Desoldering Braid
Desoldering braid or desoldering wick is a pre-fluxed copper braid that is used to remove solder allowing components to be replaced and excess solder (e.g., bridging) to be removed. The soldering iron is applied to the wick as it sits on the solder joint, and when both reach the solder's melting point, the flux is activated and, through capillary action from the braided design, solder is drawn up the wick. Techspray wick has been a mainstay at PCB rework, repair and prototyping stations for over 30 years.
