UVC Ceramic PCB™ Technology
UVC light is rapidly becoming a popular choice for air, water, and surface sterilization due to its inherent ability to render pathogens harmless without the use of harmful chemicals. UVC LED technology is revolutionizing the industry by providing a clean alternative to the standard, but toxic, mercury vapor lamps.
Whether it is water disinfection in residential applications, public water systems, swimming pools; surface sterilization in hospitals, packaging facilities; or air disinfection in buildings, UVC LEDs emerge as a winner due to their versatility, small form factor, and their low power consumption.
While UVC LEDs have clear advantages, the heat generated and the radiation produced prevents it from being a cost-effective solution. Conventional MCPCBs utilize an organic dielectric layer which slowly degrades due to UVC exposure, limiting its longevity.
COFAN's innovative UVC Ceramic PCB™ design addresses both problems by utilizing our newly patented Super Pillar™ technology combined with a ceramic substrate. The Super Pillar™ technology delivers exceptional thermal conductivity—up to 390W/mK, which is more than 100 times the heat dissipation of a conventional MCPCB. The Super Pillar™ achieves this impressive feat by bypassing the dielectric pre-preg and adding a direct thermal path to the copper base. Additionally, ceramic substrates provide excellent thermal dissipation and resistance to UV radiation.
