CVD Diamond Pates and Domes

CVD Diamond has been recognized an ideal material for various applications because of its outstanding properties which includes extreme hardness and strength, high thermal conductivity, low thermal expansion, excellent dielectric properties, resistance to chemical attack, and optical transmission over a wide spectral range. It can be widely used in complex tooling and machining processes, thermal-management applications, semiconductor industry and microwave engineering.
Thermal-Management Solutions
Polycrystalline CVD diamond is suitable for a variety of high-performance temperature-management applications. Specifications for thermal conductivity range up to 2000 W/m-K. At present, CVD diamond is used as mounts for high-power integrated circuits, laser diodes, GaN on Diamond (GOD) and heat spreaders for satellite based electronic systems.
