We are going to try double sided reflow for the first time. Can we use the same 63/37 paste on both sides? The board also has bare copper pads i'm pretty sure. will this present any challenges? The bottom side has a QFP on it. Should it stay on?

This rule is very conservative depending on the epoxy you use and the subsequent handling of the board prior to reflow. You should use lead to pad contact area. Also be sure to look at part height and clearance on your flowsolder machine.

Not to be off-topic, but push engineering for embedded passives and remove parts from the underside all together. Watch the material cost sky rocket, but watch the manufacturing cost sink and well as improve the production cycle by 50%. Sorry, I w
