UVC Ceramic pcb™

UVC Ceramic PCB™ Technology

UVC light is becoming the standard solution for air, water, and surface sterilization because it neutralizes harmful pathogens without chemicals. Compared to traditional mercury vapor lamps, UVC LED technology provides a safer, more sustainable, and environmentally friendly alternative.

Applications include:

  • Water disinfection in residential systems, municipal water treatment, and swimming pools
  • Surface sterilization in hospitals, laboratories, and packaging facilities
  • Air purification in HVAC systems, offices, and public buildings

UVC LEDs are favored for their compact size, low energy consumption, and versatility, making them a superior choice for modern sterilization systems.

The Challenge with Conventional UVC LED PCBs

While UVC LEDs have clear advantages, they face two major limitations:

  1. Excessive heat generation that reduces efficiency
  2. Radiation damage that degrades conventional MCPCBs over time

Standard MCPCBs rely on an organic dielectric layer, which breaks down under continuous UVC exposure, shortening lifespan and performance reliability.

COFAN’s Innovative UVC Ceramic PCB™ SolutionPatented Technology Combined

The innovative UVC Ceramic PCB™️ uses patented technology like the Super Pillar and the 3-Pad Flip Chip.

Combining our Super Pillar™️ technology with the 3-Pad Flip Chip™️ from our sister company, Flip Chip Opto, we’re able to increase output, longevity, and lower thermal management costs. The UVC Ceramic PCB™️ is compatible with all 3-pads for full customizability.

The UVC Ceramic PCB™ integrates two groundbreaking technologies:

  • Super Pillar™ – for unmatched thermal dissipation

  • 3-Pad Flip Chip™ (from Flip Chip Opto) – for increased optical output and extended lifespan

Together, these innovations provide:

  • Higher lumen output

  • Longer LED service life

  • Lower thermal management costs

  • Full customization compatibility with all 3-pad designs

High Power + Low Thermal Resistance

  • Patented 3-Pad Flip Chip Technology

  • 1200W ~ 300W LED Module

  • Lower thermal management cost

  • Lowest Tj = Longer Life Span

  • Minimal Thermal Decay

  • Flip Chip Opto is perfect for UVC (High T/O ratio)

COFAN’s Innovative UVC Ceramic PCB™ Solution

COFAN has engineered the UVC Ceramic PCB™ to overcome these challenges using its patented Super Pillar™ technology on a ceramic substrate.

Key Benefits:
  • Ultra-high thermal conductivity – up to 390 W/mK, more than 100× higher than conventional MCPCBs

  • Direct thermal path – the Super Pillar™ bypasses dielectric pre-preg, transferring heat directly to the copper base

  • Superior durability – ceramic substrates resist UVC degradation, ensuring longer operating life

  • Reduced operating costs – optimized thermal management lowers cooling requirements

This combination enables greater reliability, higher efficiency, and long-term cost savings for UVC LED systems.
