3.7.7.2 PCB warpage during placement
A warpage of 2 mm can lead to problems focusing on local fiducials and ink spots in the middle of
the PCB. The digital camera's focus is 2 mm. When all the tolerances are taken into account, this
value is reduced to 1.5 mm. Also note that the component height is reduced by the warpage.

PCB warpage down, max. 0.5 mm

→ Use magnetic pin supports to achieve this value.
