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.

Specifications of Aluminum Nitride Ceramic Disc AlN Substrate

The Aluminum Nitride Ceramic Disc AlN Substratum is a high-performance product developed for innovative electronic devices and industrial applications. It uses excellent thermal conductivity, rising to 170-180 W/mK. This makes it very effective for taking care of warm in power tools, LED components, and semiconductor systems. The product maintains strong electrical insulation, with a dielectric strength exceeding 15 kV/mm. This makes certain trusted efficiency in high-voltage environments.

Light weight aluminum nitride ceramic stands up to chemical deterioration and stands up to extreme temperature levels. It operates stably in settings ranging from -40 ° C to 1200 ° C. Its thermal development coefficient very closely matches silicon, reducing tension in digital settings up. This compatibility enhances gadget longevity and dependability.

Standard disc dimensions consist of diameters from 10 mm to 150 mm and thicknesses from 0.3 mm to 10 mm. Personalized sizes are available for specialized requirements. Surface coatings range from brightened to lapped, guaranteeing smooth assimilation with finishings or circuits. The product’s hardness exceeds Hv 1200, giving resistance to put on and mechanical damage.

Aluminum nitride ceramic discs are non-toxic and RoHS-compliant. They match applications in aerospace, vehicle, and telecommunications. Usual usages consist of warmth sinks, wafer chucks, and laser diode bases. The low dielectric loss (tan δ < 0.001) makes it optimal for high-frequency circuits. Production processes use high-purity aluminum nitride powder. This guarantees very little contaminations and regular efficiency. Post-sintering treatments improve density, achieving over 99% of academic worth. The discs show very little porosity, preventing gas or moisture absorption. Accuracy machining allows limited tolerances, with size precision within ± 0.1 mm and density variations under ± 0.05 mm. Laser cutting and ultrasonic boring are offered for complicated geometries. Metallization layers (gold, silver, or copper) can be added for soldering or wire bonding. The material's thermal shock resistance avoids cracking during rapid temperature level changes. It retains architectural stability under repeated thermal cycling. This longevity minimizes maintenance requirements in harsh operating conditions. Aluminum nitride ceramic discs are packaged in anti-static materials to stop contamination. Custom packaging alternatives consist of vacuum-sealed containers for sensitive settings. Bulk orders are supported for massive manufacturing. Technical datasheets and product accreditations are given upon demand.

5 FAQs of Aluminum Nitride Ceramic Disc AlN Substrate

Aluminum nitride ceramic disc AlN substrates are used in electronics. Here are 5 FAQs.

What is aluminum nitride ceramic? Aluminum nitride (AlN) is a technical ceramic. It is made from aluminum and nitrogen. It has high thermal conductivity. It works well for managing heat in devices.

What makes AlN substrates special? They move heat better than many ceramics. AlN conducts heat 10 times faster than alumina. It also resists electricity. It stays stable in high temperatures. These features help in power electronics and LED systems.

Where are AlN discs commonly used? They fit in high-power devices. Examples include LED lighting, semiconductor modules, and laser diodes. They handle heat in electric cars and telecom equipment. Their insulation prevents electrical leaks.

How is AlN different from aluminum oxide? Both are ceramics. AlN moves heat better. Aluminum oxide costs less but works for basic uses. AlN suits high-performance needs. AlN also beats beryllium oxide in safety. Beryllium oxide is toxic.

How should AlN substrates be handled? Avoid sharp impacts. They are hard but can chip. Clean them with alcohol or mild solvents. Do not use abrasive tools. Store them dry to prevent moisture damage. Follow the manufacturer’s guidelines for machining.
