Selection Guide Thermal Management For LED Applications Thermal Solutions For Long‑Term Reliability Of Power LEDs Henkel’s BERGQUIST brand Thermal Solutions Ensure Color Consistency And Maximum Lifecycles For Your LEDs. Cost of Heat Summary Light Emitting Diodes (LEDs) Better thermal management allows more forward current to be applied have been around for years, to the LED, which means more light and possibly reducing the number of primarily concentrated in such LEDs required for the desired light output. Maintaining a cooler assembly markets as cell phones, PDAs at an equivalent power equates to more light per die. and other consumer electronics. Since most of these products Circuit Board Comparison have relatively short lifecycles, Metal core PCB and standard FR‑4 are commonly used circuit board protecting LEDs wasn’t a primary materials in conjunction with Power LEDs. BERGQUIST’s THERMAL CLAD concern because the product dielectric is a thin, thermally conductive layer bonded to an aluminum would fail or become obsolete or copper substrate for heat dissipation (see illustration below). The key Bergquist TCLAD in a typical long before the LED failed. Today, to THERMAL CLAD’s superior performance lies in i
