Cambridge Nanotherm Announces Enhanced Substrate for LED Thermal Management


cambridge nanotherm, a uk producer of innovative nanoceramic thermal management technology for leds, has announced the launch of “nanotherm dmth,” which is an enhancement to its award-winning nanotherm dm line of thermal management substrates.

 

according to a press release from the company, nanotherm dmth is “a double-sided substrate interconnected by laser-driller 100um through-hole vias.” the enhanced product is based on the company’s patented electro-chemical oxidation process that gives it higher levels of thermal conductivity. this maintains low led die temperatures, which lead to longer lifespans and better color rendering.

the nanotherm dm uses “uses thin-film circuitisation techniques to sputter a copper circuit trace directly onto the nanoceramic layer,” according to the release, which gives it a conductivity similar to electronics grade ceramics like aluminum nitride. this allows improved heat dissipation into the heat sinks that the nanotherm dm sits above.

 

the dmth takes that technology a step further by laser-drilling through-hole vias into the aluminum. the release stated, “when it goes through the eco process the surface of the vias is converted to a nanoceramic along with the rest of the aluminum to create a perfect dielectric.”

 

the vias are filled with copper to provide “electrical interconnections between the top and the bottom side of the circuit; from the pcb module connected to the power, through the bottom of the substrate and up to the led chip on top.”

 

cambridge nanotherm said that this product’s applications range from automotive headlights to uv leds for printing.
