DFMRULES array

MATRIX Array Level: 1

Assigns PCB Manufacturing Rules and Constraints.
Includes 300+ of the Most Common and Popular DFM Checks!

Note
DFM Rules are separated into 3 Constraint Sets:

DFF (Design for Fabrication)
DFA (Design for Assembly)
DFT (Design for Test)

<DfmRules name="4 Layers Standard" units="mm"></DfmRules>

Fields in the DFMRULES array
