It really depends on pad design and other component on the PCB. Most of the time I run 0201s I have microBGAs on the board and usually print 3mil. Reduction will depend on the paste. For leaded paste you will have reduction (about 10% or so).For Lea

0.8m/min is a different story. I run my 10 zone reflow ovens with that speed all the time and never had a problem. For the short profile I mentioned the speed I used is even higher(about 1.25m/min). No issues with parts moving. Regards, Emil

Is this fluxed / solder paste or flux-less reflow process? Are you soldering in a nitrogen or vacuum oven? From my experience having gold-tin connections go through reflow a 2nd time does not yield defects or quality issues. However, I cannot comm

Sounds like all the usual suspects have been replaced. How about some completely random thoughts. For this specific product, you mention it runs a few boards then fails out. Does it fail out on one specific fiducial on this product every time or i

Per IPC-A-610D: Target is 100% vertical fill but 75% vertical fill is acceptable for Class 1,2,3. Only needing 75% fill of the barrel when soldering plate through on an 0.093" thick board with our selective solder has been a life saver at times.
