3.6.4.2 PCB warpage during placement
A warpage of 2 mm can lead to problems focussing 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.
