Stacking PCBs

[soldersqueeze]

 Is there a best practice for cramming pcbs in an enclosure one on top of the other? I am considering making a little platform to put between the two such as this-



I figured an earthed layer between the two could only be a good thing, but I don't know that I won't be tripping myself up by causing an earth loop or something else I don't really understand. I'd really like to hear from someone who knows more than me (ie; anyone )

That looks like a good solution right there. Maybe the best thing to do is chassis ground it? So, rather than connecting it to common ground with the two PCBs, run the ground wire from the copper plate to an o-ring which fits over the 3PDT shaft.
