Overview of Aluminum Nitride Aln Ceramic Sheet Substrate

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 Aln Ceramic Sheet Substrate

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 Aluminum Nitride Aln Ceramic Sheet Substrate

What exactly is Aluminum Nitride (AlN) ceramic?
Aluminum Nitride is a special ceramic material. It’s made from aluminum and nitrogen. Its biggest strength is moving heat away very fast. Think of it like a super highway for heat. This makes it perfect for electronics needing to stay cool.

Why would I pick AlN over other ceramics like alumina?
AlN moves heat much better than alumina. Alumina is common but slower. AlN handles heat roughly ten times faster. This speed is crucial for powerful electronics. AlN also works well with silicon chips. It matches their expansion when heated. This reduces stress and cracking.

Where do people mostly use AlN ceramic sheets?
You find them where heat builds up fast. They are ideal substrates for high-power LED lights. They work well in laser diodes. They are essential in power modules for electric cars. They serve in high-frequency communication devices. Any advanced electronics needing serious cooling use AlN.

How thick are standard AlN sheets?
Thickness varies based on the job. Common sizes are 0.25mm, 0.38mm, 0.5mm, 0.635mm, and 1.0mm. Thinner sheets cool small, powerful chips best. Thicker sheets offer more strength for larger parts. The exact thickness depends on the device design.

Is handling AlN tricky?
Yes, handle it carefully. AlN is very hard but also brittle. It can chip or crack if dropped or hit hard. Wear gloves to avoid oils from skin. Use proper tools when cutting or machining. Avoid sudden temperature shocks. Plan the process to prevent damage.
