Only thing we don't route between is 0402's.

Has anyone tried routing under 0603s?

Sometimes there is no choice but to either take a trace under a
component (where it will not affect or be affected by that component) or
put in awkward via's and break planes underneath etc which can often
look and perform worse.
Although we may well try not to route through/under a component
sometimes we have to see sense & ignore the whinges of the repairers
(who should only be doing this very rarely).
We can always just tell the Whinger that it was not done using a via for
EMC reasons, and because they don't know anything about it usually just
wander away grumbling :-)
Although I won't go underneath anything 0805 and below anyway.
Matthew.

Subject: [DC] Routing under vias
I'm just wondering what the general consensus is with routing under
components? In general my company has always frowned upon routing under
resistors and capacitors. I am working on a small 2 layer board and
would like to use the components as jumpers to limit the number of layer
changes for a few signals. Any thoughts?
