| | | Gian | | | | | | You alarm me when you talk of white residues in a "no-clean" process. This should not happen. It sounds like you have compatibility problems between different residues and/or a poorly polymerised solder mask. | | | | | | Ther

we are using heareous F381, F352 no clean solder paste. specially in qfp for high frequency board we observe that cleaing / removing of ' no clean flux 'is require. if we do not clean same most of time after all test & envioumental test it shows pin

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic ac

Does anyone have wave solder experience using OSP and VOC free no clean flux?

if two boards with different solder masks give different results on flux residue level after soldering with the exact same machine settings than it is clear that one of the solder masks is not compatible with your no-clean flux. could be the solder m

Tell the board shop to increase the cure temp of the resist as it is undecured especially if you have waxy/greasy resiues on the board and a brown tar like substence in the solder wave itself. If undercured then solder will not flow off the resist pr
