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 Electrical Insulation Aluminum Nitride AlN Ceramic Substrate With Surface Polishing

What is Aluminum Nitride (AlN) ceramic substrate? Aluminum Nitride ceramic substrate is a material used in electronics for insulation and heat management. It is made from aluminum and nitrogen atoms bonded tightly. This structure gives it high thermal conductivity and electrical insulation. It works well in high-power applications where heat must move away quickly.

Why use Aluminum Nitride for electrical insulation? Aluminum Nitride does not conduct electricity but moves heat efficiently. This makes it better than materials like alumina. Alumina has lower thermal conductivity. AlN keeps devices cool while preventing electrical leaks. This is critical in circuits and power systems where overheating or short circuits cause failures.

What does surface polishing do for AlN substrates? Polishing makes the substrate surface smooth. Rough surfaces trap heat or interfere with circuit layers. A polished surface improves heat transfer and reduces defects. It also helps bond metal layers more evenly. This step ensures better performance in high-precision applications like LEDs or microchips.

Where are polished AlN substrates commonly used? They are used in power electronics, LED lighting, and semiconductor devices. High-power modules need materials that handle heat and electricity safely. Polished AlN substrates fit in laser diodes, radio-frequency systems, and automotive electronics. They suit environments demanding reliability and efficient thermal management.

How should AlN substrates be handled and stored? Handle them carefully to avoid chipping or cracking. Use gloves to prevent oil or dirt from affecting performance. Store in dry conditions to stop moisture absorption. Clean with mild solvents if needed. Follow manufacturer guidelines for temperature limits during installation or use. Proper care extends lifespan and maintains insulation properties.
