Adam,
What really counts is your assembly house and of course the mechanical
restraints of the enclosure that the board resides in.
We design on mostly PCMCIA form factor, components are a minimum of  1,27mm
(although we break this rule ocassionally). 99% of our production is panelized
and on the ones that are scored for separation the same rules apply only from
the edge of the score.

Have fun, keep smiling!

What do you guys use as a std,rule of thumb package keepin from the edge of
a PCB. We are using 1.5mm as standard but I have (the usual story) a small
PCB with alot of components to get on! Any feedback from other designers and
fabricators would be greatly appreciated.
