Desoldering Wick Desoldering wick, also known as desolder braid, is a handy tool made up of braided copper threads. Its purpose? To make desoldering faster and cleaner. When used in conjunction with a heated soldering iron, it works wonders in removing soldered joints. One of the great things about desoldering wick is its ability to effectively tackle solder that has gone astray. You see, sometimes solder ends up where it shouldn't be, like on a jumper or another unintended spot. That's where flux comes into play. By adding flux to the equation, it helps the solder flow away from its unwanted location and onto the wick, making the cleanup process much easier. It's amazing how versatile soldering can be. With the right tools, like solder wick, you can tackle a wide range of soldering tasks. So whether you're working on electronics or other projects that require precision soldering, having a roll of desoldering wick at your disposal is a smart move. It makes the desoldering process a breeze and ensures that your work is tidy and efficient.
