– CCD camera amplifier
– Three illumination levels – flat, average and steep – for optimum illumination of a wide
range of component shapes
– “Illumination control” board for setting the intensity of the individual illumination levels.

The fine pitch vision module is fixed to the machine base on the right of the PCB conveyor. 6
The component camera system can be used to optically center and place components up to and
including 55mm x 55mm in size. The minimum lead pitch can be as little as 0.4mm. A flip-chip
vision module can be fitted in addition to the fine pitch vision module as an option, in order to op-
tically center components up to 20mm x 20mm in size. The minimum lead pitch can be as little as
0.25mm. 6

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 revolver 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
