Optek Technology has developed a thermally conductive aluminium substrate, which provides solid state lighting design engineers with a means of dissipating heat in visible LED applications. 

The OptoTherm 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 four KV DC. Copper and aluminium 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 OCB201 Series is 18x16.5inches, with available thicknesses of 0.038" (0.97mm), 0.070" (1.78mm), and 0.133" (3.38mm).
