– 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 position.
3.9.2 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 forced 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 sur-
face when the components are set down.
– Defective components are rejected and are picked up again during a repair run.

3.9.5 Description of the 6-segment Collect&Place head
The functionality of the 6-segment revolver head is similar to that of the 12-segment revolver
head. With its standard vision module, the 6-segment Collect&Place head can quickly and accu-
rately place ICs with an edge length of up to 32 x 32 mm². It really comes into its own when there
is a very high proportion of ICs in the placement process. The cycle time of the 6-segment Col-
lect&Place head depends on the dimensions and number of component leads or bumps. 3
