7.4.3 Description
The 6-segment Collect&Place head can optically center and place component sizes from 0.6x
0.3mm² to 13 x 13 mm² using the DCA vision module. The DCA package optimizes the speed
and accuracy when placing high-speed flip-chips and bare die components. 7

7.5 Multicolor PCB camera (type 18)
7.5.1 General
As an option, a multicolor PCB camera can be installed in place of the sub-gantry camera. The
multicolor PCB camera offers four different types of illumination. This greatly increases fiducial de-
tection and thus the centering accuracy.

7.5.2 Type of illumination
The following types of illumination can be selected on the multicolor PCB camera:
– Standard lighting
This mixture of white and infrared lighting can be used to detect a broad range of fiducials.
The image contrast can be improved by varying the illumination, thus optimizing the centering
of different fiducials.
