Metal-backed PCB reduces LED device temperature by up to 20°C
January 14, 2013 // Julien Happich
The culmination of two years of development using Cambridge Nanotherm's ceramic dielectric technology, Nanotherm MBPCB (Metal-Backed Printed Circuit Board) is an innovative thermal management material with a dielectric thermal conductivity of 7 W/mK.
This means the metal-backed PCB is able to significantly reduce LED die temperatures, even in the most thermally challenging luminaire designs. The company’s core IP is in its unique process for converting Aluminium into Alumina (Al2O3), allowing the surface of an Aluminium plate to be converted into a layer of Alumina as thin as 10 micron, which acts as a dielectric. A range of standard PCB fabrication techniques can then be used to apply circuitry onto the nano-ceramic dielectric layer.
Independent testing of the Nanotherm MBPCB in LED lighting applications has shown that it offers a 20% reduction in substrate thermal resistance over some of the best available metal-backed PCBs. In back-to-back comparison testing with other metal-backed PCBs, LED temperatures were seen to be reduced by as much as 20°C, thus allowing designers to increase component density and power or give longer lifetime guarantees.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
