Substrates manage LED heat dissipation
Substrate material enables design engineers to mount visible LEDs and other components directly to it, eliminating the need for attached heatsinks, mounting hardware and assembly costs.
Providing lighting system design engineers with a complete solution for their illumination and display applications, TT electronics IRC Advanced Film Division now offers populated LED assemblies The assemblies are constructed using IRC's Anotherm technology, a thermally conductive aluminium alloy substrate insulated by a thermally conductive, chemically grown, anodised dielectric layer, with solderable screen printed conductors applied to the anodised layer

Substrates help LEDs burn brighter for longer
Anotherm substrate technology is ideal for LED display applications in gaming and vending machines, outdoor signage and display, emergency vehicle lighting, and architectural and general lighting.
The substrate material enables design engineers to mount visible LEDs and other components directly to it, thus eliminating the need for attached heatsinks, mounting hardware and the associated assembly costs.
"Our Anotherm substrates provide the effective thermal management that is critical to efficient LED operation and extended LED life", said Tom Morris, Applications Engineering Manager for IRC's Advanced Film Division.
"Our capability of providing populated LED assemblies on Anotherm substrates provides our customers with a turnkey solution for developing new LED lighting products".
The Anotherm substrate technology is being specified for a variety of high-brightness LED display applications, including gaming and vending machines, outdoor signage and displays, emergency vehicle lighting, and architectural and general lighting.
IRC will develop prototypes of the populated LED assemblies in about 6 weeks, Morris continued.
The devices 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 anodised aluminium oxide that is chemically grown on the aluminium core, producing a dielectric layer approximately 0.035nm thick, which provides an inorganic insulation that is not affected by temperature or chemical exposure.
This rugged construction gives Anotherm technology the ability to operate in extreme temperatures - up to 175C.
Maximum operating voltage is 250V AC, and thermal impedance is characterised at 0.02C/W.
IRC's Anotherm substrates are available RoHS compliant.
Pricing and lead times vary for the custom populated LED assemblies.
