    Not sure if many of you are experienced with PCB design, but perhaps for someone in the industry: Are there alternatives to Board level shielding to prevent EMI from affecting other portions of a PCB design? I was thinking perhaps an EMI potting would exist but the more I think about it, physically I understand why it probably wouldn't work... I think the best solution is to pull a ground line to via's around the area where I'd like to solder a shield, but am ideally looking for more options.. Any ideas?

    Underneath you use a plane of copper. Overhead you add a metal shield. I've seen this technique used in contemporary GPS units and the like. Some shields solder on, some just seem to snap into thru holes.

    That's my short take, I don't work with devices that need such shielding.

    I've seen thousands of metal containers on circuit boards, but not one thing other than that as a shield. Just look inside your cell phone to see the state of the art today. It's a metal container.
