Description

Circuit board welding spot trimmer

Technical Field

The utility model relates to a solder joint technical field is maintained, specifically is a circuit board solder joint trimmer.

Background

Whether the electronic components on the circuit board are welded manually or by a machine, cold joint or welding point sharpening and the like can occur. The pointing refers to the sharp-angled bulge of the solder on the welding spot of the copper foil circuit terminal of the circuit board, and the sharp-angled bulge has an obvious tip, and the situation is called welding spot pointing.

The solder joint pinching may occur due to the operator's hand removing the tip too early when the solder is not completely melted and solidified or due to the temperature being too low during soldering. However, the most causes are the fact that the torch head is removed too late, the welding time is too long, and the flux is vaporized, i.e. the tip is temperature and operation dependent. In this case, the appearance of the solder joints of the circuit board is not good, and when the solder joints are pulled to a tip exceeding the allowable length, the insulation distance between the solder joints is reduced, which is likely to cause bridging. Generally, the welding point is required to be filed off by a file, but the welding point of the circuit board is difficult to fix and trim by pricking hands.

In order to conveniently fix and repair the drawn sharp welding spot of the circuit board, the welding spot trimmer for the circuit board is provided.
