Features
- Ultra-high thermal conductivity: Diamond materials have very high thermal conductivity, up to
2000-2500 W/m·K. Compared with ordinary copper plate, the thermal
conductivity of diamond copper-clad plate can be 10-20 times
higher. This gives it a unique advantage in applications such as
heat dissipation of high-power electronic devices.
- Excellent electrical conductivity: By combining the diamond thermal interface layer with the copper
substrate, excellent electrical conductivity can be achieved to
meet the requirements of electronic equipment for high electrical
conductivity.
- Low coefficient of thermal expansion: the coefficient of thermal expansion of diamond is about
1.1×10^-6/°C, much lower than the 17×10^-6/°C of copper. This is
beneficial to reduce the material stress and deformation caused by
thermal expansion, and improve the reliability of the device.
- High mechanical strength: Diamond materials have ultra-high hardness and compressive
strength, which can improve the overall mechanical strength of
composite materials. This is important for some electronic devices
that are subjected to greater mechanical stress.
- Good insulation: Diamond itself is an excellent insulator and can provide excellent
insulation properties in composite materials. This is very helpful
for the insulation and isolation of electronic devices.
- Excellent chemical stability: Diamond is chemically very stable and can improve the corrosion
resistance of composite materials in a variety of harsh
environments.
