This product has been retired from our catalog and is no longer for sale. This page is made available for those looking for datasheets and the simply curious.
Description: Replacement: None at this time. We are currently looking for a less hazardous flux pen, check back later for more information. This page is for reference only.
This is a water soluble liquid flux pen. A flux pen is a must have when performing any kind of solder rework. The flux is the substance that prevents beading of the solder and helps the solder flow cleanly onto the parts you are soldering. However, flux is mildly corrosive over long lengths of time (months). The water soluble flux will cleanly wipe away after wetting the soldered surface.
Check out our Surface Mount Soldering Tutorials for some great soldering examples!
Note: Due to restrictions with the flux pen, we are currently unable to ship this product. It is still available for local pickup if you’re in Colorado.
Be sure to use in a well ventilated area.
