3.10 Vision modules
Each placement system has 3
– one component vision module on the Collect&Place head,
– one fine-pitch vision module on the machine frame and
– one PCB vision module on the underside of the X axis gantry.
3
The vision analysis unit is located in the control unit for the placement system. The component
vision module is used to determine: 3
– the precise position of the components at the nozzle and
– the geometry of the package form.
3
The PCB vision module uses fiducials on the PCBs to determine: 3
– the position of the PCB,
– its rotation angle
– and the PCB skew.
Defective PCBs or subpanels will be marked with ink spots. The PCB vision module scans the
ink spots and signals that these circuits shall not be assembled. 3
The PCB vision module also uses fiducials on the feeders to determine the exact pick-up position
of components. This is particularly important for small components. 3

3.11 PCB single conveyor
3.11.1 Structure
The placement system is supplied with a single conveyor as standard. A dual conveyor is avail-
able as an option. The left or the right side of the PCB conveyor can be used as the stationary
side, as required. 3
