Abstract : The domain of electronics undergoes continuous development to meet consumer demands while keeping up with "Moore's law". One of the approaches to meet these requirements is the use of multiple die in a single packaging module with a thinner package thickness. This research is a comparative study that evaluates the thermo-mechanical stresses developed in the single die, multi-chip and stack die packages. In this research, warpage measurement and bend tests were used to quantify the effects of stresses induced in these packages. The warpage displacement analysis showed package two die side by side with thicker mold compound thickness had the least amount of out of plane displacement compared to other package designs. In the cyclic four point bend test, all package recorded life were long enough to not affect functionality in field. However, solder cycles to failure did decrease in a side by side package due to increased package stiffness.
