Thermal conductivity of ceramic circuit substrates:

Ceramic materials have good thermal conductivity. In comparison, traditional organic substrate materials have low thermal conductivity. Common ceramic circuit substrate materials, such as aluminum nitride (AlN) and silicon nitride (Si3N4), have high thermal conductivity, respectively 170-200 W/(m·K) and 80-140 W/(m·K ). This allows the ceramic circuit board to dissipate heat more effectively, improving thermal management capabilities. (INNOVACERA provides a variety of high-quality ceramic substrate materials).
