Abstract:Diamond/aluminum composites, the fourth generation of electronic packaging materials, have attracted much attention for their remarkable comprehensive properties, such as high thermal conductivity, low coefficient of thermal expansion and low density. The research situation in diamond/aluminum composites was surveyed, and the advantages and disadvantages of the preparation processes that include squeeze casting, infiltration and spark plasma sintering were analyzed. Factors related to thermophysical properties, such us thermal conductivity and coefficient of thermal expansion were discussed. Finally, the relevant problems and development tendency were also addressed.
Key words: electronic packaging; diamond/aluminum composites; thermal conductivity; thermal expansion coefficient
