With ceramic substrates there is generally very little contrast between carrier material and the
coating on the PCB. For this reason, specific criteria regarding the shape and layout of the fidu-
cial must be taken into account when selecting the fiducials. See the following recommendations
for the shape and layout of fiducials.
)LGXFLDO6KDSH
We suggest a rectangular or square with an edge length of > 1 mm and a clearance of > 0.1 mm.
NOTE
Single crosses are also suitable, however they require more space.

Fiducial layout Black resistor paste as a background and conductor paste printed on it as a fiducial.
Recommendation Background > 1.0 mm bigger than the fiducial on all sides.
Always use printed conductor layer as a reference -> Accuracy
Generally, sufficient contrast is created with the PCB camera multicolor, except in the
case of AgPt.

NOTE
The function "Ceramic substrate centering" is activated if the optional "Mechanical ceramic sub-
strate centering unit" is installed and is entered in the machine options (activation: see Section 2.8).
With the help of this function which can be found in the fields "Processing area 1" and "Process-
ing area 2", it is possible to check the function open/close the substrate centering unit

The ceramic substrate centering unit is closed.
Å Proceed in a like manner for "Processing area 2".
For a trial run with substrate (e.g., after adjusting the substrate size) a substrate of the appropri-
ate size (as set on the substrate centering unit) is placed on the input conveyor. The steps taken
are as follows:
Å Place the substrate on the input conveyor.
Å Click on the button
