You can now make flexible circuit boards of unlimited length. Trackwise was contracted out for making a wiring harness for the wing of a UAV and managed to ship a 26 meter long flexible printed circuit board. This is an interesting application of the technology — UAVs are very weight sensitive and wiring harnesses are heavy.
Wings are straight, but they flex, and you need wires going from tip to tip. Flex circuits do all of this well, but first you need a technology that allows you to manufacture circuits that are as long as a wing. This is apparently something called ‘reel-to-reel’ technology, or some variant of continuous production. Either way, it’s cool, and we’re wondering what else this kind of circuit enables.You may have noticed a few odd-shaped buildings going up in the last few years. These are buildings…
