Jack,

Clearance is dictated by the Nozzle Size of the select solder machine. We
use Nozzle Size +3mm diameter as a clearance rule. For most products we end
up with a 11mm (0.433") keepout diameter ... we did at times violate but
only with smt components that could be glued and not damaged by being
subjected to secondary select solder.

hth,
Dave
