8.5.3 Illumination Types
The following types of illumination can be selected on the multicolor PCB camera:
– White illumination
This illumination mode is used for standard boards with tin-plated fiducials.
– Blue oblique illumination
Used with bare fiducials on light-colored base materials, such as ceramic or CEM, this can
generally make a significant improvement to the contrast. Fiducials covered with solder resist
can also be detected better on a light background.
– Infrared illumination
This illumination mode is particularly advisable for fiducials which are covered with solder
stop varnish or for fiducials made of flex material. 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.
8.5.4 Fiducial and Ink Spot Criteria
Fiducial and ink spot criteria are described in the sections 3.12.4.3 and 3.12.4.4, page 185.
