Advantages of Aluminum Nitride Ceramic PCBs

Aluminum Nitride (AlN): High thermal conductivity and a thermal expansion coefficient close to that of silicon, making it suitable for high-speed lasers and power modules.

Advantages：

• High thermal conductivity: Aluminum nitride has a thermal conductivity significantly higher than aluminum oxide, approximately five times higher, allowing heat to dissipate quickly from electronic components.

• High electrical resistance: Aluminum nitride also has good electrical resistance.
  
• Coefficient of thermal expansion close to that of silicon: Aluminum nitride has a thermal expansion coefficient similar to that of semiconductor silicon, making it less likely for chips to fall off the substrate when used in high-power devices.
  
• High mechanical strength: Aluminum nitride has excellent mechanical properties, providing good flexural strength and impact resistance.
  
  
  

Aluminum nitride ceramic PCBs are widely used in high-power electronic components and large-scale integrated circuits due to their excellent thermal conductivity and good compatibility with semiconductors.
