[0002] PCB is also known as the circuit board. The main function of welding nickel sheets on PCB boards is to improve wear resistance. Nickel sheets are used as a substrate plating for gold, especially on surfaces subject to heavy wear, such as switch contacts, contacts or plugs. It can greatly improve wear resistance. Moreover, on PCBs, nickel is not only used as a substrate plating for precious metals and base metals, but also as a barrier layer, which can effectively prevent the diffusion between copper and other metals. In addition, nickel sheets can also be used as an etch-resistant metal plating, which can meet the requirements of hot pressing and brazing.

[0003] Since the SMT soldering end of the nickel sheet is parallel to the soldering end of the battery pack, although a magnet is designed to assist in fixing the nickel sheet in position, it is easily affected by the tension of the solder during the soft-melt soldering process, resulting in unstable movement and deviation. Therefore, a PCB board and soldering carrier are needed to prevent soldering deviation of electronic components. Utility Model Content

[0031] The plane of the battery pack soldering end 14 is lower than the PCB soldering end 10. The retaining grooves 4 provided on the carrier body 1 on both sides of the accommodating groove 2 limit the battery pack soldering end 14 of the nickel sheet body 5. Compared with the traditional design in which the battery pack soldering end 14 is flush with the PCB soldering end 10, this structure makes the nickel sheet body 5 less susceptible to the tension of the solder during the reflow soldering process, preventing unstable movement and deviation.

The PCB welding end 10 is connected to the PCB board body 3. The plane of the battery pack welding end 14 is lower than the PCB welding end 10. The carrier body 1 on both sides of the receiving groove 2 is provided with a limiting groove 4 to limit the battery pack welding end 14 of the nickel sheet body 5, so that the nickel sheet body 5 is not easily affected by the tension of the solder during the soft melting process, thereby preventing unstable movement and offset. Magnetic auxiliary areas 6 are provided on both sides of the PCB board body 3. Fixed parts 9 are provided on the magnetic auxiliary areas 6. The fixed parts 9 are made of magnet sheets, so that the PCB welding end 10 of the nickel sheet body 5 can be fixed by magnetic attraction, further preventing deviation during the soldering process.

No other devices are distributed in the vacant area 7 to prevent the electronic components 8 around the magnetic auxiliary area 6 from being affected by the magnetic field and being attracted and moved by the magnet, thereby avoiding the influence of magnetic force. By optimizing the design of the nickel sheet body 5 and the layout of the PCB board body 3, the yield of the nickel sheet machine is significantly improved.
