Thermal testing | 23 June, 1999

Hi Could anyone tell me where i can find information, in the literature or on the Web, concerning measurements of temperature distribution, expansion, stresses in the substrate and heat sink and on the interface between them, that is all the range of thermal-mechanical testing of semiconductor assembly. Thanks, Stan

A good place to start is the EIA/Jedec Standard (EIA/JESD 51-2) Integrated Curcuits Thermal Test Method Environment conditions - Natural Convection (Still Air). This is a good componet level source for thermal testing. EIA/JESD 51-1 and 51-3 may also help you out.
