Ceramic PCB Manufacturer — AlN & Alumina Ceramic Circuit Boards
FX PCB manufactures ceramic printed circuit boards in Shenzhen, China, for designs where FR4 cannot handle the heat, power density, or operating temperature. We produce ceramic PCBs with DPC (Direct Plate Copper) technology — the process we use for all ceramic orders — on aluminum nitride (AlN) and alumina (Al2O3) substrates, from prototypes to mass production. Send us your Gerber files and requirements, and our engineers will review them and return a quote in 1–2 working days. Get a Quote
Why Choose a Ceramic PCB?
- Heat dissipation: ceramic substrates conduct heat far better than organic laminates — AlN reaches a thermal conductivity of ≥170 W/(m·K).
- High temperature & insulation: strong electrical insulation and stable performance at high operating temperatures.
- Low high-frequency loss: low dielectric constant and low dielectric loss for RF and high-frequency designs.
- Reliability: no organic ingredients in the substrate, a coefficient of thermal expansion close to silicon, and a long service life in harsh environments.
Ceramic Materials We Work With
Aluminum Nitride (AlN)
For high-power and high-heat designs. Key properties: thermal conductivity ≥170 W/(m·K), dielectric constant 8–10 (1 MHz), dielectric strength ≥17 kV/mm, flexural strength ≥450 MPa. Our ceramic materials are imported from Germany and Fujian Huaqing, and every incoming batch is strictly checked. AlN Ceramic PCB
Alumina (Al2O3)
A cost-effective ceramic for LED, thick-film, and general high-temperature applications. Alumina Ceramic PCB
Processes
DPC is our standard for ceramic orders. We also supply thick-film ceramic PCBs and laser-cut ceramic substrates. Thick Film Ceramic PCB · DPC Ceramic PCB · Laser-Cut Ceramic

What Does a Ceramic PCB Cost?
Ceramic PCB pricing depends mainly on the substrate material (AlN costs more than Al2O3), board size and thickness, copper thickness, and quantity. Send us your files and we will quote your exact design in 1–2 working days — no obligation.
What Our Customers Say
★★★★★
Clement
“This was my first time ordering a ceramic PCB, and Nora was patient and professional with me while I was figuring everything out. I was extremely impressed by the quality of the product compared to other PCB fabs I’ve used in the past, and their pricing on aluminum nitride PCBs is excellent. The custom PCBs I received are exactly what I wanted, and came packed really well. Highly recommended!”
Applications
Ceramic PCBs are used primarily in LED lighting and other high-power, high-temperature, and high-frequency applications where thermal performance decides product life.
FAQ
What is a ceramic PCB?
A printed circuit board built on a ceramic substrate (such as AlN or Al2O3) instead of an organic laminate like FR4, chosen for heat dissipation, insulation, and high-temperature reliability.
DPC, DBC, LTCC, HTCC — which do you use?
We use DPC for all ceramic PCB orders: copper is plated directly onto the ceramic, giving high thermal conductivity and fine, smooth traces.
Can you assemble components on ceramic boards?
Yes — we offer PCB assembly alongside fabrication; send your BOM with your Gerber files for a turnkey quote.
