A while ago, [drygol] was asked to repair a few old Amiga keyboards. The key switches worked fine, but in the past decade or two, the flexible PCB ribbon connector has been mistreated, and was in an ...

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, ...

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 ...

Test is becoming increasingly complicated as new technologies such as flexible electronics begin playing mission-critical roles in applications where electronics have little or no history. Although ...

• 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 ...

Rigid flex circuit design, like flex circuit design, is more complex than PCB design because it involves three dimensions. It also requires accurate prediction of path lengths and folding allowances, ...
