You’ve likely seen this on the bench or in the field. A high-power LED build looks solid during testing but fails prematurely in the real world. The weak link usually isn't the driver or the chip; it’s the board itself. Standard FR4 boards act like thermal blankets, trapping heat exactly where it destroys the junction. If you’re pushing real power—anything beyond a simple indicator—an aluminum PCB isn't a luxury upgrade. It is an engineering necessity to protect your investment from the inevitable thermal load.
The Hidden Heat Problem That Destroys BuildsHigh-power LEDs generate intense heat in a focused surface area. Unlike incandescent bulbs that radiate heat outward, LEDs conduct it down through the package. Here’s the friction point: standard FR ...
