. Solder Mask Covered: a pad or via (via tenting) is covered with solder mask. Mask Plugged Via: for this specific measures are taken to ensure the via is plugged and sealed with mask and the annular ring is covered

Overview The conformal coating process has evolved greatly from the days of hand masking electronic assemblies and placing them into high pressure spray booths and dip tanks to apply liquid coatings. Machine developments have provided the ability to use

. I always "Flood Over" every via in a PCB layout expect those that are via-in-pad will have a thermal relief. The via-in-pad vias have to be specially marked on the fabrication drawing as they need to be plated, plugged, capped, surface finish and planerized flat so that you cannot tell if there is a hole or not

. I would go for the via-in-pad with plugged via. You can see where the Rounded Rectangle pad shape passes DRC clearance checks. Cap the via-in-pad with surface finish, planerize flat
