Rigid Flex PCB_Hitech Circuits

What is rigid-flex pcb board?Rigid-flex PCB board, it is a circuit board that combines flexible and rigid circuit board technology in the application. Most rigid-flex boards are composed of multiple layers of flexible circuit boards, which are attached to one or more rigid boards from the outside and/or from the inside, depending on the design of the application. The flexible substrate is designed to be in a constant deflection state, and is usually formed as a deflection curve during rigid flex pcb manufacturing or assembly.https://hitechcircuits.com/pcb-products/rigid-flex-pcb/
