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 Aluminium Nitride Aln Ceramic Substrate Sheet for Electronic

What is aluminium nitride ceramic substrate sheet used for?
Aluminium nitride ceramic substrate sheets are mainly used in electronic devices needing high thermal conductivity. They help transfer heat away from components like power semiconductors, LED chips, and radio frequency modules. This prevents overheating and improves device reliability.

How does aluminium nitride compare to alumina ceramics?
Aluminium nitride conducts heat much better than alumina. Alumina has around 20-30 W/mK thermal conductivity. Aluminium nitride offers 150-180 W/mK. This makes aluminium nitride better for high-power applications where heat buildup is a problem.

Can aluminium nitride substrates handle high temperatures?
Yes. Aluminium nitride substrates work well in temperatures up to 1000°C. They stay stable under extreme heat without cracking or warping. This makes them suitable for harsh environments like aerospace or automotive electronics.

Why pick aluminium nitride over beryllia ceramics?
Aluminium nitride is safer. Beryllia is toxic if inhaled as dust. Aluminium nitride provides similar thermal performance without health risks. It also resists corrosion better in humid or chemically active settings.

How should aluminium nitride substrates be stored?
Store them in dry, room-temperature conditions. Moisture can cause surface reactions over time. Handle with clean gloves to avoid oil or dirt contamination. Use non-abrasive cleaning methods if needed.
