Alumina substrate has the characteristics of high insulation, high thermal conductivity, high density and low dielectric loss.
Used in chip resistor, heat sink, integrated circuit board, potentiometer and other fields.
Advantages of alumina substrate:
1. The strength is higher than clay ceramics, the hardness is high, and the wear resistance is good.
2. High temperature resistance, can be used for a long time at 1600 degrees.
3. Strong corrosion resistance.
4. Good electrical insulation performance, especially at high temperatures, can withstand more than 8000 volts per millimeter thickness.
Alumina ceramic Substrate Application:
Used in chip resistor, heat sink, integrated circuit board, potentiometer and other fields.
