3.14.4.2 PCB-Warpage during Placement
In case of a warpage of 0,5 mm problems can occur during focusing of local fiducials and inkdots
in the PCB-center. The digital camera's focus is 2 mm. When all the tolerances are taken into ac-
count, this value is reduced to 1.5 mm. Also note that the component height is reduced by the war-
page.
