Overview of Industry Heat Sink Big Size Aln Substrate Aluminum Nitride Ceramic Plate

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 Industry Heat Sink Big Size Aln Substrate Aluminum Nitride Ceramic Plate

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 Industry Heat Sink Big Size Aln Substrate Aluminum Nitride Ceramic Plate

This big aluminum nitride ceramic plate works as a heat sink substrate. It handles high power and high heat situations. AlN material is the key. It moves heat away very fast. This keeps electronics cool and reliable. The thermal conductivity is excellent. It reaches over 170 W/mK. This beats regular alumina ceramics easily. Electrical insulation is also strong. It prevents current leaks effectively. You get stable performance even at high voltages.

The plate is made from pure aluminum nitride powder. It gets pressed and sintered at high temperatures. This creates a dense, strong ceramic. The material resists thermal shock well. It doesn’t crack easily when temperatures change fast. Chemical resistance is also good. It stands up to harsh environments. This makes it long-lasting and dependable.

Standard sizes are large. Think 100mm x 100mm, 150mm x 150mm, or bigger. Custom sizes are possible too. Thickness usually ranges from 0.5mm up to 3.0mm or more. We control thickness tightly. This ensures consistent performance. Surface finish is smooth. It provides a flat base for mounting components. Edge quality is clean. The cuts are precise. This avoids chipping or rough spots.

Its main job is spreading heat. It pulls heat away from hot spots. This heat goes to a bigger cooling system. These plates are vital in power electronics. Think IGBT modules, laser diodes, and LED arrays. They are crucial in electric vehicle systems. High-power RF devices use them too. Semiconductor manufacturing equipment relies on them. The big size covers large heat sources. It offers a solid thermal path. This improves overall device efficiency. It also extends the lifespan of sensitive electronics.

Applications of Industry Heat Sink Big Size Aln Substrate Aluminum Nitride Ceramic Plate

Industrial heat sinks need top performance. Big aluminum nitride ceramic plates deliver. These plates move heat fast. They cool powerful electronics effectively. Aluminum nitride beats other ceramics here. Heat transfers quickly through the AlN material. This stops hot spots from forming. Devices run cooler and last longer.

Electrical insulation is crucial too. These plates block electricity completely. They safely isolate high-power components. You avoid short circuits and failures. This happens even with high voltages nearby. The material stays stable under heat. It doesn’t crack or warp easily. Temperature swings cause less stress. This reliability matters for tough factories.

Big sizes are a key advantage. Large AlN plates handle big heat loads. They fit large power modules directly. Think electric vehicles and train systems. Power electronics there generate massive heat. These ceramic plates pull that heat away fast. They connect heat sources to metal sinks efficiently.

LED lighting uses them heavily. High-power LED arrays need serious cooling. Big AlN substrates spread the heat evenly. This prevents LED burnout and color shift. The lights stay bright and efficient longer. Semiconductor manufacturing needs them too. Big wafer processing tools get very hot. AlN plates manage this heat reliably.

The plates resist chemical damage well. Harsh factory environments don’t degrade them. They withstand flux and cleaning agents. This lowers maintenance costs significantly. Their strength prevents breakage during handling. Big plates stay intact during assembly. This saves money and reduces waste. Long-term stability is guaranteed. Performance doesn’t fade over years of use.

5 FAQs of Industry Heat Sink Big Size Aln Substrate Aluminum Nitride Ceramic Plate

Product FAQs: Large Size AlN Substrate Aluminum Nitride Ceramic Plates

What are the biggest sizes you offer for AlN ceramic plates?
We make large AlN ceramic plates. Our standard big sizes go up to 250mm x 250mm. We can make even larger pieces. Ask us about custom sizes beyond that. We know large sizes are needed for big power electronics.

Why choose AlN over aluminum oxide for large heat sinks?
Aluminum Nitride (AlN) conducts heat much better than aluminum oxide. AlN moves heat away from hotspots faster. This is critical for big components generating lots of heat. AlN also insulates electricity very well. It stops short circuits. Its strength helps with big, thin plates too.

Can these large AlN plates handle extreme temperatures?
Yes, absolutely. AlN ceramic performs well in high heat. It works fine up to around 1000°C. It also handles sudden temperature changes well. This is thermal shock resistance. It won’t crack easily when heated or cooled fast. This is vital for demanding industrial uses.

Is it hard to machine these big AlN plates?
Machining large AlN plates needs special care. The material is very hard. It requires diamond tools for cutting or drilling. We do precise machining before the final high-temperature firing. This ensures the size and flatness are perfect. Tell us your exact requirements early.

How do large AlN plates compare to metal core boards?
Large AlN plates are much better insulators than metal. You don’t need extra insulation layers. This simplifies the design. AlN also moves heat faster than most insulated metal substrates. This means better cooling for high-power devices. It’s lighter than many metal options too.
