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 Double Sided Polished Aluminium Nitride Ceramic Plate ALN Sheet For LED

What makes aluminium nitride ceramic plates good for LED use?
Aluminium nitride ceramic plates handle heat well. LEDs create heat during operation. These plates move heat away from the LED chips fast. This keeps LEDs cooler. Cooler LEDs last longer and work better. The material also stops electricity from passing through. This protects LED parts from damage.

How does aluminium nitride compare to alumina or aluminum in thermal performance?
Aluminium nitride moves heat better than alumina or aluminum. Alumina transfers about 30 W/mK. Aluminum nitride transfers 150-180 W/mK. More heat moves away quickly. This makes it better for high-power LEDs. It also expands less when heated. This reduces stress on connected parts.

What temperatures can aluminium nitride ceramic plates handle?
These plates work in temperatures up to 1,400°C. They stay stable in very hot or cold conditions. LEDs often run hot. The plates won’t warp or crack. This reliability suits industrial or outdoor LED setups.

Why is double-sided polishing important for these plates?
Smooth surfaces matter for attaching LED parts. Double polishing removes tiny flaws. Flaws can trap heat or cause gaps. A flat surface ensures tight contact with chips or cooling parts. Better contact means better heat flow.

Where are aluminium nitride plates commonly used in LED systems?
They’re used in LED packaging, chip substrates, and heat sinks. High-power LEDs in streetlights, car headlights, or stage lighting need them. Any LED setup requiring fast heat removal uses these plates. They help prevent overheating failures.
