The PCB camera system (see item 1 and 2 in Fig. 6.1 - 5) essentially consists of the following
components: 6
– Optical lens
– CCD chip
– CCD camera amplifier
– An illumination level for illuminating PCB fiducials and ink spots
The PCB camera system is fixed to the Collect&Place head on the underside of the gantry. As
standard, it can center PCBs from 50mm x 50mm up to 460mm x 460mm (2" x 2" to 18" x 18"),
with the thickness ranging from 0.5mm to 4.5mm. 6

6.1.4 Vision analysis unit
The vision analysis unit (see item 1 and 2 in Fig. 6.1 - 6) plugs into the machine’s control unit. It
processes and analyzes the electrical signals from the component and PCB camera systems.
Corrected values are calculated from any deviations from setpoint. These values are then used to
recalculate the placement positions and rotational angle for placement. 6
The vision analysis unit also performs a component identification process. If the synthetic model
and the package form measurement do not tally, for example, the component will not be placed. 6
The precise component pick-up position, which is particularly important for small components, is
also determined in the vision analysis unit. Fiducials on the feeders are used to determine the de-
viation in position of the individual feeders. 6
The electronic image signals from components, PCB fiducials, and feeder fiducials can be trans-
ferred from the vision analysis unit, via the video multiplexer, to the station monitor, where they are
used for measuring and testing purposes. 6
