Introduction to High Quality 96% Aluminum Oxide PCB Substrate Al2O3 Ceramic Board

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of High Quality 96% Aluminum Oxide PCB Substrate Al2O3 Ceramic Board

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.

Specifications of High Quality 96% Aluminum Oxide PCB Substrate Al2O3 Ceramic Board

High quality 96% Aluminum Oxide (Al2O3) ceramic boards form excellent PCB substrates. This material is mostly pure aluminum oxide. It delivers strong performance for demanding electronics. The key benefit is outstanding thermal conductivity. Heat moves fast through this board. Typical values range from 24 to 28 W/mK. This keeps components cool. It prevents overheating. This is vital for power electronics and LED systems.

Electrical insulation is another major strength. The dielectric strength is very high. It stops electricity leaking between parts. This ensures safe operation at high voltages. The dielectric constant is stable. It stays consistent across frequencies. Signal integrity remains high. This is crucial for RF and microwave circuits.

Mechanical properties matter too. These ceramic boards are very hard. They resist scratches and wear well. They are also quite stiff. The material doesn’t bend easily. This provides solid support for components. It handles thermal stress reliably. Boards don’t crack easily during temperature changes. Think circuit boards for powerful lasers or car electronics.

The boards are dimensionally stable. Size changes little with heat. This is important for precision assemblies. Tolerances stay tight during use. Surface finish is smooth and flat. This is necessary for accurate circuit printing. Fine lines and spaces are achievable. The boards are chemically inert. They resist most acids and solvents. This ensures long-term reliability in harsh conditions. Surface roughness is carefully controlled. It promotes good adhesion for metallization layers. This creates strong, reliable electrical connections. The alumina surface is ready for precise circuit fabrication.

Applications of High Quality 96% Aluminum Oxide PCB Substrate Al2O3 Ceramic Board

This Al2O3 ceramic board uses 96% pure aluminum oxide. It’s a top choice for demanding printed circuit boards needing serious performance. The material itself is very hard and strong. It handles high heat extremely well. This means your PCB won’t warp or crack easily under tough conditions. Heat moves through it quickly too. This keeps hot components cooler, making your whole device more reliable for longer.

Electrical insulation is another major benefit. Alumina stops electricity leaking where it shouldn’t. This is critical for circuits working with high power or high voltages. Safety and preventing short circuits depend on this. The board also resists chemical damage well. It won’t break down easily from acids, bases, or other harsh stuff. This adds to its long life.

Its stable size is important for precision. The board doesn’t expand or shrink much when temperatures change. Components soldered onto it stay firmly in place. This avoids connection failures. The smooth surface is perfect for applying fine circuit patterns. Manufacturers get clean, accurate copper traces every time. This leads to fewer defects and better yields.

You see these boards in places where regular materials fail. High-power LED lights use them to manage intense heat. Power supplies and converters rely on their insulation and strength. Hybrid and electric vehicle systems need their toughness. RF and microwave equipment uses them for stable signals. Industrial heaters and sensors benefit from their heat tolerance. Aerospace and defense applications demand this level of reliability. Medical devices trust it for critical electronics. Essentially, any circuit facing extreme heat, power, or needing rock-solid stability is a candidate for this alumina substrate.
