Flexible and Rigid-Flex PCBs: When Should You Use Them?
As electronic products become smaller and more complex, traditional rigid PCBs are not always the best solution. When designs need to fit tight spaces, reduce weight, or withstand movement, flexible and rigid-flex PCBs offer major advantages. What is a Flexible PCB? A flexible PCB is a printed circuit board built on a bendable substrate that allows it to twist or fold without damaging the circuit. These are ideal for compact devices such as wearables, medical instruments, cameras, and handheld electronics. Key benefits include: Flexibility in tight spaces Reduced wiring and
