What is a Ceramic PCB? A Ceramic PCB is a printed circuit board built using ceramic substrates like alumina (Al₂O₃), aluminum nitride (AlN), or silicon nitride (Si₃N₄) instead of standard FR-4 or PTFE materials. These substrates are thermally conductive, electrically insulating, and mechanically robust, making them ideal for high-power electronics and RF/microwave applications. Ceramic PCBs...
