Aluminum nitride plate/sheet/disc

Aluminum nitride sheets/plates/discs have a coefficient of thermal expansion similar to silicon, allowing them to adapt perfectly to electronic modules during temperature changes. Thanks to their excellent electrical insulation and dielectric properties, aluminum nitride sheets/plates/discs are ideal for large-scale integrated circuits or high-power modules. Manufactured through a high-temperature die-casting and sintering process, they are characterized by zero porosity, excellent flatness, and surface smoothness. Advanced Ceramics Hub can supply customized solutions in width, length, thickness, and surface finish to meet diverse industrial and research requirements.

Aluminum Nitride Ceramic Machining

Ceramic Machining HM

Aluminum Nitride (AlN) ceramic machining is a precise process used to fabricate high-performance components from aluminum nitride materials. Machining aluminum nitride ceramics requires specialized equipment and techniques to handle their brittleness and hardness. Proper tooling and controlled environments are essential to avoid material damage and achieve the desired surface finish and dimensional accuracy. The common machining methods are as follows:

  • Diamond Cutting: Diamond tools are used to achieve fine precision and smooth surface finishes, ideal for complex shapes.
  • Laser Cutting: A non-contact method used for intricate shapes, with high precision and minimal thermal impact.
  • Precision Grinding: Utilized to achieve fine tolerances and surface finishes. Requires special care to prevent cracking or chipping due to the ceramic’s brittleness.
  • Wire EDM (Electrical Discharge Machining): A method often used for intricate cutting, especially for thin and complex geometries.

Aluminum Nitride Ceramic Packaging

Aluminum Nitride Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
