Overview of Black Color Aluminum Nitride Ceramic 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 Black Color Aluminum Nitride Ceramic 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 Black Color Aluminum Nitride Ceramic Substrate

Black aluminum nitride ceramic substrate handles heat well. People often have questions about it. Here are five common ones.

What is black aluminum nitride ceramic substrate? It’s a special material made mostly from aluminum nitride powder. Manufacturers add a small amount of pigment, usually carbon black. This makes the ceramic black. The base material is very good at moving heat away.

Why is it black? Producers add a colorant, typically carbon black particles, during the mixing stage. This happens before the powder gets pressed and fired. The carbon black evenly spreads through the material. This gives the final ceramic its dark color.

Is black AlN better at conducting heat than white AlN? Usually, yes. The carbon black helps heat move through the material more easily. Think of the carbon particles creating extra paths for the heat to travel. This gives black AlN higher thermal conductivity compared to standard white AlN. It moves heat faster.

Where is black aluminum nitride ceramic substrate used? It goes into places needing top heat management. You find it in high-power LED lights. It works in RF devices and microwave packages. It’s common in semiconductor laser packages too. Any device generating lots of heat benefits from this substrate.

How does black AlN compare to white AlN? The main difference is thermal performance. Black AlN typically moves heat better. This is because of the carbon black additive. Both types offer excellent electrical insulation. Both resist chemical damage well. Black AlN might cost slightly more. This depends on the specific grade and supplier. The color choice depends on the exact heat needs.
