Advantages of Ceramic PCB
High Thermal Conductivity
AIN up to 320 W/m·k — over 100× FR-4, for fast heat spreading.
Survives rapid heating/cooling without cracking or delamination.
High dielectric strength safely isolates high-voltage circuits.
Expansion close to silicon, protecting bare-die solder joints.
Copper up to 800µm for high current in a compact footprint.
Halogen-free, lead-free, RoHS/REACH compliant, no outgassing.

High Power LED Lighting
Ceramic substrates with thermal conductivity up to 320 W/m·k draw heat straight from the LED junction to the board, boosting lumen output and extending service life. Ideal for street lighting, automotive headlamps and grow lights.
Unlike FR-4 or MCPCB with a dielectric layer, ceramic lets the chip bond directly to the substrate for uniform temperature and no delamination. Lower junction temperature means higher efficacy and longer rated life.
Laser Machine
Ceramic PCBs endure the high power density and thermal shock of laser diodes, while a CTE close to silicon protects sensitive optics. Widely used in industrial laser cutting/welding, medical lasers and LiDAR.
The substrate’s dielectric isolation allows high-current drive paths and optical components to share one compact board, with stable performance at the high frequencies laser drivers demand.
Medical Equipment
High insulation, high-frequency stability and proven reliability make ceramic boards safe for life-critical devices. Applied in implantable sensors, endoscopes, imaging and RF ablation systems.
Packages are biocompatibility-friendly and sterilizable, with a small form factor for minimally invasive tools, meeting the strict qualification medical programs require.
Aerospace & Aviation
Withstanding extreme temperature swings and radiation while staying lightweight, ceramic PCBs perform where FR-4 fails. Used in avionics, satellite systems, radar and airborne sensor arrays.
Ceramic is outgassing-free and vibration resistant, with hermetic-friendly construction that survives long missions without material degradation.
Solar Energy
Excellent high-voltage insulation and long-term outdoor stability support reliable thermal management in power conversion. Found in PV inverters, MPPT controllers and concentrator photovoltaic modules.
Ceramic resists daily thermal cycling and humidity, shrinks the required heatsink and raises conversion efficiency across the system’s service life.

Frequently Asked Questions
What is ceramic PCB?
A ceramic PCB (ceramic printed circuit board) uses a ceramic material — such as alumina (Al₂O₃), aluminum nitride (AIN), silicon nitride (Si₃N₄), beryllium oxide (BeO), boron nitride (BN), silicon carbide (SiC) or zirconia (ZrO₂) — as the substrate instead of standard FR-4. Ceramic substrates provide far higher thermal conductivity and electrical insulation, making them ideal for high-temperature, high-power and high-frequency applications where ordinary boards would fail.
Could you make 4 layer ceramic PCB
Yes. Andwin manufactures ceramic PCBs from 1 to 12 layers. A 4-layer ceramic board is well within our standard capability, and we can also build multilayer stacks with blind and buried vias on request.
What is the use of ceramic PCB?
Ceramic PCBs are widely used in high-power LED lighting, laser equipment, medical devices, aerospace and aviation, solar energy, power electronics, electric vehicles (EV), 5G / telecom and industrial control — anywhere that demands excellent heat dissipation, insulation and long-term reliability.
What is the temperature ceramic PCB can work at?
Ceramic PCBs operate reliably at high temperatures, with typical continuous service up to 350℃. Certain ceramic materials such as AIN and SiC can withstand even higher thermal loads thanks to their low thermal expansion and high stability.
Why choose ceramic PCB?
Ceramic PCBs are chosen because they deliver excellent thermal conductivity up to 320 W/m·k for AIN, far above FR-4, with superior thermal cycling resistance that avoids cracking under rapid heating, high electrical insulation for safe high-voltage operation, a thermal expansion coefficient close to silicon that protects bare chips, high current carrying capacity in a compact footprint, eco-friendly halogen-free and lead-free construction, stable electrical performance at high frequency, long service life with high reliability, and the ability to miniaturize power modules and packages.
How to choose ceramic PCB manufacturer?
When choosing a ceramic PCB manufacturer, verify their years of experience and proven track record, check material capabilities across Al₂O₃, AIN, Si₃N₄, BeO, BN, SiC and ZrO₂, confirm process coverage of DPC, DBC, Thick film and AMB, review certifications such as ISO 9001, IATF 16949, UL and RoHS, ask about minimum line width and spacing down to 25/25µm, evaluate prototyping and quick-turn ability, confirm supported layer count and copper-thickness range, check that testing includes 100% E-Test, DRC and FQC visual inspection, and finally compare lead time, MOQ and pre-sales / after-sales support.
What is ceramic PCB manufacturing process?
There are four main processes — DPC (Direct Plated Copper), DBC (Direct Bonded Copper), Thick Film and AMB (Active Metal Brazing) — and the DPC flow consists of ten steps performed in sequence: laser drilling, screen printing, firing or baking, sputtering to deposit the seed layer, electroplating to build up copper, exposure, etching, resist stripping, surface finishing with ENIG, ENIPIG, Immersion Silver or OSP, and finally AOI with FQC final inspection.
