3.6.4.1 Description
The 12 segment Collect&Place head operates according to the Collect&Place principle i.e. one
cycle includes pickup of 12 components by the placement head, their optical centering on the way
to the placement position and their rotation into the required placement angle and position. They
are then placed gently and accurately onto the PCB with a blast of air. In contrast to the conven-
tional chip shooters, the twelve nozzles of the Collect&Place heads rotate around a horizontal
axis. This not only saves space: the reduced diameter leads to a lower formation of centrifugal
forces than in chip shooters. This largely prevents any unintentional displacement of components
during transportation.
Another benefit: the Collect&Place head has the same cycle time for all components. This means
that the placement performance no longer depends on the size of the components placed.

3.7 Gantry system
The gantry system of the SIPLACE SX1/SX2/DX1/DX2 machines is a so-called H gantry. This
consists of two Y axes which are driven from both sides by linear motors. The X axis is driven by
one linear motor. The H gantry runs over a fixed and a loose bearing along the bearing surface of
the two Y axes. These surfaces are at an angle of 45° to the gantry. The linear scales for the Y
measuring system are located under these bearing surfaces. In the SIPLACE SX/DX, the gantries
have the same design. This machine can be equipped with either one or two gantries. The SI-
PLACE SX2/DX2 has gantries 1 and 2 which are fitted at an angle of 180°. The placement heads
are fitted to the inside of the gantry.
