摘　　要：金刚石/铜复合材料由于具有热导率高、热膨胀系数低等优异的特性,已经逐步替代传统的散热材料,成为新一代电子封装材料。近年来,价格不断下降的人造金刚石和铜这种相对价格低廉的金属结合,实现人们对电子封装材料性能优越、成本可控的要求。介绍了金刚石/铜复合材料的主要制备方法以及如何改善与提高这类材料的热导率。然而,对于当前工业化的迅猛发展以及5G时代的到来,如何实现高热导率的金刚石/铜复合材料的大规模工业生产,仍然是一个挑战。Diamond/copper composites have gradually replaced the traditional heat dissipation materials and become a new generation of electronic packaging materials due to their high thermal conductivity,low thermal expansion coefficient and other excellent characteristics.In recent years,the combination of inexpensive artificial diamond and copper has realized the control of performance and cost of electronic packaging materials.This paper mainly introduces the main preparation methods of diamond/copper composites and how to improve and enhance the thermal conductivity of diamond/copper composites.However,for the current rapid development of industrialization and the advent of the 5G era,how to achieve large-scale industrial production of diamond/copper composites with high thermal conductivity is still a challenge.
