A numerical model is developed to predict the detailed thermomechanical response of a BGA assembly during reflow soldering. The governing coupled solid mechanics and heat diffusion equations are solved using a commercially available finite element package. Reported predictions illustrate the system`s sensitivity to both thermal and mechanical processing conditions, as well as component thermal properties. Specifically, assemblies with components of high thermal conductivity show the greatest sensitivity to mechanical loading conditions.
