Titel
Thermal reliability assessment in SM- and COB-technology by combined experimental and finite element method
Abstract
The authors address the issue of thermo-mechanically stressed microelectronic assemblies. An approach combining finite element simulation and advanced in-situ measuring techniques is presented. Examples deal with the application of experimental methods such as micro moiré technique, speckle pattern photography and x-ray stress analysis in connection with numerical simulations. Problems of solder joint reliability are dealt with.
