There are four global fiducial marks at:
(37mm,100mm),(37mm,460mm),(395mm,100mm),(395mm,460mm)
For reference, the coordinates of the corner pin of P6 are (36.55mm,74.94mm)
The point fiducial marks have coordinates relative to the mounting center as following:
U15: +- 900mil
U17: +- 14mm
U20: +- 18mm
U22: +- 18mm
U23: +- 22mm
U24: +- 18mm
