IRC's Anotherm thermally-conductive aluminum alloy substrate is insulated by a thermally conductive, chemically grown, anodized dielectric layer with solderable screen printed conductors applied to the anodized layer. Said to provide effective thermal management, which is a key requirement in efficient LED operation, the substrate material enables design engineers to mount visible LEDs and other components directly to it. This eliminates the need for attached heat sinks and mounting hardware as well as the associated assembly costs.

The LED assemblies can be developed with up to three layers of circuit on a single Anotherm board. The Anotherm substrates feature an insulation system consisting of a thin layer of anodized aluminum oxide, producing a dielectric layer approximately 0.0014 inches thick (0.035 nm), which provides an inorganic insulation that is not affected by temperature or chemical exposure. This construction gives Anotherm technology the ability to operate in extreme temperatures up to 175°C. The maximum operating voltage is 250 Vac, and thermal impedance is characterized at 0.02°C/W. Anotherm substrates are available RoHS compliant. Click the link for more information about the Anotherm technology.

This Anotherm technology may also be used in automotive applications.

Prototypes of the populated LED assemblies are available in about 6 weeks. Pricing and lead times vary for the custom populated LED assemblies.
