Advantage:
The same is a ceramic circuit board, but there is a big difference. The thermal conductivity of aluminum oxide is about 45W/(m·K), and the thermal conductivity of aluminum nitride is close to 5 to 8 times.
It is a high temperature resistant material with good thermal shock resistance and can withstand extreme heat of 2200℃.
It has excellent corrosion resistance to molten aluminum, and aluminum nitride has the characteristics of not being corroded by molten aluminum, other molten metals and gallium arsenide.
It can be seen that aluminum nitride ceramic PCBs differ greatly in performance due to their different ceramic bases. Of course, the cost of aluminum nitride ceramic PCBs will be higher now, the production process will be more complicated, and the market price is more expensive than alumina ceramic plates. .
