Highleap PCB Factory (HILPCB) specializes in manufacturing high-performance ceramic circuit boards that excel in extreme thermal, electrical, and mechanical environments. Our advanced ceramic PCB capabilities deliver superior thermal management, exceptional electrical insulation, and unmatched reliability for power electronics, LED lighting, RF/microwave systems, and automotive applications where traditional PCB materials fall short.
Advanced Ceramic Materials and Thermal Performance
Ceramic circuit boards utilize inorganic, non-metallic substrates that fundamentally outperform organic materials in thermal conductivity, dimensional stability, and high-temperature operation. Our ceramic PCB manufacturing encompasses three primary material systems:
Alumina (Al2O3) Substrates
- 96% Al2O3: Standard ceramic with 24-28 W/m·K thermal conductivity
- 99.6% Al2O3: High-purity option with superior electrical properties
- Thermal expansion coefficient: 6.5-7.5 ppm/K matching silicon devices
- Maximum operating temperature: 1500°C in inert atmosphere
Aluminum Nitride (AlN) Solutions
- Exceptional thermal conductivity: 170-230 W/m·K
- Low dielectric constant: 8.8 at 1 MHz
- Thermal expansion: 4.5 ppm/K for optimal semiconductor matching
- Ideal for high-power RF amplifiers and laser diodes
Specialized Ceramic Options
- Beryllium Oxide (BeO): 280 W/m·K thermal conductivity with handling precautions

- High-temperature bonding at 1065°C forming Cu-O eutectic
- Current carrying capacity exceeding 100A per trace
- Thermal cycling reliability: -55°C to +150°C for 1000+ cycles
Thick Film Technology
- Screen-printed conductor pastes (Ag, Au, Cu, AgPd)
- Fine line capability: 75μm traces with 75μm spacing
- Multi-layer capability with via interconnects
- Embedded resistors and capacitors for integrated passives
Thin Film Processing
- Sputtered or evaporated metallization for precision
- Line/space capability down to 10μm
- Ideal for microwave and high-frequency applications
- Compatible with wire bonding and flip-chip assembly
Our ceramic PCB facility maintains Class 1000 cleanroom environments for thin film processing, ensuring contamination-free metallization critical for high-reliability applications.

Thermal Management Solutions Using Ceramic Substrates
Ceramic circuit boards offer outstanding thermal conductivity and stability, making them ideal for applications where heat dissipation is critical to system performance and longevity. At HILPCB, we specialize in ceramic PCB solutions tailored to high-heat environments across lighting and power systems.
In high-power LED applications, our ceramic substrates enable industry-leading thermal performance. We achieve junction-to-board thermal resistance as low as 0.5 °C/W, support direct die attachment that eliminates the need for intermediate thermal interface materials, and ensure over 50,000 hours of reliable operation at junction temperatures of 150 °C. Our boards also support phosphor deposition for integrated white light generation.
For power electronics integration, we support advanced packaging needs including IGBT modules with integrated gate drivers, and high-efficiency SiC and GaN power devices. Our ceramic PCBs enable direct liquid cooling through metallized microchannel designs and deliver thermal spreading capabilities up to 10 times greater than standard FR-4 materials.
To further enhance performance, we provide thermal simulation services utilizing finite element analysis (FEA). These simulations guide design optimization of copper distribution, via placement, and component layout to maximize heat dissipation and ensure thermal reliability under demanding operating conditions.

FAQ
What are the main advantages of ceramic circuit boards over traditional PCBs?
Ceramic circuit boards offer 10-100x better thermal conductivity than FR-4, enabling superior heat dissipation for high-power applications. They maintain dimensional stability at extreme temperatures, exhibit zero moisture absorption, and provide excellent electrical insulation even at high frequencies. These properties make ceramics essential for power electronics, RF systems, and LED applications.
How do ceramic PCB costs compare to standard circuit boards?
Ceramic substrates typically cost 3-10x more than equivalent FR-4 boards due to specialized materials and processing. However, the total system cost often favors ceramics through elimination of heatsinks, improved reliability, and extended operating life. We provide detailed cost analysis comparing ceramic solutions with traditional approaches for your specific application.
Can ceramic circuit boards be manufactured in multilayer configurations?
Yes, we manufacture multilayer ceramic PCBs using LTCC (Low Temperature Co-fired Ceramic) technology supporting up to 20 layers. This enables complex 3D circuit integration with embedded passives, cavities, and channels. Standard alumina and AlN substrates are typically limited to single or double-sided configurations with thick film multilayer capabilities.
What design rules apply to ceramic circuit board layouts?
Ceramic PCBs require modified design rules including: minimum trace width of 100μm for thick film (10μm for thin film), via diameters starting at 100μm, and keepout zones near board edges to prevent chipping. We provide comprehensive design guidelines specific to your chosen ceramic material and metallization technology.
How quickly can you deliver ceramic circuit board prototypes?
Standard ceramic PCB prototypes ship in 7-10 business days for single/double-sided designs. Complex multilayer LTCC or custom metallization may require 15-20 days. We maintain inventory of common ceramic materials to minimize lead times and offer expedited services for urgent requirements.
What certifications do you hold for ceramic PCB manufacturing?
HILPCB maintains ISO 9001:2015 quality certification, IATF 16949 for automotive applications, and AS9100D for aerospace. Our ceramic processes comply with IPC standards adapted for ceramic substrates. We provide material traceability, RoHS compliance documentation, and custom testing certifications as required.
