3.5.1.1 Description
The 12-nozzle Collect&Place head works on the Collect&Place principle. This means that, within
each cycle, twelve components are picked up by the placement head, are optically centered on
the way to the placement position and are rotated into the required placement angle. They are

then set down gently and accurately on the PCB with a blast of air. The twelve nozzles on
SIPLACE Collect&Place heads turn about a horizontal axis, in contrast to conventional chip
shooters. 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.
