NR0916 Aluminum Nitride Substrates, AlN Substrates
Description
Advanced Ceramic Materials (ACM) offers high-purity Aluminum Nitride (AlN) Substrates, a superior ceramic material known for its excellent thermal conductivity, high electrical insulation, and low thermal expansion. AlN substrates are widely used in the microelectronics industry due to their ability to withstand high temperatures and their superior mechanical properties. The protective aluminum oxide layer that forms on the surface enhances durability, allowing use up to 1370°C.
Key Features and Benefits
- High Thermal Conductivity: Greater than 170 W/mK, ideal for heat dissipation.
- High Electrical Insulation: Superior dielectric strength, >1.10^12Ωcm.
- Mechanical Strength: Biaxial strength >320 MPa ensures durability.
- Low Thermal Expansion: Coefficient of 4 to 6 x 10^-6/K between 20 and 1000°C.
- Good Metallization Capacity: Suitable for various electronics applications.
- Non-Toxic: Safe alternative to BeO.
