Specification of Black Color Aluminum Nitride Ceramic Substrate

This black aluminum nitride ceramic substrate handles heat extremely well. Its thermal conductivity reaches high levels, similar to beryllium oxide but much safer. This makes it perfect for demanding jobs where heat buildup causes problems. Think power electronics, high-brightness LEDs, or advanced laser gear. Heat moves away fast. So devices last longer and work better.

The deep black color is key. It absorbs light efficiently. This is crucial for laser applications needing precise energy control. The substrate won’t reflect light where it shouldn’t. It also looks good for visible components. The black isn’t just paint. It’s part of the ceramic material itself. So it stays put and keeps working.

It’s tough stuff. Aluminum nitride ceramic resists breaking. It handles physical stress reliably. This strength matters during manufacturing and in the final product. Things get bumped. It copes. The material also resists chemical attack. Many harsh substances won’t damage it. This ensures long-term stability.

Electrically, it’s an excellent insulator. High voltage won’t pass through it easily. This keeps circuits safe and prevents shorting. It works well with thin film and thick film circuits. Manufacturers can put fine metal lines directly onto it. Gold, silver, copper pastes bond reliably. The surface is smooth and flat. This precision is vital for tiny electronic parts.

It copes with big temperature swings. Devices heat up fast. They cool down fast. This substrate won’t crack under the strain. Its thermal expansion rate matches important semiconductors like silicon. This reduces stress in bonded assemblies. Everything stays together better. Performance stays consistent.

People use it in power modules, high-frequency circuits, LED packages needing heat spread, laser diode carriers, and sensor housings. It handles the heat. It provides electrical isolation. It gives a stable, reliable base for critical electronics. The black color adds specific optical advantages for lasers and visibility. It brings high performance where standard materials fall short.

Applications of Black Color Aluminum Nitride Ceramic Substrate

Black aluminum nitride ceramic substrates move heat incredibly well. This matters a lot for electronics that get very hot. The black color helps absorb laser energy during precision manufacturing steps. You get a strong, reliable bond. This material also stops electricity completely. It keeps different circuit parts safely apart. Heat builds up fast in high-power LED lights. Black AlN pulls that heat away efficiently. This protects the LED chips. Your lights last much longer. They also stay brighter over time.

Power electronics like IGBTs and MOSFETs generate serious heat. They need a base that moves heat out fast. Black AlN does this job very well. It stops the device from overheating. Your power systems run cooler. They become more reliable. Automotive electronics face tough conditions. Engine compartments are hot and vibrating. Black AlN handles this heat and stress. It provides a stable platform for control circuits. Electric cars need this performance.

Radio frequency and microwave devices demand precise signal control. Black AlN offers excellent electrical insulation. It minimizes signal loss at high frequencies. Your RF modules work better. Laser diode packages need exact temperature control. Black AlN’s thermal performance is key here. It keeps the laser diode stable. You get consistent light output. Semiconductor manufacturing uses many heated stages. Black AlN plates hold wafers steadily. They heat evenly during processing steps. This leads to better quality chips.

The black surface helps with visual inspection systems. Defects stand out more clearly. Production quality improves. You find problems faster. Thermal management modules use black AlN too. It moves heat from hotspots to cooling systems. Your electronics stay within safe temperature limits. This material works in demanding environments. It offers a good mix of thermal conductivity, electrical insulation, and mechanical strength. The black color adds useful benefits for production and inspection.

5 FAQs of Black Color Aluminum Nitride Ceramic Substrate

Black Aluminum Nitride Ceramic Substrate: Top 5 Questions

What is black aluminum nitride ceramic?
Black aluminum nitride ceramic is a special material. It’s made mainly from aluminum nitride powder. A sintering process gives it a dense, dark color. This ceramic handles heat very well. It works great for electronics needing heat control.

Why use black aluminum nitride?
Its biggest advantage is moving heat. Black aluminum nitride moves heat away from parts extremely fast. This prevents overheating. It also insulates electricity perfectly. The material is very strong mechanically. It resists wear and tear. It doesn’t change size much with temperature shifts.

Why is it black?
The black color isn’t paint. It comes from the manufacturing. Special additives create the dark shade during sintering. This color might help spread heat slightly better in some cases. It also looks different from regular white ceramics.

Where is black aluminum nitride used?
This material fits demanding electronics. You see it in high-power LED lights. It keeps the LEDs cool. Power modules use it. RF/microwave devices need it. High-performance computer chips rely on it. Any place generating lots of heat needs this substrate.

Is it fragile?
Handle it carefully. Like most ceramics, it can break if dropped or hit hard. It doesn’t bend like metal. Avoid sudden temperature shocks. Don’t heat or cool it too fast. Use proper mounting methods. This prevents cracks from stress.
