Aluminum nitride ceramic substrate

Properties of Aluminum Nitride Ceramic Substrate

 

1. With high thermal conductivity, up to 220W/(℃*m), small thermal expansion coefficient, only around 4*10-6/℃, thermal shock resistance is good.

 

 

2. Good electric insulation, high breakdown voltage, large current carrying capacity.

 

 

3. High mechanical strength, good toughness, strong resistance to mechanical impact.

 

 

4. It can resist erosion of various acid, alkali and other chemical substances, corrosion resistance is very good.

 

 

5. Low dielectric constant and dielectric loss can reduce the energy loss during signal transmission.
