Make sure the paper is advancing correctly on your stencil wiper. I have seen this cause major issues. If the paper hangs up, it will smear paste across the bottom of the stencil every time it wipes.

Rain X goes on windshields. Nano coating goes in the garbage. Order your stencils correctly from a reputable stencil house and fugetaboutit.

It seems to be no solder paste release at certain stencil opening, you may need to enlarge the stencil opening. By the way what is the area ratio for the opening and how is the shape (round/square/diamond)?

Can you use the equipment manual as the basis for learning how to use the machine? Each model of printer has different alignment techniques. We don't have a clue of your model type. So, we'll approach the question from its most basic point. Registe

When we get a very large board that's arrayed or one I think will be difficult we send a sample board. It helps our stencil manufacturer get it right. So for it has worked for us.

Your selection of pads to use as Fids will be critical. In your pictures of the QFN component, the pcb pads are primarily non-solder mask defined, but on 3 sides of the QFN the corner pads become solder mask defined due to the copper ground flood.
