[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed (copper etching technology) circuit board, etc.; since the existing component body is only soldered on the surface of the circuit board during installation, the stability is insufficient, so the existing Chinese patent with authorization announcement number CN210745660U discloses an anti-falling circuit board, whose structure includes a circuit board body, mounting holes, components, tin soldering pins, pin fixing devices and fixing devices, by setting a fixed pin between the circuit board body and the lower part of the outer surface of the component The fixing device is configured to provide traction when the component is placed in the groove and to be clamped at the upper end of the inner side of the top block. The spring on the inner side of the movable groove provides elastic force to press the component at the top block, and the rubber layer on the inner side of the top block improves the stability of the friction resistance, thereby achieving the beneficial effect of increasing the fixation of the component body by adding a fixing component; and a needle fixing device is provided on the lower part of the outer surface of the soldering needle, which is pulled by inserting the oblique mouth, and the bent needle groove is used to bend the soldering needle to increase the clamping force. The space increased by the retention groove during soldering fixation improves the stability of the soldering, thereby achieving the effect of adding multiple tin material components to improve the position fixing ability of the soldering.

[0003] However, in actual applications, the above-mentioned circuit board still has the following shortcomings: before welding, the above-mentioned component body needs to be drilled with retention grooves, bending needle grooves, movable grooves and grooves. During the drilling process, the circuit inside the circuit board body is easily damaged, affecting the normal use of the circuit board body; in addition, when welding the component body, the original part needs to be inserted into the groove and pressed down before the pins of the component body can be welded. The welding process is not convenient, resulting in low welding efficiency of the component body and reducing the production efficiency of the circuit board body. Utility Model Content
