6.1.2 Steps when picking up and placing components
– A PCB moves into the placement area of the PCB conveyor.
– After the fiducial measurement with both gantries for each placement area (with SW505), the
C&P head picks up components from the feeder moduls.
– The components are measured below the component camera and turned in the Dp station into
the correct angle position.
– In the star station 1 the component will be place.

Star station 1 6
Pick-up cycle
The nozzle is lowered onto the component. Once the valve positioning unit has opened the vac-
uum circuit to the nozzle, the nozzle draws up the component and removes it from the feeder mod-
ule.
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 burst of com-
pressed air detaches the component from the nozzle and places it on the PCB.
Reject cycle
After the gantry reach the X- and Y-reject position the valve positioning unit closes the vacuum
channel to the nozzle. Defective components are detached from the nozzle with a short burst of
compressed air and are discarded.
Star station 7 6
The component is optically centered. 6
Star station 9 6
Pick-up cycle 6
The nozzle is rotated to the pick-up position. 6
Placement cycle
The component is rotated to the placement position (angle of rotation).
Star station 10 6
The SW move nozzles and sleeves to here for checking. 6
between Star station 11&12 6
Option on 12 nozzle head:
The component height is optically checked before placement.
