A. The residue in dissolved flux that has not been

washed off the board. Cleaning flux off a circuit board

is more involved than simply spraying a cleaner onto it.

Removing flux is a two-step process. The first step is dissolving the flux. The

second step is rinsing off the dissolved flux. The rinsing step is very important

because after dissolving the flux it may appear that the solids in the flux have

disappeared, but once the flux remover has evaporated away, the solids will

re-deposit on the board as white residue.

Step 1: Dissolving the Flux

If you are using flux remover in aerosol form, spray a little flux remover onto the

flux, then agitate with a hog hair cleaning brush. If you are using our 4140 Flux

Remover, you may spray it liberally, as it is safe on your components. If you are

using 413B Heavy Duty Flux remover, you may spray it liberally on the solder side

of the board, but be careful to only apply it directly to the flux contaminated area

if you are using it on the component side of the board, as it will harm some

components. The 4140 is plastic safe so it may be applied liberally. Have a can of

413B handy in case you run into a patch of burnt-on difficult to remove flux.

If you are using flux remover in liquid form, pour the flux remover into a tray. If you

are using 4140 Flux Remover, you may then submerge the PC board into the tray,

agitating the flux with a hog-hair brush. If you are using 413B Heavy Duty Flux

Remover, you should not submerge the board into the tray, as the components will

be damaged. Instead, wet the hog-hair brush you are using by dipping it into the

tray, and then use it to agitate the flux on the board. Periodically rinse and re-wet

the brush by swishing it in the flux remover.
