There must be at least 3 Fiducials for each PCB side containing SMD
If SMDs are on both sides of PCB then fiducials are required on both sides
Fiducials must be on EACH PCB that is in a Panel
Fiducials must be at least 7.0mm from the outside edge of tooling strips
Fiducials are normally a 1.00 mm diameter solid round exposed metal pad with a 1.0mm soldermask pullback
Localised fiducials on fine pitched components (< 0.50 mm) is recommended
