NGM has developed a thermally hyper-conductive diamond/carbon/carbon composite (DCC).  DCC is VGCF/carbon composite that is coated and partially infiltrated with a polycrystalline diamond film. This innovation leads to a composite with excellent heat spreading characteristics at the surface and high through-the-thickness thermal conductivity. At the same time, the surface is electrically insulating, and has coefficient of thermal expansion (CTE), which can be tailored to closely match that of silicon and gallium arsenide. These factors combine to make DCC the ideal substrate material for mounting of high heat dissipation electrical components. DCC promises to be an enabling technology for certain compact, high-power electronics applications. Black Icetm was selected by R&D Magazine as one of the 100 most technologically significant new products.
