Abstract:The metal matrix composites(MMCs) is one of the important directions on the research of electronic packaging due to their excellent properties and increasingly mature manufacturing methods. The progress in the research on typical MMCs for electronic packaging was reviewed. The thermo-physical properties design, the key factors controlling the thermo-physical properties of Al-matrix and Cu-matrix composites, the improvement measures and the common manufacturing methods were discussed. The prospects for the future development of MMCs for electronic packaging were given at the end.
Key words: electronic packaging; metal matrix composites; thermal conductivity; thermal expansion coefficient
