Abstract
We apply this workflow in modeling and analyzing the evolution of stresses of solder joints arrays in the flip chip manufacturing process in microelectronics fabrication. We also conduct a variety of simulations of solder joints arrays, including large-scale (up to 1 billion of degree of freedoms) simulations on IBM Blue Gene/Q supercomputer, and perform scaling studies. We analyze the stress by tracking the evolution of stresses at critical regions with respect to time. We also present the utility of the proposed approach by demonstrating that qualitatively different stress concentrations are observed in a solder joint near the center of the array and in the corner of the array.
