sn63 and near eutectic Pb40/Sn60 solder alloy vary significantly. One reason for this discrepancy is different testing methods for highly rate sensitive heterogeneous materials, like Pb/Sn alloys, yield different results. In this paper, we study different procedures used to obtain the elastic modulus; analytically, by single crystal elasticity and experimentally by ultrasonic testing and nanoindentation. We compare… CONTINUE READING
