To whom this may concern, I recently ran into the problem with vias on pads of BGA when place BGA and reflow gas trap on vias escape and result in ball having void greater than 50% of BGA diameter. The BGA pad is measured at 20 mils and the vias mea

We baked the board first and print 2 mil water soluble paste at the BGA location and reflow. Wash and baked before the production run.
