Ceramic PCB Material

ALN and Al2 O3 are environmentally-friendly substrate materials to replace BeO (Beryllium Oxide) for your RF resistors and terminations for high power applications.

The thermal conductivity also makes these ideal substrates for high heat components including LEDs.

High-purity alumina setters are ideal for quality improvement and cost reduction. Since high-purity Alumina has excellent corrosion resistance and thermal shock resistance, it is used for setters for sintering and heat treatment.

This is our preferred current Alumina material.
