Building electronics in unconventional form factors with high packaging density is possible thanks to three-dimensional circuit designs using flex and rigid-flex printed circuit boards (PCBs).

Flex PCBs have been a key enabler of modern high density electronics, but achieving this density requires thinner layers and finer lines. Conventional three-layer flex circuits comprised of copper, ...

In the last blog on rigid-flex PCBs, I talked about the fabrication processes typically used by board houses. It’s important to understand the steps required to build up a rigid-flex or flex circuit ...

Rigid-Flex can have many benefits, and many designers are at least considering it today who previously did not have to. More PCB designers are facing higher pressures to build ever more densely ...
