Diamond-copper composites show promise for AI server cooling

A recent report from CITIC Securities highlights the potential of diamond-copper composite materials in high-performance electronics and AI servers due to their superior thermal conductivity and low thermal expansion. The report suggests that these composite materials are poised for rapid adoption in the short term for applications like encapsulation covers and cooling plates, offering a cost-effective alternative to pure diamond. In the medium term, diamond heat sinks are expected to mature for chip integration, while long-term advancements focus on single-crystal diamond wafer bonding for direct chip base integration, though challenges in size and cost remain.
