Lödband

Lödband, also known as solder tape or desoldering braid, is a copper braid coated with flux. It is used in electronics for removing solder. The braid is placed over a solder joint, and a soldering iron is applied to it. The heat from the soldering iron melts the solder, and the copper braid wicks it up, effectively removing it from the joint.

The process works due to the capillary action of the copper braid and the flux that is incorporated into the braid. The flux helps to clean the solder joint by dissolving any oxides that may have formed, which allows the solder to flow more easily onto the braid. Once the solder is absorbed into the braid, the braid is then removed, leaving a clean joint that can be resoldered or reworked.

Lödband comes in various widths and lengths, and the choice of braid depends on the size of the solder joint and the amount of solder that needs to be removed. Finer braids are suitable for small, delicate components, while wider braids can handle larger joints or pooled solder. The flux type can also vary, with different formulations suited for specific types of solder and applications.

Using lödband is a common technique for desoldering components during repair, prototyping, or rework. It provides a relatively clean and efficient way to remove unwanted solder without damaging the surrounding components or the printed circuit board. After use, the desoldered braid is typically discarded.
