Abstract

This research aims to develop a method for measuring small strains at minute area on an electronic packaging using digital image correlation. To this end, the systematic error in the measured displacement is corrected by using the relation between measured displacement and actual displacement. This relation is obtained by measuring rigid rotation and in-plane translation. The strain distribution with high spatial resolution can be obtained from the displacement distribution because the systematic error that affects the resolution of the strain is eliminated. This error elimination method is applied to the thermal strain measurement of a bimaterial which is composed of copper and steel. Results show that high spatial resolution strain distributions at minute area can be obtained by using this method.
