As an EMS and supporter of board houses I think you need to be careful here.
When scoring or routing with tabs you are removing material that may allow
the panel to bow and twist all over the place. Methodical DFM should be
practiced up front.

Hi Jim
If you assemble PANELS then the bow and twist is measured on the PANELS.
If you assemble INDIVIDUAL BOARDS then the bow and twist is measured on
INDIVIDUAL BOARDS.
