7.4.3 Position of the Stationary Component Cameras
The position of the stationary component camera and the corresponding configuration are de-
scribed in section 3.13.1
, from page 224 onwards.
7.4.4 Safety Instructions for the TwinHead Component Cameras during
a Placement Head Change
WARNING 7
During a placement head change from TwinHead to Collect&Place CA head, the component
cameras (stationary P&P, type 33, 55 x 45, and type 25, 16 x 16) for the TwinHead must be dis-
mantled, otherwise the Collect&Place CA head will collide with the camera housings.

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.
