7.6.1 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.

7.6.2 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.
– White lighting
This type of illumination is used for standard PCBs with tinned fiducials.
– Blue oblique lighting
In most cases, this can be used to greatly improve the contrast with bright fiducials on a light
base material, such as ceramic or CEM. Fiducials covered with solder resist can also be de-
tected better on a light background.
– Infrared lighting
This type of illumination is particularly useful for fiducials that are covered with solder resist
or for fiducials on flex materials. It is also sometimes possible to improve detection of silver/
platinum fiducials on ceramic. This should be tested by carrying out a test centering or place-
ment run.
