Description
Advanced metal diamond composites with Silver, Aluminum and Copper matrices exhibit high thermal conductivity
in the range of 400-700 W m-1 K-1 and low CTE of about 7 – 9 ppm/K. A gas pressure assisted infiltration process
has been developed for cost-efficient industrial production of diamond composite substrates and heat sinks.
The composite microstructure and interface morphology determine the thermal properties and reliability during thermal
cycling and represent the key to advanced composite formation. An industrial scale pilot production has been installed
and the product has reached a degree of maturity allowing the application for current and future high end thermal
management applications. The status of product development as well as thermal and mechanical properties and
results of thermal cycling tests will be reviewed.
