Through the elastic force of the elastic lining 6, the circuit board to be welded is fixed between the adjustment plate 4 and the positioning plate 5, that is, the circuit board to be welded is fixed on the substrate 1.

[0024] After the circuit board body 3 is fixed, the pressing plate 2 is rotated to make the elastic pad 7 of the pressing plate 2 tightly attached to the substrate 1. The elastic pad 7 relies on its own elastic force to tightly attach to the back of the circuit board body 3, thereby further positioning the circuit board body 3. When the elastic pad 7 contacts with the circuit board body 3, no damage will be caused to the circuit board body 3.

[0025] A first magnetic strip 12 is disposed on the positioning plate 5 of the base plate 1 , a second magnetic strip 13 is disposed on the pressing plate 2 , and the second magnetic strip 13 is fixed to the first magnetic strip 12 by magnetic attraction.

[0026] Among them, when the pressing plate 2 is pressed on the substrate 1, the first magnetic strip 12 of the substrate 1 and the second magnetic strip 13 of the pressing plate 2 are tightly attached, and the two are fastened by magnetic attraction. After the fixation is completed, a certain external force is applied to the substrate 1 to make the substrate 1 rotate along the fixing block 15, rotate one hundred and eighty degrees, and turn the welding surface of the circuit board to be welded upward. At this time, the welding positioning of the circuit board to be welded is completed, ensuring the stability of the circuit board to be welded during the welding process and improving the welding quality.
