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:
- Excessive heat generation that reduces efficiency
-
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.
Advantages
Increases the lifespan of the UVC LED
Reduces mercury content
Drives higher lumen for better sterilization
Utilizes lower cost pre-preg
Innovative Process
Uses UV-resistant ceramic instead of epoxy
Uses patented Super Pillar™️ and 3-Pad Flip Chip™️ technology to dissipate the extreme heat
