FLEX CIRCUIT DESIGN
Ensuring First-Time Success in Rigid-Flex PCB Layout

For designers of products such as wearables, where every cubic millimeter of space within the enclosure is used, and two or more PCBs must be folded into place in final assembly, flex is becoming a popular choice for more than just a replacement for cable. One flex section can replace a cable plus two connectors, offering cost savings on top of the space benefits.
