CVD Diamond Heat Sink Thermal

Industrial synthetic diamond film -- application on thermal heat sink

Chemical Vapor Deposition (CVD) diamond film is made by Chemical Vapor Deposition process. The thermal conductivity of the diamond at room temperature can be up to 22 W/(cm·k), which is 5 times of the thermal conductivity of copper, 6 times of the thermal conductivity of aluminum nitride, and more than 7 times of the beryllium oxide. It can transmit heat generated by electronic devices. Furthermore, the diamond is a typical insulator due to its resistivity is as high as 1016 Ω. Therefore, the diamond is the most ideal material for thermal sink. It mainly applies to the array of high-power diode, high-power light emitting diode (LED), radio frequency power transistor, high-power & high-frequency electronic (optoelectronic) devices, the cooling fin of multichip module large-scale integrated circuit, packaging of semiconductor, etc. The cooling capacity of integrated chip of laser equipment can be enhanced by 30% to 100% with CVD diamond cooling fin.
