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, ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

Flexible printed circuit boards (PCBs) aren’t much different than rigid boards during the design phase, except that the designer must account for the mechanical complexity associated with flex ...

• A flexible printed circuit is as much a mechanical device as it is an electrical device. • The neutral bend axis may not be in the exact middle of the material stack. • The reliability of flexible ...
