Kevin,
Use of non-functional lands is reccommended but not mandatory
per IPC-D-275 and Mil-STD-275. One other thing, I assumed you meant that
the design activity could remove them at their judgement and not the pwb
manufacturer. I would take great exception to a manufacturer taking it upon
himself to modify my design to simplify his process (although, in the
true spirit of DFM, CE, etc., I am always open to reasonable, cost-saving
ideas)

________________________________________________________
The design guides for MIL-STD-275 and IPC-D-275 require non-functional pads
on all layers of a multilayer PWB. Can manufacturers remove them an their
judgment?
If anyone knows the verse and script, that would be great.
Thank you in advance,
