Flux Remover

*=required field

Flux removers or 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. PWR-4™, G3®, E-LINE™ 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, E-LINE™ and Precision-V have a powerful spray and strong solvent that blasts off residues and cleans areas under components that a brush cannot touch. Techspray offers traditional solvent-based cleaners and cutting-edge water-based technologies marketed under the Techspray Renew™ brand.

TECHSPRAY RENEW™ branded cleaners are innovative solutions that combine the best of current “green” technologies to make the most powerful eco-friendly cleaners on the market.

Our flux removers have the following advantages:

  • Help create bright, shiny solder joints
  • Improve PCB reliability
  • Prevent conformal coating defects
  • Prevent corrosion from contamination
  • RoHS compliant

FAQ's

Do you need to clean no-clean flux?

No, not if your concern is only reliability problems from ionic contamination. No-clean flux contains minimal ionic material that is fully consumed when the flux is activated, or in other words, brought to soldering temperature. If all of the flux isn’t activated, like when you apply a lot of flux but only solder a small area, you still need to clean the PCB. If you are applying conformal coating, you should remove all flux residues, regardless of the type of flux. Most people understand that when painting something, the surface must be prepared so it is absolutely clean. Otherwise, the paint will quickly lift off the surface and peel off. The same logic applies to conformal coating, even when the contamination is from no-clean flux.

What is flux remover?

Flux removers (defluxers) remove flux residues and other contaminants left by manufacture, rework, or repair of printed circuit boards. Flux removers can be solvent based (e.g. isopropyl alcohol) or water-based, which are generally used in batch or in-line cleaning systems.
