Water Soluble Flux Vs No Clean Flux

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.

Water soluble flux vs no clean flux.

If a company is using a full rosin or water soluble flux in their selective soldering process they are usually. 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. Because with rosin you need to use some sort of chemistry either a saponifier in a water based system or another solvent. 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.

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 washable and 2. No clean flux is a mixture of organic resins aside from rosin mixed with certain inorganic agents. You can also find inorganic water soluble flux which is even more powerful than water soluble flux no clean flux.

Bittele s use of flux in pcb assembly no clean flux vs. There are basically two types 1. Water soluble flux the purpose of flux is to help create strong solder joints by first cleaning the metal surfaces. Water washable flux may contain rosin and in addition a surfactant to remove the flux residue after reflow.

Organic flux is more reactive than rosin activated flux and is thus a stronger cleaner.
