This small 1.5m reel of 2.0mm copper braid is something that no solderer should be without. The braid allows you to mop up the excess solder on a joint to help clean up your board. We use it ourselves on our in house boards and could not imagine soldering without it.
The braid functions by providing a large surface area for the solder to flow to. It can be used by resting the braid accross the joint to be cleaned. Following this simply apply heat to the braid above the joint with your soldering iron. After a short moment the solder will begin to flow into the braid, all while leaving the joint clean without excess. This does take a little practice to get right, but once mastered it is a fantastic tool.
