Flexible PCB
What is Flexible PCB?
Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Flex boards are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material.
