How To Clean Soldering Flux

No cleans in theory contain lower total solids so as not to need removalcleaning.

How to clean soldering flux. Could you advice if our process is right and could you recommend any better solutions andor. Isopropyl alcohol is generally used for the removal of flux residues on circuit boards. The lower the total solids the fewer residues on the board.

Of baking soda with enough warm water to make a paste. If there is a significant amount of flux left on the piece or dirty solder consider using a soft brush to help with scrubbing. Take a clean brush.

If I leave it for a week after soldering so the flux thickens then I just have to leave it submerged for longer and maybe lightly brush it. To prevent damage to the board you should re-solder your soldering iron now and then as the technique will remove solder from it. If I just soldered the board I literally just have to dunk it in an ethanol bath gently swish the PCB around to agitate things a bit and tip it as I take it out.

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. The fluxes in most of todays no clean pastes contain up to 60 percent solids. Hi migs i use a flux removing spray you should get that from most electronic suppliers i use maplin or rapid electronics here in the UK.

Using a specially designed cleaner or brass to clean the soldering irons tip. This is because corrosive flux continues to damage the board if not removed. After securing and preheating the PCB and void in a vice or PCB holder you suck the solder off the board by squeezing and releasing the bulb from behind the hole.

Solder flux is used to remove the metal oxide surfaces that in the joining process prohibit a bond between the metals. At soldering temperatures flux chemically reacts with oxides in order to produce fresh tarnish-free surfaces. There are essentially three types of flux water soluble flux no-clean flux and traditional rosin flux.
