A method for manufacturing a rigid-flex board is disclosed. After the formation of each layer of the rigid-flex board, a laser-etched groove is formed at the interface between a rigid part and a bending area of the rigid-flex board. After the laser etching process, a circuit-board routing process is performed to remove materials along the sideward perimeter of the bending area. The exposed copper layer is then removed from inside the laser-etched groove. Thereafter, a redundancy rigid structure within the bending area is readily removed to expose the flex board within the bending area.
