Our fab vendor refuses to plug any via greater than .015". The most common
problem we see with plugged vias is excess height causing screen printing
problems. We also see solder balls forming on the top side of the board when
the bottom side is reflowed. Our vendor attributes this to the plugged vias.
Needless to say we're making every attempt to do away with the plugs
whenever possible.
