Control of the effect of lead spot Welding on Capacitor Breakdown:

 

1. Establish the control document of the lead welding process in winding process, and clarify the welding status requirements of the lead and aluminum foil. For the welding quality of the capacitor core group, the operator must check himself regularly, such as the first piece inspection before boot. Inspector's inspection, special inspection, etc. Establish a perfect quality assessment system to ensure that the welding status of the lead line meets the requirements.

2. The pressure of the two electrode heads and the adjustment of the spot welding current should be moderate when the lead wire is welded, the spot welding platform shall be flat without grooves, the welding state of the lead wire and the aluminum foil shall be smooth and smooth on both sides, and no burrs shall be allowed. At the same time, the welding of lead wire and aluminum foil should be firm, shall not lead to fall off and aluminum foil fracture phenomenon. The flattening degree and length of the lead must be moderate.
