So next time that you order boards from your fabricator, consider asking the your fab to cap these pesky via on the solder side with SR1000 [or whatever they think will be good and cheap]. Think of the money you'll save. Your boss will be ecstatic!!!

Are you concerned with physical vibration or electronic interference? If you can see your morning coffee have "rings", screen printers may suffer. Trains are a monsterous source of electrical "noise", just by thier engine (electric and diesel) not
