Ceramic Thermal Substrates & Metal Core PCB

Ceramic thermal substrates claim a higher thermal conductivity than other components in metal core circuits.

Many mainstream applications have begun to use ceramics including solar equipment, LED televisions, smart mobile phones and automotive components.

These ceramic substrates are one of either thick or thin film. Thick is mostly used in the automotive and military fields for high heat generating equipment, while the latter is used mostly for powerful LEDs.

The main materials of these 2 kinds of ceramic thermal substrates are AlN, Alumina and Al₂O₃.
