Circuit designers will no doubt agree that tools like solder wick are just as vital towards extending the life of a PCB as the resins used to protect components. Though MG chemicals has a host of products like conformal coatings and potting compounds to ensure the sustained performance of the circuit, sometimes it becomes necessary to completely replace components as a quick and economical means to keep the PCB functional. To replace components, it is necessary to melt the solder holding the component at the solder joint. A soldering iron or heat gun is used to melt the solder and solder wick or desolder braid is used to help the liquid solder flow away from the solder joint.
Desoldering braid is finely weaved copper wire which typically contains flux but is also available unfluxed. The braid is highly thermally conductive and efficiently transfers heat from the solder iron tip onto the solder joint, melting the solder. The flux in the desolder braid helps the liquid solder flow away from the solder joint and up the wick, effectively removing the solder so the component can be removed and replaced. MG Chemicals has a variety of solder wick available depending on your needs.
