Specification of High Reliability Aln Metallized Ceramic Plate Metalized Aluminum Nitride Substrate

This metallized aluminum nitride (AlN) ceramic plate offers high performance and reliability for demanding electronics. It uses pure aluminum nitride ceramic as the base material. AlN provides excellent thermal conductivity. Typical values range from 170 to 220 W/mK. This allows very efficient heat spreading away from hot components.

The ceramic surface undergoes a specialized metallization process. A tungsten or moly-manganese layer bonds directly to the AlN. This creates a strong, hermetic seal. The metal layer provides a solderable surface. You can attach components or heatsinks directly. Common finishes include nickel and gold plating over the base metal. This prevents oxidation and improves solderability.

Electrical insulation is a key feature. The AlN ceramic itself is an outstanding insulator. Its dielectric strength is very high. This prevents electrical leakage or short circuits. The material also has a low dielectric constant and loss. This is important for high-frequency circuits.

High reliability is built in. The plate withstands extreme temperatures. Operating range is typically -55°C to +350°C. It handles rapid temperature changes well. Thermal expansion closely matches silicon and gallium arsenide semiconductors. This minimizes stress on attached chips. The structure is mechanically strong and resists chemical attack.

These properties make it ideal for tough applications. Use it in high-power LED packages, laser diodes, and RF/microwave modules. It works well in power semiconductor modules like IGBTs. Automotive electronics and aerospace systems benefit from its stability. It serves as a substrate for circuits needing heat dissipation. It also works as a high-performance heat spreader or spacer. The plates come in various standard sizes and thicknesses. Custom dimensions and metallization patterns are available.

Applications of High Reliability Aln Metallized Ceramic Plate Metalized Aluminum Nitride Substrate

Aln metallized ceramic plates solve tough problems in electronics. They manage heat incredibly well. Aluminum nitride itself moves heat faster than almost any other ceramic. This matters most where things get seriously hot. Power electronics like IGBT modules and MOSFETs use these plates. They pull heat away from powerful chips fast. This stops overheating. It makes devices last longer and work better.

The metal coating on the plate is key. We usually use aluminum or copper. This coating lets you solder the plate directly onto metal circuit boards or heat sinks. It creates a strong bond. This bond moves heat efficiently from the chip, through the plate, and out. The plate expands at a rate close to silicon chips. This prevents cracking or breaking when things heat up and cool down during use. Reliability is critical.

RF and microwave devices need stable platforms. These AlN plates work great here too. They handle high frequencies well. Their electrical insulation is excellent. This prevents signal loss and interference. They are common in radar systems, satellite communications, and 5G base stations. Performance stays consistent.

LED lighting uses these plates heavily. High-power LEDs create intense light and lots of heat. The Aln plate carries that heat away effectively. This keeps the LED bright and extends its life. It prevents the color from shifting over time.

Lasers and laser diodes also depend on these substrates. They need precise temperature control. The AlN plate delivers that stability. Automotive electronics, especially in electric vehicles, face harsh conditions. High reliability AlN plates handle the heat and vibration. They keep critical power control systems running safely.

Medical imaging equipment uses sensitive sensors. These sensors need stable, non-interfering bases. The AlN plate provides this. Its combination of electrical insulation and heat spreading is unique. This makes it essential for demanding modern electronics where failure is not an option.

5 FAQs of High Reliability Aln Metallized Ceramic Plate Metalized Aluminum Nitride Substrate

High Reliability AlN Metallized Ceramic Plate FAQs

What makes these AlN plates “high reliability”?
These plates undergo strict testing. They meet tough industry standards. This ensures consistent performance. They handle extreme heat and power well. They resist wear over long periods. This reliability is crucial for demanding electronics.

Why use Aluminum Nitride instead of other ceramics?
Aluminum Nitride conducts heat superbly. Its thermal conductivity reaches 170 W/mK. This is much higher than alumina. It moves heat away from sensitive parts fast. This prevents overheating. It also matches silicon’s expansion rate well. This reduces stress in assemblies.

What does “metallized” mean for these substrates?
Metallization adds a metal layer onto the AlN ceramic. Common metals include MoMn/NiAu or Ti/Ni/Ag. This layer lets you solder components directly to the plate. It creates strong electrical connections. It also provides excellent heat spreading. The bond between metal and ceramic is very strong.

Where are these metallized AlN plates typically used?
They are vital in high-power, high-frequency electronics. Common uses are laser diode mounts, power modules, and RF packages. They are also found in aerospace systems and advanced sensors. Any application needing top heat management and electrical insulation uses them.

Can I get custom sizes or metal patterns?
Yes, customization is standard. Plates come in various thicknesses. Common sizes range from small chips to large plates. The metal layer can be patterned precisely. This includes circuits, pads, or specific shapes. Tell us your requirements. We make plates to fit your exact design.
