LED thermal management innovator Cambridge Nanotherm launched Nanotherm MCPCB — a thermally-efficient and cost-effective metal-clad PCB. Thanks to a recent technological breakthrough regarding the company’s patented electro-chemical process, which creates a 20 μ-thick dielectric layer of alumina atomically bonded to the aluminium board, they have been able to radically drive down the cost of the metal-clad PCB, which is now available to customers at a lower cost but better efficiency.

The MCPCB offers a thermal efficiency of 120 W/mK, offering electronics designers better than 56 % of the thermal conductivity of an aluminium plate. It also offers a robust stability at an operating temperature of 130 °C, and is lead-free solder compatible and ROHS and UL recognised.

This price reduction brings the company’s revolutionary ceramicised aluminium boards, which used to be only affordable for high-power applications, solidly within the price range of all general lighting applications for the first time.

The sales and Marketing Director Mike Edwards said: “The fact that our Nanotherm MCPCB is now available to the general lighting market is testament to the hard work and research our scientists have put in over the past three years. One of our greatest strengths is that we can easily ‘swap in’ our thermal management technology to customers’ existing MCPCB machining processes, but we are particularly dominant when it comes to integrating CSP designs into tuneable white solutions. Where a company may have previously used a traditional MCPCB, now they can use Cambridge Nanotherm’s technology, gaining greater thermal efficiency at a lower price, with no costly retooling and minimum integration effort.”

The company’s MCPCB is now available for prototyping and mass production orders. Industry-standard copper finishes, solder mask and feature sizes are all available — as are double-sided substrates containing a dielectric surface and wiring traces on both sides of the MCPCB.
