Desoldering Braid, Wick, PumpsDesoldering braid, also known as desoldering wick, is a type of copper braid that is used to remove excess solder from a circuit board or other electronic component. The braid is placed over the solder joint, and heat is applied from a soldering iron or other heat source. This melts the solder, which is then drawn into the braid by capillary action, leaving the joint clean and free of excess solder. Desoldering braid is commonly used in the repair and rework of electronic circuits. It is available in various widths and lengths to suit different applications, and can be used with or without a desoldering pump. A desoldering pump, also known as a solder sucker, is a hand-held tool that is used to remove excess solder from a joint. The pump consists of a spring-loaded plunger and a vacuum chamber, and is used by pressing the tip against the solder joint and releasing the plunger to create a vacuum that sucks up the molten solder. Desoldering pumps are often used in conjunction with desoldering braid to remove excess solder quickly and efficiently.
