Update - next run started out horribly so went to another stencil design. Reduced thermal pad coverage by about 40% with 4 panes, with cutouts to avoid the vias. Worked like a charm for 10 boards (90 parts). I think we're finally on to something.

Hi: If anyone have the experience with the PCB pad design and stencil design for the uBGA? We meet the problem for it. The component data is 0.3mm diameter and 0.5 pitch. Could anyone tell me the PCB pad dimension, the stencil type and aperture dimes
