... management task for the artillery application challenging. The ability to accurately analyze these designs requires the use of fully coupled thermal-stress transient-analysis with accurate material properties over the full temperature range. To highlight the thermal-stress transient effects, the potted...

.... The large temperature difference between the substrate and chip produced a high thermal stress, and the large bonding force generated a high mechanical stress. The thermal and mechanical stresses were the reasons for warpage in a COG module. For the high reliability, the design and bonding process...

.... These cracks could be a path for moist gas to diffuse into the initiator, potentially leading to bridge-wire degradation and late-fire or no-fire initiator failure. Previous research has shown that cracking may be caused by thermal stresses induced by the GTMS formation process. The goal of this research...

...M. A. Neidigk; Y.-L. Shen The generation of thermal stresses is a major cause for mechanical failure in encapsulated electronic components. In this study numerical modeling is employed to analyze thermal stresses in a high-voltage transformer encapsulated with filled epoxy. The transformer assembly...
