- an RFPCB including a plurality of layers bonded to a PCB, and a rigid portion disposed on a first surface of the PCB, a flexible portion extending from the rigid portion, and among the plurality of layers
- One of the layers includes a first protruding portion protruding and extending from the rigid portion.
- a second alignment mark corresponding to the first alignment mark formed on the first surface of the PCB is formed on the first protrusion. The first protrusion at least partially overlaps the first alignment mark of the PCB.
- an RFPCB capable of identifying positional alignment with a PCB while being formed of multiple layers and having a high wiring density is provided.
