The electrode plate passes through the welding hole 201 on the circuit board 200, and after the circuit board is positioned, the electrode plate is welded on the welding disc 202 of the circuit board by adopting tin soldering.
The supercapacitor module needs a tool clamp to fix the monomer in the welding process, so that the monomer is prevented from deviating in position, and the welding stability is ensured. In the prior art, the tooling clamp limits the positions of the capacitor monomer and the circuit board without redundancy, so that the circuit board cannot be accurately positioned or positioned, and the circuit board is seriously deformed and damaged in the welding process.

When the prior art is used for welding, an ordinary soldering iron head can only be contacted with a bonding pad, but the bonding pad is large, so that heat cannot be accurately conducted to the whole bonding pad. In the prior art, a mode that a soldering bit is contacted with an electrode plate is adopted, however, a welding hole is larger than the electrode plate, and the electrode plate is deviated in the hole, so that a common soldering bit cannot be contacted with the electrode plate every time. Due to the particularity of the structure, the common soldering bit can not meet the welding requirement.
