I am currently building boards which have to be conformal coated (done by an outside source) in a no clean process. The conformal coating however, must be applied to a clean surface. The flux residue left from the paste has come into question. I h

Hi...i have a question. After you solder a circuit board, what do you wash the flux residue off with? I am hesitant to use water for fear of subsequent corrosion, and have no clue as to what kind of flux is in my solder wire. automated pcb assembly

On the flux reside issue that is gumming up your test probe pogos ... Short term, clean what's in process with a aerosol flux cleaner solvent. Ask your flux supplier for recommendations. Longer term, recognizing that there is no fix, your improveme

No clean is giving us problem in ICT. Other than that, a coating of flux should remain there to pretect the solder joint from the environment. In general you should not clean NO clean - it is supposed to be there.

My company currently uses water soluble paste for our SMT process. We were having trouble retaining hot water in our in line, closed loop DI cleaner. The cleaner kept shutting down when the water temp. dropped below 125C. As a result, the conveyor

For low volume hand assembly, deionized water or IPA should work fine.

regarding dwl comment, "For low volume hand assembly, deionized water or IPA should work fine." Deionized water: Deionized water is corrosive. It needs to be removed. Proof? Drop a copper coin into a covered jar of DI water and watch what happens ov

IPA and DI water are both very common and effective methods of cleaning PCBAs. http://www.zestron.com/sa/cleaning-applications/smt-electronic-cleaning/pcba-cleaning/aqueous-cleaning.html http://blog.gotopac.com/2010/11/18/ipa-as-a-universal-cleaner

Have an older reflow oven which I need to clean up collected flux residues from the chain, mesh, intake/exhaust areas, slides etc heavy brown dust, likely water soluble residues, lots of polymerized brown resin as well.
