Overview of aluminum nitride ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of aluminum nitride ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

5 FAQs of Excellent Thermal Conductivity Aluminium Nitride AlN Ceramic Substrate

What is aluminium nitride (AlN) ceramic substrate? Aluminium nitride ceramic substrate is a material used in electronics. It moves heat very well. It works as an electrical insulator. This makes it good for managing heat in devices like LEDs or power modules. Its high thermal conductivity helps parts stay cool.

Why does thermal conductivity matter? Electronic parts get hot during use. Heat needs to move away fast. If heat stays, devices break or work poorly. AlN moves heat better than many materials. This keeps devices reliable. It stops overheating.

Where is AlN ceramic substrate used? It is common in high-power electronics. LED lighting uses it to handle heat. Power modules in cars or trains use it. Semiconductor manufacturing uses it for heat-sensitive steps. It fits where heat control is critical.

How does AlN compare to alumina? Alumina is another ceramic substrate. Alumina moves heat less effectively. AlN’s thermal conductivity is 170-200 W/mK. Alumina’s is 20-30 W/mK. AlN costs more. Alumina is cheaper for basic uses. AlN is better for high-power needs.

Are there handling tips for AlN substrates? AlN is sensitive to moisture. Store it in dry conditions. Avoid touching the surface with bare hands. Clean it before use. Oils or dirt weaken bonds with other materials. Follow guidelines for cutting or shaping. This prevents cracks or damage.
