3.7.8.2 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.
