TKD company supplies CVD diamond for polycrystalline and single crystal materials with consistent and repeatable properties. The manufacturing process is strictly controlled to synthesis materials tailored to the needs of a particular application.
Size availability:
Max diameter: D66 and D60 mm.
Rough Thickness range: 0.25mm-1.8mm
Polished thickness: Between 0.2-1.0mm
Polishing precision: 》15 nm
Polishingside：Nucleation and growing surfaces both.
Processing way to achieve different size and shape: High precision Laser cutting method.
CVD diamond properties:
Fully dense with high purity diamond.
High abrasion resistance and low thermal expansion coefficient
Good electrical conductivity.
Application:
CVD polycrystalline diamond is used as submount film(heat spreader，heat sinker) for high-power electronic and optoelectronic devices, such as high-power couplers, high-power integrated circuits, microwave diodes and laser diodes etc.
Standard Sizesas per above mentioned.
For Large size needed, we offer two types below:
1, Economic type: Few cracks or chips are allowed on the surface of CVD wafer/film.
2, Premium type: No any crack is allowed on the surface of CVD wafer/film.
Before you make inquiry, please do make specific drawing and requirement for our reference.
