 |
The Aluminium Nitride product is a new material having such characteristics as superior thermal conductivity, high electric insulation, and coefficient of thermal expansion similar to that of silicon (Si) and is drawing attention as a next-generation material with high thermal conductivity.
■Features
|
• |
Thermal conductivity |
:High thermal conductivity about 7 times that of Alumina. |
|
• |
Coefficient of thermal expansion |
:Having coefficient of thermal expansion similar to that of silicon, it realizes a high reliability against installation of a large Si chip and heat cycle. |
|
• |
Electrical characteristic |
:High electric insulation, and low dielectric constant. |
|
• |
Mechanical characteristics |
:Mechanical strength higher than that of Alumina. |
|
• |
Corrosion resistance |
:Superior corrosion resistance against molten metal. |
|
• |
Purity |
:Very small content of impurities, no toxicity, high purity. |
