Subject: Re: Capping vias for BGA's


On a board that gets bga components and sees wave solder,
it is probably advisable to plug the vias from the wave
side of the board (usually opposite of the bga component
side) to prevent solder from the wave process wicking
up the vias and causing shorts under the bga
component.
