Thermal Conductive Ceramic
The thermal conductivity of the ceramic sheet is as high as 24W / M.K. it is resistant to high temperature and high pressure. The surface of the ceramic sheet is smooth without burr and burr. It is heated evenly and dissipates heat quickly; Simple and compact structure, small size, high strength, not easy to break, acid and alkali corrosion resistance, durable.
Features
- Superior chemical and mechanical stability.
- High hardness, high wear resistance.
- High thermal conductivity, high electrical insulation.
- Effective anti-interference (EMI), anti-static.
Applications
- IC / MOS / triode.
- Surface heat source for diode and IGBT.
- High density switching power supply.
- High frequency communication equipment.
- High frequency welding machine and other equipment.
