Paper Abstract
Existing mini testers are mostly single axial without any active specimen alignment monitoring and adjustment capability. Fundamental investigation for packaging materials needs to be conducted in terms of constitutive laws, fracture process, failure quantities. For the first time, specimen alignment monitoring and adjustment was demonstrated for a single lap shear sample by the 6-axis mini tester and its associated alignment monitoring and control system, assisted by a high resolution laser moire measurement. This paper presents results for two types of polyimide films, one led-free solder alloy, some other conventional materials, and a flip-chip assembly subjected to a three points bending. Various mechanisms of deformation and failure for both the materials and structures have been discussed. In particular, a new constitutive model for polymer films is also proposed in this paper.
