Super Pillar™
Super Pillar™ Technology
COFAN USA has developed the newly patented Super Pillar™ technology which enables designers to bypass the dielectric pre-preg and dissipate heat more effectively than a conventional MCPCB. The Super Pillar™ bypasses the insulating pre-preg and adds direct metal on the t-pad to the metal on top of the pillar for a direct thermal path, a design proven to conduct more than 100x more heat than a conventional MCPCB.
In LEDs, this means a higher light output per watt, higher reliability, longer product life, and increased cost efficiency. Using the Super Pillar™ technology, COFAN has helped engineers overcome complex thermal management solutions, like UVC lighting. Our Super Pillar™ can be customized with either copper or aluminum; copper offers the best thermal dissipation but it is more expensive, while aluminum is cost-effective and still offers better thermal dissipation than conventional MCPCBs

As you can see from our test results, the Super Pillar™ MCPCB has an extremely low thermal resistance and effective thermal path when compared to a conventional MCPCB with the same power input. There is a significant temperature difference of ~56℃ within 80 seconds. The Super Pillar™ decreases the junction temperature drastically. Capture interval: 3-4 seconds. Time elapsed: ~ 80 Seconds.

Conclusion
Super Pillar MCPCB provides a direct thermal conductive path for high-power LEDs by bypassing the pre-preg layer. As a result, the optical efficiency increases while thermal decay decreases. This allows users to drive components at higher currents while still conserving energy. Super Pillar technology dramatically improves thermal conduction and decreases the junction temperature drastically.
