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 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
