7.5.3 Illumination Types
The following types of illumination can be selected on the multicolor PCB camera:
– White illumination
This type of illumination is used for standard PCBs with tinned fiducials.
– Blue oblique illumination
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 illumination
This type of illumination is particularly useful for fiducials that are covered with solder resist
or for fiducials on flex materials. When using silver or platinum fiducials on a ceramic base,
this type of illumination could also achieve better recognition results. This should be checked
in advance by performing a test centering/placement run.
7.5.4 Fiducials and Inkspot Criteria
Fiducial and inkspot criteria are described in section 3.13.6.3 and 3.13.6.4, page 232.

7.6 PCB Barcode Scanner
7.6.1 Overview
[ 7
The PCB barcode scanner is used to automatically record and decode barcodes on PCBs. The
PCB barcode scanner sends the read data via its serial interface to the transport controller and
then for further processing to the machine controller via the CAN bus.
