Abstract

An electromotive force in deformation of Pb free solder joint was generated and measured successfully by a thermo-couple. The method using the thermo-couple proposed in this study is combined with a conventional testing machine. Using the testing machine, both the load-deformation diagram and electromotive force were obtained at the same time. The peak value of electromotive force in tension and shearing increased linearly as the deformation speed increased. The electromotive force in shearing was smaller than the value in tension. This small electromotive force could be related to the small strain energy and results in weakness in shearing of solder joint.
