Water Soluble Flux Vs No Clean Flux

Water washable and 2.

Water soluble flux vs no clean flux. There are basically two types 1. If a company is using a full rosin or water soluble flux in their selective soldering process they are usually. Specifically the goal of the flux is to remove any oxides of the metal surfaces that may interfere with the soldering process causing a poor solder joint to form. There are several reasons to remove no clean flux residues from pcbs.

In terms of leaving a clean appearance no clean solder pastes are as good as any of the water soluble solder pastes says dixon. Water soluble generally uses organic acid activators as the flux and every component in the flux system should be soluble in water and therefore clean with only water. No clean flux is a mixture of organic resins aside from rosin mixed with certain inorganic agents. Water soluble flux the purpose of flux is to help create strong solder joints by first cleaning the metal surfaces.

Most high rel people traditionally have used water soluble fluxes because they re stronger fluxes they give a more robust soldering process and they re easier to clean. The fluxes in most of today s no clean pastes contain 50 percent to 70 percent solids. Organic flux is more reactive than rosin activated flux and is thus a stronger cleaner. Water washable flux may contain rosin and in addition a surfactant to remove the flux residue after reflow.

You can also find inorganic water soluble flux which is even more powerful than water soluble flux no clean flux.
