NOTICE
Position of sprocket wheel
The absolute position of the sprocket wheel will then be measured against the feeder adapter. This might cause
an additional offset (up to 100µm in transport direction and up to 200µm across transport direction), so that the
measurement can exceed the tolerance corner (see chapter 5.2.3.1 "measurement result out of tolerance). Some
of dots are then outside the orange lines.
The feeder however might still be suitable to use (e.g. for chips >= 0805), as long as the repeatability is still good
(measurements are within the blue tolerance lines).
