All the components are inserted with the same cycle time. Before the component is inserted, it is
measured by the optoelectronic vision module. 1

The component vision camera creates an image of the current component.
The precise position of the component is also determined.
The package form of the current component is compared against the programmed package
form in order to identify it. Any components that cannot be identified are rejected.
The turning station turns the component to the required placement angle.
1.13.2 Description of the 12-segment Collect&Place head
The 12-segment Collect&Place head works using the "Collect & Place" principle, i.e. the com-
ponents are held by the nozzles with the aid of a vacuum and, after one complete pick-up cycle,
are placed gently and accurately on the PCB with the aid of blast air. The vacuum in the noz-
zles is also checked several times to determine whether the components were picked up and
set down correctly.
The "adaptive" sensor stop mode of the Z-axis compensates for any irregularity of the
PCB-surface when the components are set down.
Defective components are rejected, and are reworked during a repair cycle.
