Ken,

If we get this type of order, we typically ask for a contact at the
assembly house.
We try to palletize/panelize based on the info that the assembler
provides (max.
pallet size, rails for clamping etc.).  We then output the solder pastes
(if asked) in the
same pallet form for the customer to take to the stencil maker.  A lot
of times, when
the board comes back in for another order or a rev spin, we will get a
mechanical
drawing that matches the initial pallet.  For some less experienced
designers, it is
easier to get the spacing and lay-up from the fab house.

Don't know if that's the info you are looking for, but if you need more
specific help,
contact me off the TechNet and I'll try to help.
