The 1634-12S is a no-clean Flux Remover (defluxer) removes 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. G3®, Ecoline™ and Precision-V™ flux removers have been proven very effective at removing fluxes baked on at lead-free temperatures. Micro-components and fine pitch leads are delicate and easily damaged, so brushing and scrubbing should be avoided if possible. Both G3, Ecoline and Precision-V have a powerful spray and strong solvent that blasts off residues and cleans areas under components that a brush cannot touch. The power of G3, but specifically formulated to avoid and clean white residues caused by no­clean fluxes and proven effective for lead-free processes. It is in the form clear colorless liquid with faint ethereal odor.
