Flux Remover Selection Guide

The Flux Remover Selection Guide from Techspray is designed to help you find the right defluxer for your application.  Flux removers (defluxers) remove flux residues and other contaminants left by manufacture, rework or repair of printed circuit boards.  Residues from higher, lead-free temperatures are more baked on and harder to clean.  Tehchspray flux removers have been proven very effective at removing fluxes backed on at lead-free temperatures.
