Star station 1
Pickup cycle
The nozzle is lowered onto the component. Once the valve positioning unit has opened the vacuum
circuit to the nozzle, the nozzle draws up the component and removes it from the feeder module.
Placement cycle
The nozzle, together with the component, is lowered onto the PCB that has been moved into place.
The valve positioning unit closes the vacuum channel to the nozzle. A short blast of compressed air
detaches the component from the nozzle and places it on the PCB.
NOTE:
The standard camera on the C&P12 is the 28.sst, although the component camera 29.sst, with
a higher resolution (for small 0201 components), can be installed as an option.

Star station 3
Reject cycle
After the gantry reaches the X and Y reject position, the valve positioning unit closes the vacuum
channel to the nozzle. Defective components are rejected from the nozzle with a short blast of
compressed air and are discarded.
Star station 7
The component is optically centered.
Star station 9
Pickup cycle
The nozzle is rotated to the pickup position.
Placement cycle
The component is rotated to the placement position (angle of rotation).
Star station 10
Sleeves can be removed here for maintenance and then reinserted.
Between star station 11&12
Option on 12 nozzle head: The presence and/or height of the component is checked before
placement.
