Aluminum Nitride Substrates

Aluminum Nitride (AlN) substrates are high-performance ceramic materials known for their exceptional thermal conductivity, excellent electrical insulation, and outstanding mechanical properties. These substrates are widely used in electronic, semiconductor, and high-power applications where efficient heat dissipation and electrical isolation are crucial.

Key Features:

• Superior Thermal Conductivity – AlN substrates offer thermal conductivity up to 180 W/m·K, significantly enhancing heat dissipation in high-power electronics.
• Excellent Electrical Insulation – With high electrical resistivity, AlN provides outstanding insulation properties, making it ideal for microelectronics and power modules.
• High Mechanical Strength – Strong and durable, AlN substrates can withstand mechanical and thermal stresses without compromising performance.
• High-Temperature Stability – These substrates maintain structural integrity at elevated temperatures, making them suitable for extreme working conditions.
• Low Thermal Expansion – The thermal expansion coefficient of AlN is close to that of silicon, ensuring compatibility with semiconductor materials and reducing thermal stress.
• Chemical Resistance – AlN is resistant to most acids and alkalis, ensuring long-term stability in harsh environments.
