Description

Diamond has thermal conductivity five times that of copper and is an electrical insulator, making for a perfect heat sink. CVD Diamond has all of the properties of single crystal diamond without many of the size and shape limitations.

Use the ultra-high thermal conductivity of diamond for temperature critical packages. Higher power in smaller devices and the integration of these to other devices present heat dissipation challenges. High thermal heat flux significantly impacts performance and reliability. The unsurpassed thermal conductivity of diamond and its high electrical resistivity, allows for increased microprocessor frequency, higher output power, smaller parts and longer lifetimes.

Features
The maximum thermal conductivity of single crystal diamond can reach 2000 W/(mK)
Electrically insulating and good mechanical strength
Low weight, toxicity and dielectric constant
Available as a polycrystalline CVD diamond material
