Rework Flux

Electronics Forum | Fri Oct 25 03:46:37 EDT 2002 | Adam

GUYS HOW SAFE IS IT TO USE RMA FLUX WHICH IS DESIGNED FOR WAVE SOLDERING, TO USE FOR TOUCH-UP/REWORK ? CURRENTLY ALL OUR OPERATORS HAVE LITTLE RE-FILLABLE BOTTLES AND GO AND FILL THEM UP FROM THE FLUX CONTAINERS ( I'M NOT EVEN TOO SURE WHETHER OR NO

Cleaning PCB After Soldering - How?

Which is the best way to clean the PCB after soldering? Is it good enough with IPA (isopropyl) or with the Flux Remover spray? However, we use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wet and surface g

150º de-ionized water, however, if you're doing hobby work at home, regular hot water will be fine. Just be sure to allow the water to dry sufficiently before powering up the board. You can also use IPA or a custom flux cleaning solvent available o

I only inhale flux with a high IPA content.(joke for those who don't know me) I have seen the inside of duct work for our wave soldering machine............NASTY! DAVE F. is right! Flux contains a lot of bad stuff- Chlorides, Bromides, Flourides,

THANKS FOR YOUR REPLY GUYS... more background... solder paste is Water Soluble. We mask the potentiometers prior to aqeous washing using solder mask, then our operator brush the solder joints with IPA after the Wash Process...I'm concerned about th

There is a lot of information available about cleaning no-cleans. Takes chemical, mechanical and thermal energy. Find the right chemistry for the flux (not something like IPA that will most likely just smear the residues around and cause problems

It's not acceptable to us. More importantly, you need to determine if it's acceptable to your customer. Recognize that your little IPA scrub does NOT remove the OA flux residues from the board. It mearly spreads them out across the board and under c

Dear adam Sounds to me like it may not be Salt water contamination or even flux residue's, as both of these are commonly cleaned semi aqueosly or with IPA. Have you considered it may be Talcum powder used as fillers in solder resist, mineral salts
