then set down gently and accurately on the PCB with a blast of air. The twelve nozzles on SI-
PLACE Collect&Place heads turn about a horizontal axis, in contrast to conventional chip shoot-
ers. This does not simply save space: the small diameter means that substantially smaller
centrifugal forces occur in comparison to conventional chip shooters. This largely eliminates the
risk of components slipping during transportation.
And there is yet another benefit: the cycle time of the Collect&Place head is the same for all com-
ponents, which means that the placement rate is not dependent on the component size.

3.5.1.3 Operation with a vacuum pump
The 12-segment Collect&Place head can be converted for operation with a vacuum pump for
more efficient vacuum generation (see Section 6.12
, page 245).
