1.13.11 Description of the 6-segment Collect&Place head with DCA option
With the DCA vision module, the 6-segment Collect&Place head is able to optically center and
place components of the order of magnitude of 0.5mm x 0.25mm to 13mm x 13mm. The DCA
package optimizes the speed and accuracy when placing high-speed flip-chips and bare die
components. 1

1.14 Overview of the modules - vision systems
Every machine has 1
– a PCB vision module on the Collect&Place head,
– a fine-pitch component vision module on the machine base, and
– a PCB vision module on the underside of the X-axis gantry
1
The vision evaluation unit is located on the machine’s control unit. The component vision module
is used to 1
– determine the precise position of the component at the nozzle, and
– the geometry of the package form.
1
The PCB vision module uses fiducials on the PCB to determine 1
– the position of the PCB,
– its rotational angle,
– and the PCB distortion.
Damaged PCBs or subpanels are marked with ink spots. The PCB vision module scans the ink
spots, and signals that these circuits should not be placed. 1
The PCB vision module also uses fiducials on the feeders to determine the precise component
pick-up position. This is particularly important for tiny components. 1
