Thermomechanical reliability assessment in SM- and COB-technology by combined experimental and finite element method
In the paper, the authors address the issue of thermo-mechanically stressed microelectronic assemblies. An approach combining finite element simulation and advanced in-situ measuring techniques are presented. Examples given in the text illustrate the application of the experimental methods such as micro moire technique, speckle pattern photography or X-ray stress analysis in connection with numerical simulations. Finally, actual results concerning solder joint reliability are discussed.<>
