Water Soluble Flux Vs No Clean Flux

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.

Water soluble flux vs no clean flux.

Water soluble flux the purpose of flux is to help create strong solder joints by first cleaning the metal surfaces. Water washable and 2. In terms of leaving a clean appearance no clean solder pastes are as good as any of the water soluble solder pastes says dixon. No clean flux is a mixture of organic resins aside from rosin mixed with certain inorganic agents.

Water soluble fluxes when discussing fluxes for the selective soldering process we are generally referring to low solids no clean fluxes and it is the most commonly used flux type in selective soldering. You can also find inorganic water soluble flux which is even more powerful than water soluble flux no clean flux. There are basically two types 1. Because with rosin you need to use some sort of chemistry either a saponifier in a water based system or another solvent.

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. Organic flux is more reactive than rosin activated flux and is thus a stronger cleaner. Bittele s use of flux in pcb assembly no clean flux vs. There are several reasons to remove no clean flux residues from pcbs.

If a company is using a full rosin or water soluble flux in their selective soldering process they are usually.
