You might try checking to see if the float switches are actually lifting up with the water level, I have seen them get stuck in the open position. Also check to see that the solenoid valve is actually sealing off (closed)

Russ, Try to shake the 1 gallon jug and see if you can create foam on top of the liquid. If you don’t see any foam at all something is wrong with the flux. Patrick

I have a vision problem because the cam is seeing blurry, but if i manually lift the board it's starting to see more clearly, how could i fix this focus problem?

Two pictures. Dark circles around solder joints. leaded solder, water soluble flux, selective soldering and seeing these dark lines circling around solder joints. Can not remove this either. Any idea what is making this occur??? See attached photos

Dek265 Upward vision is dim. Replaced bulb. Vision is still to dark to see anything. Bottom you can see fine. Any ideas?

Thank you for that, I see the #106 nozzle looks in better shape (with the rubber) I might try that nozzle and see how it goes on a few boards, then I could let the "higher authority" know.

Seems really excessive. I am not familiar with that particular oven, but I would check to see that the fans are not seeing excess heat during use. Is there any ducting around the fans that might have leaky joints? Is there insulation around the fan

Just thought it may be helpful, my FREE 100 page ebook on Pin In Hole Intrusive reflow is available to download see http://pihrtechnology.com/ Also my book on Package on Package may also be useful for the future see http://www.packageonpackagebook.c

Would be nice to see your profile, as I would imagine you could be too cool in reflow especially if seeing milky residues in Paste could be Organics that havent volatised out properly

Thanks for the info. Have you had any experience with multi-pitch BGAS. We are starting to see more BGAs with non-standard ball pitch. See attached.
