Kitty,

The requirements you are looking for should be in the manual of the machine 
that is being used. We have looked at the keep-out areas that are specified 
for the specific machines that we use.

The keep-outs may not be as plain as "keep components out of this area" they 
may show a graphic of the placement head and you may need to create a 
keepout from that. If the machine is for through hole components there will 
be a keepout for the bottom side of the board also.

Ask manufacturing for the manuals that they are getting the keepout areas 
from and check it out for yourself. If they aren't getting them from a 
manual, ask them for the manual that has the machines "general 
specifications". Our radial machine has a separate manual just for 
specifications.

Good luck
