What Is a Ceramic PCB?
A ceramic PCB is a printed circuit board that uses ceramic material as the substrate instead of traditional FR4 or metal core material. Ceramic substrates provide excellent thermal conductivity, high insulation performance, low thermal expansion, and strong resistance to high temperature and harsh operating conditions.
Common ceramic PCB materials include:
- Alumina (Al2O3)
- Aluminum Nitride (AlN)
- Beryllium Oxide (BeO)
- Silicon Nitride (Si3N4)
- Other ceramic materials upon review
Ceramic PCBs are commonly used when conventional PCB materials cannot meet thermal, electrical, or reliability requirements.
