Polycrystalline Diamond

Polycrystalline Diamond Heat Spreader is a high thermal conductivity heat dissipation substrate prepared by CVD chemical vapor deposition process, densely grown with a large number of nano/micron-scale diamond grains. Compared with single crystal diamond, polycrystalline diamond features customizable large size, high cost performance, uniform internal stress and excellent crack resistance. It is a mainstream heat dissipation and insulating material for high-power industrial devices, optoelectronic equipment and power modules.
