Aluminum nitride substrate – AlN


Aluminum Nitride (AlN) is the best available thermally conductive material (170 W/mK) that is also a strong electric insulator. It is therefore used in a variety of applications where heat needs to be transferred away from a component. Furthermore, it has a low coefficient of thermal expansions resulting in a CTE match with other materials like silicon and other ceramics. These characteristics make AlN a perfect material for packages and submounts of power components like power LEDs, high powers IC, high voltage inductors,…
