RE>Capping vias for BGA's                    11/6/96

Who recommends this?

We've never capped our BGA vias (either side) and haven't had any problems.

Hello,

My questions has to do with the capping of vias for BGA's.

Why is it recommended that vias be covered on the component side of
BGA boards ?

What are the implications of not following this recommendation ?

Thanks in advance for your input.
