摘要
An autofocus Digital Image Correlation (DIC) workstation incorporating image stacking functionality was used to perform a thermo-mechanical deformation and strain analysis of controlled collapse chip connect (C4) bumps in two FC-BGA packages. Cross-sections through C4 bumped region were analysed through a temperature cycle from ambient temperature up to 100degreesC. Strain concentrations at the C4 layer-to-die interface are revealed. Aspects of recent advances in digital image correlation technology are described in the context of this study.
