6.1.3 Vision analysis units
The two vision analysis units (see items 1 and 2 in Fig. 6.1 - 4) are plugged into the placement
system’s control unit. 6
They process and analyze electrical signals from the component and PCB camera systems. Cor-
rection values are calculated from any deviations from setpoint. These values are then used for
recalculating the placement positions and angle of rotation for placement. 6
The vision analysis units also perform a component identification process. The precise component
pick-up position, which is particularly important for small components, is also determined in the
vision analysis units. 6

The electronic image signals from components, PCB fiducials and feeder module fiducials can be
transferred from the vision analysis units via the video multiplexer to the two station monitors,
where they are used for measuring and testing purposes. 6
