Attached is one more profile we have tried with high reflow time. The issue with before and this profile is reduced a lot. But not eliminated.

Hi Sweetoldbob, Thanks. We are using SMQ92J solder paste ( Sn63/Pb37 ). We are on higher side of reflow time for leaded paste. Regards, Ameen

I've worked with these quite a bit in the past as well. As the previous poster mentioned, we ran either 4/5 mil thick stencil with a pretty standard RTS profile in a 10 zone convention oven without issue.

Do Proper underneath stencil cleaning. if the cleaning not effective, check Vaccuum section of the printer machine. Else change the Wipe roll. Trying out with other cleaning solvent (dedicated to stencil cleaner) also improve this issues.

Probably need more info on the PCB and why baking before reflow processing is part of your process, but if you're baking before reflow it makes sense you'd bake before rework. Is there a reason you don't AOI before wash?

Is there a reason the PCBA needs to be cleaned to inspect through AOI? I AOI thousands of "dirty" boards a day without an issue.
