lint from what?...also roughly how often do you clean the oven? (not the heated chamber) but other areas to keep them clean? The operator say he has had to do it twice in 2 weeks to keep it clean due to the residue

lint from the factory conditions, enviromnent you know. We clean every 6 mos. you seem to be accumulating quite rapidly. unless you are cleaning at the first spec of this showing up

I have always attributed to flux and "lint".

Have you tried running a few bare boards through the oven? If there is no flux on them and you still get the "stains" then I think you can eliminate the flux as the cuprit. And I've been told that white is the second most difficult solder mask colou

Hi SMTnetters, 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 ov

We have asked the supplier use whiter soldermask taking more heat. We also asked the board supplier to double coat board with soldermask. All these tries failed. We are wondering if the stains are flux contamination.

we didnt see it as a potential risk, main accumilations we around the entry and exit curtains so we lived with it and cleaned (quick wipe with acetone) once a week.

White solder mask does have a tendency to yellow within the lead free environment. so double coating will not help any. I due believe the flux is a factor in the yellowing but due to the color is the main reason. Find out what brand of S/M mask they

Hi, I off center idea we used when we started. Get a pasta cooker, and put in vapor phase fluid, and then use that. Place the product in the bottom of the inner pot, and then heat on a small hot plate. When the vapor cloud gets high enough and the

The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had
