c0nsumer Posted August 2, 2006 Report Share Posted August 2, 2006 Hey everyone... I just took a moment to write up the steps I use to clean flux from PCBs after I assemble them. This isn't always needed, but it's generally regarded as a good idea.I do this using simple 99% isopropyl alcohol, distilled water, and a few brushes. That is, chemicals and supplies which are commonly available and not especially expensive.If you'd like to read this write-up, please look here: http://www.nuxx.net/wiki/Flux_RemovalSuggestions / comments / questions / flames?-Steve Quote Link to comment Share on other sites More sharing options...
dj_statikfire Posted August 2, 2006 Report Share Posted August 2, 2006 I use Genesolve 2004, which is so good, it's acutally illegal to manufacture! But somehow I am able to buy it every year.THX,JD Quote Link to comment Share on other sites More sharing options...

But somehow I am able to buy it every year.Looks to me like it's just a CFC / Methanol blend. (datasheet) Why not use just methanol (or isopropyl, since it's easier to obtain) instead of dumping CFCs into the atmosphere? I'd imagine straight alcohol is cheaper, too...-Steve Quote Link to comment Share on other sites More sharing options...

DrBunsen Posted August 3, 2006 Report Share Posted August 3, 2006 Hi Steve. It would be great if you could add this writeup (or a link to it) to the DocuWIKI Quote Link to comment Share on other sites More sharing options...

Believe me, that hole in the ozone layer, which sits right over Australia, you can feel that in summer.....And our weather is changing drastically every year....Dodgy.

c0nsumer Posted August 3, 2006 Author Report Share Posted August 3, 2006 Hi Steve. It would be great if you could add this writeup (or a link to it) to the DocuWIKIAh, good idea. In the amount of time it took you to make that reply you could have added the link to the wiki yourself, though.Why not just add things you find useful instead of suggesting that others do so?-Steve Quote Link to comment Share on other sites More sharing options...
c0nsumer Posted August 3, 2006 Author Report Share Posted August 3, 2006 Believe me, that hole in the ozone layer, which sits right over Australia, you can feel that in summer.....And our weather is changing drastically every year....Dodgy.Today it was 37.2°C here, with an apparant temp (after figuring in humidity) of 40.5°C. And we're at ~42.5°N latitude.It's getting fscking HOT.-Steve Quote Link to comment Share on other sites More sharing options...

Would I need to remove the ICs and PICs from the PCBs before cleaning the PCB?s... depends what you are doing. I normaly remove flux before I assemble the boards with removable items.If you remove them you're on the safer side for shure, but if you don't spoil your components side with any solvent, you don't have to worry anything.Greets, Roger Quote Link to comment Share on other sites More sharing options...
Echopraxia Posted October 5, 2007 Report Share Posted October 5, 2007 Well I used no clean solder and I am very happy with it but I bought some crappy radio shack wick which left some brown stuff on the board when I had to desolder anything. I got some better wick right away but I already made a couple modules while using the radio shack brand. The other boards look fine but still have that clear goo around the joints.

Davo Posted October 5, 2007 Report Share Posted October 5, 2007 I've been using Flux-Off from Chem-spray for cleaning my boards. It's mediocre at best. It never seems to get all the flux off. Instead it gets spread all over the board and makes it sticky. It sounds like using denatured alcohol would be a better idea. Would it be a Good Idea to submerge the board in alcohol as long as I take care to use washable switches and pots? Quote Link to comment Share on other sites More sharing options...
Twin-X Posted October 5, 2007 Report Share Posted October 5, 2007 I've been using Flux-Off from Chem-spray for cleaning my boards. It's mediocre at best. It never seems to get all the flux off. Instead it gets spread all over the board and makes it sticky. Clean your board afterwards with water. (do not solder pots on the board yet and other things that can get rusty when washing in water).
