Abstract :
A strain gauge on the PAQC (package assembly qualification & characterization) chip is used to make a comparison of mechanical stress over temperature between three different package types. The tape-ball grid array (tapeBGA), metalBGA, and ViperBGATM are assembled and stress tested as part of an ongoing reliability evaluation. Stress resistor values are sampled and compared, before production lots of each type are put through qualification testing. After qualification tests are completed, stress resistor values are sampled again and compared to the original data
