What are Rigid-Flex PCBs? Rigid-flex PCBs are a type of printed circuit board that combines both rigid and flexible substrates. The rigid parts of the board provide structural support and stability, while the flexible sections allow for bending, folding, or twisting. This unique design enables engineers to create three-dimensional configurations and save space in electronic…
