3.7.7.2 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.
