[0002] Printed Circuit Board (PCB) is an important electronic component and a carrier for the electrical connection of electronic components. With the rapid development of intelligent electronic devices, the use of PCB is increasing day by day. Antennas are often connected to PCBs, and an antenna feeder is set at one end where the antenna is connected to the PCB for transmitting and receiving signals. In the related art, the antenna feeder is directly soldered on the PCB, or an IPX interface or SMA interface is installed on the PCB, and then the antenna feeder is fixed.

[0003] Announcement No. CN215420923U discloses a circuit board and a circuit board assembly, including a body and a feeder stopper disposed on the board body. By arranging a feeder line slot penetrating the feeder line stopper on the feeder line stopper, the antenna feeder can be positioned on the board body, so that the antenna feeder has a certain routing direction on the circuit board, thereby reducing signal interference to electronic components on the circuit board;

[0004] When in use, the device is convenient and quick to connect, but difficult to disassemble. If it is easy to disassemble, the connection tightness is low, which makes it time-consuming and laborious for workers to maintain the circuit board in the later stage; therefore, we propose a circuit board and a circuit board assembly.
