In this e-book, readers will gain a thorough look at flexible printed circuit materials, fabrication processes, and design challenges. These and many other questions reflect the challenges of rigid-flex PCB design.

How are placement and routing within flex regions different from that of traditional rigid PCBs?.

How can the range of flex motion and critical folding lines be modeled and verified?.

How are the different rigid and flex materials and layer specifics managed and communicated to a fabricator?.

How are dissimilar rigid and flex sections described in a single PCB assembly?.

How much will rigid-flex cost to fabricate and assemble?.

However, as many PCB designers contemplate designing rigid-flex PCBs for the first time, several challenges come to mind: Today, it is recognized as an ideal solution in electronics assemblies with small form factor and in highly durable, lightweight electronic products such as wearables, medical devices, and mobile wireless products.

Rigid-flex PCBs are a time-proven, well-understood technology initially used within the military/aerospace industry decades ago. This guidebook is an attempt to clearly explain the materials, processes and design issues in a way that will enlighten PCB designers of any level.This paper highlights several key considerations for rigid-flex design. Today’s small lightweight consumer electronics products are best implemented with rigid-flex technology, however, there can be many challenges in achieving successful rigid-flex PCB designs. Rigid-flex PCB technology offers tremendous benefits in terms of reduced weight and space, however flex assemblies can have greater durability and reliability.
