Our Manufacturing facility requests 20 mil pad to pad for reflow and 40 mil
pad to pad for solder wave.
Hope it helps.

I've tired to find out how much clearance is required between SMD parts
such as 0603, 0805, and
SOT23 parts.  For example, if I have 2 0603 resistors side by side, what's
the minimum distance
between the resistors?  Are there rules of thumb or IPC rules?  How
accurately can SMD parts be
placed by machine?  I've asked an assembly house, but didn't get an answer.
I'm looking for typical
values.
