A hybrid optimization approach for chip placement of multi-chip module packaging

The aim of this article is to provide a systematic method to perform optimization design for chip placement of multi-chip module in electronic packaging. Based on the investigation of the structural and thermal characteristics of multi-chip module, the key performance indexes of multi-chip module that include the lowest internal temperature objective, thermal-transfer accuracy, chip placement are analyzed. A hybrid model is presented by using genetic algorithm and response surface methodology for optimization. Furthermore, some design processes for improving the performance are induced. Finally, an example is discussed to apply the method.
