What is solder wick and how does it work?
Solder wick, also known as desoldering wick or desoldering braid, is a tool used to remove excess solder from electronic components and printed circuit boards (PCBs). It is a braided copper wire coated with a flux that helps to absorb and remove solder. When the solder wick is placed on top of the excess solder and heated with a soldering iron, the flux is activated, and the copper braid absorbs the solder, allowing it to be easily removed.
The solder wick works by capillary action, where the braided copper wires draw in the molten solder, and the flux helps to break down the surface tension of the solder, making it easier to absorb. The solder wick is a simple yet effective tool that is essential for any electronics enthusiast or professional. It is available in different widths and lengths, and the choice of solder wick depends on the specific application and the amount of solder that needs to be removed.
