Hi Technetters,
I have a white residue coating all over my reflow oven innards (almost looks like white fungus). How can I absolutely be certain that it's flux and not anything else?are there any tests available for this? I am planning to check the oven exhaust for correct air flow rates.....anything else I should be looking out for?. We are using a water soluble halide free flux and SnPb solder
Thanks in advance
