QFN Rework

SMTnetters:

Does anyone have experience in the average programming time that they use for calculating costs on using a solder dispense and place process for QFN rework? How about average cycle time from start to finish for same?

We are comparing it to our times for QFN rework using the stencil print on board method (30 minutes)and part bumping (12 minutes). All QFN rework methods presume use of a plsit vision rework system.

Thanks
