Flux Remover

Ask us how we can improve your process.

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. 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.

All Techspray 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

Guide to Solvent and Water-based Ultrasonic Cleaning
When you are removing tough soils like baked-on flux residues or heavy industrial greases, you can have the strongest solvent cleaner in the world (like those offered by Techspray), but you will still need some kind of agitation. You can brush, wipe, and use all manner of elbow grease, but none of that will get the job done faster and more consistently than ...

How to Clean Flux From Under Low Stand-Off QFN Components
Because of the low stand-off of QFN components (around ½-1 mil) common on printed circuit boards (PCB), it is very difficult to get enough contact time with a cleaner to break through the flux dam and break down all the residues. For proper cleaning, the following impacts effectiveness of the process: solvent match, contact time, and agitation. As ...

Cleaning Electronics with Isopropyl Alcohol
Chemicals are found throughout the electronic assembly and repair process, but no solvent is more common than isopropyl alcohol. It is universally used for cleaning and as a main constituent of fluxes, but how much do you really know about isopropyl alcohol? Isopropyl alcohol (CAS #67-63-0) is also referred to as IPA, isopropanol, 2-propanol, and even rubbi...
