6.8 DP rotation test

6.8.1 Measurement principle

The DP rotation measurement is used to verify the DP position.

During the measurement, the calibration tool is picked up, moved to the component camera and

positioned at 4°(4000 digits). The component camera then captures a live image of the calibration

tool and checks if the position is within the allowed limits.

6.8.3 Interpretation of the results obtained

‘DP rotation angle’ error for all segments

Cause Solution

Possible contamination of component camera ► Clean the lens or replace the component

camera.

‘DP rotation angle’ error for individual segments

Cause Solution

DP does not rotate reliably ► Replace the segment (DP).

Calibration component rotates on nozzle ► Check if the nozzle is dirty and clean it if

necessary.

► Check the nozzle seat.

► Check the vacuum supply.

6.9 Dp- / Z-Positioning

6.9.1 Measurement principle

The Dp-/Z-Positioning measurement checks the deviation between the Z-axis down light barrier

and the component sensor, in accordance with the angle setting of the segment. Each segment is

moved down and moved to an angle of 0°, 60°, 120°, 180°, 240° and 300°. For each angle, the

position is determined where the nozzle interrupts the beam of the component sensor and when

the light barrier is activated.
