CARROLLTON, Texas, 10 March 2008. TT Electronics OPTEK Technology in Carrollton, Texas, has developed a thermally conductive aluminum heat-spreader substrate called the OptoTherm OCB201 series with high thermal conductivity for thermal management of visible light-emitting diode (VLED) assemblies.
The substrates offer a thermal path for removing heat from visible LEDs, with a dielectric that is 0.004 inches thick, says Alan Bennett, vice president of sales and marketing for OPTEK Technology.
The substrates feature a high isolation voltage, with a dielectric breakdown of 4 kilovolts DC. Copper and aluminum thicknesses are 0.0042 inches and 0.062 inches, respectively.
Maximum substrate panel size for the OptoTherm OCB201 series is 18 by 16.5 inches, with available thicknesses of 0.038, 0.070, and 0.133 inches.
