Material Options: Alumina (Al₂O₃ ≥96%) with white appearance for cost-effective solutions, or Aluminum Nitride (AlN ≥96%) with
gray appearance for ultra-high thermal conductivity requirements
l Thermal Conductivity: Al₂O₃ ≥20 W/(m·K) / AlN ≥170 W/(m·K) – ensuring efficient heat dissipation for high-power stage
lighting applications
l Flexural Strength: Al₂O₃ ≥350 MPa / AlN ≥450 MPa – providing mechanical robustness for large-size panel installation
and transportation
l Volume Resistivity: Al₂O₃ ≥10¹⁴ Ω·cm / AlN ≥10¹³ Ω·cm – guaranteeing excellent electrical insulation under high-voltage
operation
l Dielectric Performance: Dielectric constant of 8-10 at 1MHz with low dielectric loss (Al₂O₃ ≤3×10⁻⁴ / AlN ≤4.5×10⁻⁴) –
ensuring signal integrity in high-frequency switching circuits
l Water Absorption: 0% – preventing moisture-related failures in humid stage environments
l Copper Metallization: DPC (Direct Plated Copper) process with customizable copper thickness for high-current carrying capacity
l Surface Finish: ENIG (Immersion Gold) for excellent solderability and oxidation resistance in long-term high-temperature operation
l Thermal Expansion Matching: Closely matched CTE (Coefficient of Thermal Expansion) with LED chips and power
components, minimizing thermal stress and solder joint fatigue
l High-Temperature Stability: Sustained performance at operating temperatures up to 800°C for Al₂O₃ and even higher for AlN,
suitable for high-intensity discharge (HID) lighting and moving head fixtures
1. High-Power Stage Lighting – Ceramic PCBs serve as the ideal substrate for high-power stage LED fixtures, moving
head lights, and follow spots, providing superior thermal management to maintain brightness stability and extend LED
lifespan during extended performances.
2. Automotive Electronics – Aluminum nitride (AlN) ceramic PCBs are ideal for electric vehicle power modules, IGBT heat
sinks, and transmission system control boards, offering excellent thermal conductivity and high-voltage insulation for
demanding automotive environments.
3. Aerospace & Defense – With high flexural strength (≥450 MPa) and extreme temperature resistance, ceramic PCBs are
used in satellite communication systems, radar modules, and avionics equipment where reliability is critical.
4. Industrial Power Electronics – Ceramic heater PCBs and high-power rigid ceramic boards are applied in industrial heating
equipment, power inverters, and welding machines, ensuring stable performance under high-temperature operation.
Our ceramic PCB manufacturing facility is equipped with advanced production lines including:
l DPC (Direct Plated Copper) process for high-precision metallization
l Thick-film printing and firing furnaces
l Laser cutting and precision drilling equipment
l Automatic optical inspection (AOI) and X-ray inspection systems
l ENIG (Electroless Nickel Immersion Gold) surface treatment line
Quality is ensured through 100% electrical testing, thermal cycling tests, and solderability tests in compliance with
IPC-TM-650 and GB/T standards.
