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 0.5/ 0.635/ 0.1mm Thickness ALN Ceramic Plate Alumina Nitride Ceramic Substrate

What is the difference between 0.5mm, 0.635mm, and 0.1mm ALN ceramic plates? The thickness affects performance. Thinner plates like 0.1mm work for flexible electronics. Thicker ones like 0.5mm or 0.635mm handle high-power devices better. Choose based on heat management needs and device size.

Why use alumina nitride instead of alumina ceramic? Alumina nitride conducts heat better. It moves heat away faster in high-power setups. Alumina works for basic insulation. Alumina nitride suits advanced uses like LED lighting or semiconductor tools.

Can ALN ceramic plates handle extreme temperatures? Yes. They work from -40°C to 1200°C. They keep shape under heat. They resist thermal shock. This makes them good for aerospace or industrial heating systems.

Are these plates fragile? They are hard but can break if bent or hit. Handle them carefully during setup. Use proper mounting methods. Avoid sudden pressure changes. Thicker plates (0.5mm/0.635mm) handle stress better than 0.1mm ones.

Can custom sizes or shapes be made? Yes. Laser cutting drills precise holes or shapes. Custom sizes fit specific projects. Thickness options stay the same. This works for prototypes or specialized equipment.
