I have normally seen thieving added by the board house using constraints
driven by the board constraints (i.e. no floating copper areas closer than x
distance from signals, keep thieving out of specified area, etc.)  This
allows the fabricator to tailor the thieving to where and how much they
actually need.  We review the gerber files of the thievived design before
giving the authorization to build.

Subject: [DC] copper thieving


Hi,
I've been advised by the board house to add copper thieving to the outer
layers of a design we've sent them for manufacturing.  I understand they
need to add copper in bare areas to allow them to plate evenly across
the board.  We're considering a copper pour as opposed to sporatic field
oof copper squares...any suggestions, advice, comments?
Thanks for your input,
Kitty
