Aluminium Nitride Ceramic substrate
Basic characteristics:
- High thermal conductivity (170-230W/mK), up to 9.5 times than that of Alumina
- Similar coefficient of thermal expansion to that of silicon (Si).
- Higher electric insulation, and Smaller dielectric constant
- Higher mechanical strength (450MPa)
- Superior corrosion resistance against molten metal.
- Very high purity, no toxicity.
