Thanks Harry,
I sort of remember that now. Wasn't there an alternate location
(yahoo group of some sort) that allowed for doing such things. I know I've
seen posts that mention board example pictures.
Regarding the older standard, I had copied that from one of our
former layout people before all of that was outsourced. I doubt I could get
them to spring for a copy of the new standard for those of us here who are
doing prototyping. Oh well.

everything doesn't happen all at once.

Hi Dan,
Attachments aren't allowed on posts to this forum - they get filtered
out. You would have to post a link to a file, or send it offline to
whomever you wished to receive it.
IPC-D-275 has been superceded by IPC-2221A. Section 6.3 of
IPC-2221A, Generic Standard on Printed Board Design, has the voltage
clearance calculations for various configurations of rigid circuit boards.
