A Multi-Axial Thermo-Mechanical Fatigue Tester for Electronic Packaging Materials

Abstract

A multi-axial thermo-mechanical mini-fatigue tester has been developed at Wayne State University for investigating the behaviors of small specimens, particularly in the field of electronic packaging materials and structures. The testing and calibration of machine is described in this paper. Materials tested include a copper wire, two kinds of polyimide films, a lead-free solder alloy.
