Nitride Application

The mainstream application market is in high-power LEDs, power modules, and laser fields. Aluminum nitride is also a mainstream ceramic circuit board substrate relative to alumina. But currently only high-power LEDs, such as stagelights, lights, projectiles, and Uvled will only be used in aluminum nitride. Alternatively the semiconductor laser and the DC-DC power module.
One is that the heat management needs of these products are relatively high, and high-conducting substrates require high thermal conductivity to help them heat, and the other is that these product chip materials are silicon, chip and aluminum nitride ceramics. The coefficient of thermal expansion is closer, and the two are combined in thermal deformation. In the middle, it will not be able to use the chip better. In the future, the application of aluminum nitride will be more and more, the product is smaller, the functions are getting stronger, and the requirements for this substrate will be higher and higher. High thermal conductivity is a topic that is always invasive, aluminum nitride is currently the most cost-effective substrate.
