6.1.1 Component camera system on the revolver head
The component camera system (see item 2 in Fig. 6.1 - 2) essentially consists of the following
modules: 6
– Lens system
– CCD chip for creating an electronic image of the component
– CCD camera amplifier
– Three illumination planes - flat, medium and steep - for optimum lighting of a wide range of
component shapes
– "Illumination control" board for setting the intensity of the individual illumination planes

The component camera system is fastened to the top of the revolver head with four hexagon
socket-head screws and is fixed in position with two parallel pins. 6
The component camera system can be used to optically center and place components ranging
from 0402 up to and including SO32 in size. The components, therefore, can vary between
1.0 mm x 0.5 mm and 18.7 mm x 18.7 mm in size and from 0.3 mm to 6 mm thick. The minimum
lead pitch can be as little as 0.5 mm. 6
