6.13.3 Interpretation of the results obtained

‘Sensor calibration’ and/or ‘Spring preload’ error

Cause Solution

Force measuring unit defective ► Adjust the force sensor unit (Q1/2018).

► Replace the force measuring and/or the trick and

feather unit (Q1/2018).

► Replace the P&P module.

► Send the P&P module to ASM for customer specific re-

pair.

6.14 Head endurance run 01005

6.14.1 Measurement principle

The Head endurance run 01005 measurement checks the reliability of the Z-axis and the DPs, es-

pecially for small components, such as 0201 or 01005, which are typically processed using the

contactless placement function.

During the measurement of the Z-axis, each segment is moved up and down a number times to de-

termine the characteristics during the upward and downward movement. Before each downward

movement, the DP is turned by 180° with the time measured it takes to reach the final position.

1 Measured Segment

2 Total number of cycles performed

3 Values from the difference between Zminpick and Zmaxpick:

Zdowndeltapick = Zmaxpick – Zminpick

4 Values from the difference between Zminplace and Zmaxplace:

Zdowndeltaplace = Zmaxplace – Zminplace

5 MinDPtime shows the value for the minimum time the DP needs to turn from 0° to 180°.

6 MaxDPtime shows the value for the maximum time the DP needs to turn from 180° to 0°.

7 #OK shows the number of successful Z-axis movements (up and down).

8 #errors…0 shows the number of failed Z-axis movements (up and down).

9 Result view indicating if the values are within (green tick) or outside (red cross) the limits.

10 #moves shows the number of performed Z-axis movements (in this case 30x down + 30x

up = 60).
