7.3.2 Safety instructions for the TwinHead component cameras during
a placement head change
WARNING 7
When the placement head is changed from the TwinHead to the Collect&Place head, the Twin-
Head's component cameras (stationary, P&P, type 33, 55 x 45, and type 25, 16 x 16) must be
removed, otherwise the Collect&Place head will collide with the camera housings.

7.4.3 Type of illumination
The following types of illumination can be selected on the multicolor PCB camera:
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.
7.4.4 Fiducial and ink spot criteria
The fiducials and ink spot criteria are described in sections 3.11.5.3 and 3.11.5.4, page 162.
