Point burning device for superfine wire pulling mold penetrating

The utility model discloses a point burning device for superfine wire pulling mold penetrating, which utilizes an electrochemical corrosion principle for placing a bonding wire head part into conductive brine solution to generate current so that the bonding wire head part becomes thinner, and the wire pulling mold penetrating requirements are met. The point burning device comprises a 220V alternating current power supply, a voltage reduction transformer, a switch, a solution box, a support frame, a section of titanium wire, the brine solution and a plurality of conducting wires. The device is simple and practical, no pollution is caused, the problem of superfine wire pulling mold penetrating is solved, and the production efficiency is greatly improved.
