We have a very expensive MRP system that can (allegedly) do this, so naturally we also use an excel spreadsheet, which includes feeder loading times, 1st off inspection, printer set up, overhead recovery, machine time etc.

We make a custom mini stencil to print the paste onto the QFN and flip over to load on the rework station. The mini-stencil was designed for SRT to pick up the QFN. Check BeamOn (stencil house) for detail. Good luck

This should be the Ultraclean II H2O that Electrovert had made by Tooltronics. If so, I may be able to get a manual from 1989 machine.

Make sure your matrix tray is up high enough. The components in the matrix tray should be at least at board level. Also check your component height in the package list. If all that is OK then, check those Z locks I spoke of earlier.
