CARROLLTON, TX (March 7, 2008) - Providing solid state lighting design engineers with a means of dissipating heat in visible LED applications, TT electronics OPTEK Technology has developed a thermally conductive aluminum substrate. Designated the OptoTherm(TM) OCB201 Series, the heat spreader substrates feature high thermal conductivity, creating a superior means of efficient thermal management for visible LED assemblies.

The substrates feature a high isolation voltage, with a dielectric breakdown of 4KVDC. Copper and aluminum thicknesses are 0.0042" and 0.062", respectively. Thermal conductivity is 1.1W/m-°K and thermal resistance is 1.8°C/W. The substrate meets UL-94 V0 flammability specifications.

With their in-house testing and third party validation, OPTEK will also verify that the substrate characteristics meet or exceed industry standards.

Maximum substrate panel size for the OptoTherm(TM) OCB201 Series is 18 x 16.5 inches, with available thicknesses of 0.038" (0.97mm), 0.070" (1.78mm), and 0.133" (3.38mm).
