Water Soluble Flux Vs No Clean Flux

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

Water soluble flux vs no clean flux. Water washable and 2. 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. Organic flux is more reactive than rosin activated flux and is thus a stronger cleaner. 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 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. The fluxes in most of today s no clean pastes contain 50 percent to 70 percent solids. 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. Water soluble flux the purpose of flux is to help create strong solder joints by first cleaning the metal surfaces.

Bittele s use of flux in pcb assembly no clean flux vs. There are several reasons to remove no clean flux residues from pcbs. Because with rosin you need to use some sort of chemistry either a saponifier in a water based system or another solvent. Water washable flux may contain rosin and in addition a surfactant to remove the flux residue after reflow.

No clean flux is a mixture of organic resins aside from rosin mixed with certain inorganic agents.
