Trackwise has shipped a 26-metre long multilayer, flexible printed circuit (FPC), believed to be world’s longest ever produced, for distributing power and control signals across the wings of a solar-powered, unmanned aerial vehicle (UAV). The circuit is one of over fifty supplied by Trackwise into this vehicle.

The entire interconnect system (power and signal) of the vehicle is made of FPCs representing an estimated total systems weight saving of 60% over traditional wire harness. This will enable the UAV, which is being manufactured in the US, to achieve higher payload and/or improved speed and range. The FPCs are manufactured using Improved Harness Technology (IHT), a patented, reel-to-reel manufacturing technique. Conventional FPCs are rarely more than two metres in length, primarily due to limitations of manufacturing processes. IHT overcomes these limitations, enabling FPCs of unlimited length to be produced.
