8.5.3 Throughput Test for Vacuum-Holding Circuit
Through the installation of the placement head, the silicon tube for supplying the holding circuit with
vacuum can become jammed, especially in HF/X/D3 machines.
The lower throughput reduces the holding force for the components during the placement process. This
means that components can be displaced on the nozzle, both before and after the component camera.
If this happens before the camera, the component may be moved out of the pickup tolerance. After the
camera, displacement can lead to random, uncorrectable placement offsets.
This fault can be recognized with the SITEST 'throughput test".
C&P12/6
Perform the following steps:
X Return all C&P head nozzles.
X Measure the holding circuit vacuum. Typical values are around 900 mbar (values over 900 are
shown as 900).
X Open a segment in the reject circuit and
X step the star one position.
X Measure the holding circuit vacuum. Values higher than 800 mbar are OK.
X Open another segment in the reject circuit and
X step the star one position.
X Measure the holding circuit vacuum. Values higher than 700 mbar are OK.
Values around 600 mbar are reached at around half the diameter of the silicon supply tube.
Vacuum values in the holding circuit which only reach 500 mbar are no longer sufficient to guarantee the
holding circuit function. (Values under 400 mbar are only shown as -1)

All the settings described in this chapter are head-specific and apply here for the C&P12.
8.6.1.1 8-Fold DIP Switch of the Gantry Head Distributor (incl. Switch S1) – C&P6/12
Switches P0 and P1:
Switch S1:
ON – Test mode (without delay)
OFF – Default state (with delay of 3.6 ms+/- 300 us) means: Z-axis moves downwards, the top LB
is released and the LB down is enabled after a delay of 3.6 ms.
