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 Aln Aluminium Nitride Ceramic Substrate Chip Shim for Power Modules

1. What is the Aluminium Nitride Ceramic Substrate Chip Shim made of? The chip shim is made from aluminium nitride ceramic. This material is synthetic. It combines aluminium and nitrogen atoms under high heat. The process creates a dense, stable structure. Aluminium nitride has no added binders or impurities. This ensures high purity for reliable performance.

2. Why choose aluminium nitride over other materials? Aluminium nitride conducts heat better than most ceramics. It moves heat away from power modules fast. It also blocks electricity completely. This prevents short circuits. It handles extreme temperatures without cracking. Other materials like alumina or metals may not last as long under stress.

3. How does the chip shim improve heat management in power modules? Power modules generate heat during operation. The chip shim sits between the heat source and the cooling system. It transfers heat quickly to the heatsink or casing. This keeps temperatures stable. Overheating damages components. The shim reduces this risk.

4. Where is the AlN ceramic substrate commonly used? It is used in high-power electronics. Examples include electric vehicles, industrial motor drives, and renewable energy systems. Devices like IGBT modules and LED arrays rely on it. Any application needing heat control and electrical insulation can benefit.
