The component camera system is fixed to the top of the Collect&Place head using four hexagon
socket-head screws. It is then held in place by two parallel pins. 6
The component camera system can be used to optically center and place flip-chips, bare dies, and
components up to 13mm x 13mm in size. The components therefore vary in size between 0.5 mm
x 0.25mm and 13mm x 13mm, and from 0.3mm to 8.5mm thick. The minimum lead pitch can be
as little as 0.2mm. 6
6.1.4 Component camera system for the Pick&Place head
The component camera system (see item 2 in Fig. 6.1 - 5) essentially consists of the following
modules: 6
– Optical lens
– CCD chip for creating an electronic image of the component
– 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
