Techspray no-clean wick does not leave behind ionic flux residues that can collect and form branches called "Dendrites". Other fluxes, if not cleaned properly, can cause Dendrites that grow over time and eventually cause short circuits between traces or leads. Latent failures lead to costly returns and lower the quality perception of your products. - Techspray desoldering braid (wick) is pre-fluxed copper braid that is used to remove solder, which allows components to be replaced and excess solder to be removed. Techspray wick is available in static dissipative bobbins (except where indicated) for static sensitive environments.
