Thanks to those who have shared their experience/knowledge.
I have had several replies to my above stated inquiry but no definite
targeted IPC STD. I will continue waiting for that magic answer.

Somewhere in the fabrication rules within the IPC specs is a .050"
minimum requirement from all unfinished edges.
This is to prevent exposed copper smears during routing of the PCB.

Rule was a .010" sealed edge distance - I believe this comes from a
defunct MIL Spec - but I cannot recall the document #. Also - this is
after the processing tolerances of the Fab house - you must add these to
the .010" design rule.

Fellow TechNetters
Where can I locate a related guideline of how close a copper plane
and/or trace can come to the router edge of a PWB.
