Solder Flux Cleaning Process

Activate the flux of the solder by heating the iron to 482 f 572 f 250 c 300 c then clean the tip with brass will or an automatic tip cleaner.

Solder flux cleaning process. There are all purpose heavy duty no clean rosin and water soluble flux removers. Afterward flux residue can be removed from the solder joint with commercial flux removers. Soldering forced hot air convection ir wave single and dual 2. The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities.

The flux acts as an agent to clean oxidation from the surface of the metal so that the melted solder can flow. It is basically used to clean surface of pcb before soldering process. Using wire solder and water soluble flux for touch up and rework operations will still hasten tip failure. Fluxes may have more than one function at a time.

After soldering we using vapor degreaser process with rho tron 225 aes l to clean up the flux. Flux is used in both manual hand soldering as well as the different automated processes used by pcb contract manufacturers. Flux compositions used for wave soldering paste flux and solder paste compositions have transitioned from liquid rosin based fluxes to low residue no clean and water soluble fluxes. It helps to clean and remove oxides and other impurities and thus helps in wetting.

This very mild cleaning action normally isn t thorough enough to remove oxidization from soldering iron tips. Recommended use sn 63 pb 37 solder paste. Cleaning solvent aqueous semi aqueous no clean 1 reflow general use the optimum solder paste for the pattern printing process solder paste density and solder joint quality. They are used in both extractive metallurgy and metal joining.

Wire freshly coated with solder still immersed in molten rosin flux in metallurgy a flux derived from latin fluxus meaning flow is a chemical cleaning agent flowing agent or purifying agent. For more stubborn rust you may need to use a tip tinner. A safe solvent cleaning process that offers numerous environmental benefits and has the ability to solvate no clean flux residues fills a void for cleaning highly dense assemblies soldered with modern flux technologies. Following soldering and cleaning processes.

Another type of flux no clean flux is only for soldering parts that require little to no cleaning. The flux components within solder paste have become highly complex with a highamount of variability among the no clean rosin. Most come in aerosol cans and are sprayed after the solder. For soldering on our production lines we using kester solder sn 63 pb 37 with flux 245 no clean in addition we using kester flux 959 977 2331 zx.

Rosin flux is manufactured from a type of resin obtained from pines and some other plants.
