A Ceramic PCB uses aceramic substrate instead of conventional FR-4 material. Common substratematerials include alumina (Al₂O₃) and aluminum nitride (AlN).
Ceramic circuit boardscombine high thermal conductivity, electrical insulation and dimensionalstability. They are suitable for electronic systems that operate under highpower, high temperature or demanding environmental conditions.
Ceramic PCBs supportelectronic components while efficiently transferring heat away from powerdevices.
Depending on thedesign, they can provide:
Efficient heat dissipation
Electrical insulation
High-power circuit support
Stable operation at elevated temperatures
Power and signal transmission
High-frequency circuit support
Improved thermal reliability
Compact electronic-module integration

Ceramic PCBs can becustomized according to project requirements, including:
Alumina (Al₂O₃) substrates
Aluminum nitride (AlN) substrates
Single-sided and double-sided circuits
Different ceramic and copper thicknesses
DBC, DPC and thick-film processes
High-current copper designs
Fine-line circuit patterns
Custom shapes and dimensions
Prototype and volume production
Component assembly support
Reliable Ceramic PCBproduction requires careful attention to:
Ceramic material selection
Required thermal conductivity
Copper and substrate thickness
Electrical insulation
Current and voltage requirements
Component heat generation
Coefficient of thermal expansion
Mechanical mounting and stress
Surface finish and bonding method
Operating temperature and environment
Because ceramicmaterials are hard but relatively brittle, mechanical dimensions and mountingmethods should be confirmed before production.
