We have a PCB that needs to remain as flat as when it left the fab,
but it is bolted down to a metal base. We think the base is not flat
enough. Before we call in a mechanical consultant, do you guys and
gals think it makes sense to put a pattern of concentric rings on the
PCB and then check for fringing with a lens?
I just got the Edmund optics catalog in the mail, so I got to
wondering.
