Process for Fabricating Composite Material Having High Thermal Conductivity
U.S. Patent 6,264,882 B1
July 24, 2001
A process for fabricating a composite material with high thermal conductivity for specific applications, for example, as a heat sink or heat spreader for high-density integrated circuits. The composite material produced by this process has a thermal conductivity between that of diamond and copper and basically consists of coated diamond particles dispersed in a high-conductivity metal, such as copper. The composite material can be fabricated in small or relatively large sizes using inexpensive materials. The process consists, for example, of sputter-coating diamond powder with several elements—including a carbide-forming element and a brazeable material—compacting them into a porous body, and infiltrating the porous body with a suitable braze material, such as a copper–silver alloy, thereby producing a dense diamond–copper composite material with a thermal conductivity comparable to synthetic diamond films at a fraction of the cost.


HER DAMIT!!!

weiß man auch wieviel das zeugs kostet?

naja dann wirds wohl noch länger dauern, bis man es sich kaufen kann.

außerdem glaub ich net, dass sich das material ein "normalsterblicher" kaufen werden kann.

hab diese firma in boston, ma gefunden, die dieses material herstellt...mit besserer waermeleitfaehigkeit als der 'skeleton cemented diamond'....und 'low cost' was immer das heissen mag ;-)

mal schaun, obs davon auch was gratis gibt ;-)

diamond-copper im vergleich zu ScD

ist das micht die gleiche tabelle die jugger in seinem thrad gepostet hat - hat er so eine platte?

jap, genau die hat er gepostet, sein diamantkühler
