What is a Rigid Flex PCB?

Rigid-Flex printed circuit boards are designed to provide solutions, and act as replacements for rigid PCBs. As the name suggests, these circuit boards are a hybrid of flex and rigid circuits. The advantage of this type is that they exhibit the benefits of both rigid as well as flexible circuit boards.
