7.5 Ceramic substrate centering
7.5.1 General
The ceramic substrate can be centered either mechanically or optically.
The position of the fiducials on the ceramic substrates can be detected either with
– the sub-gantry PCB camera with normal lighting that is fitted as standard, or
– using the multi-color PCB camera (option).

7.5.2 Mechanical centering
7.5.2.1 General
Mechanical substrate centering is used to lock ceramic substrates firmly in position in the X and
Y directions in such a way that the material is not damaged. Ceramic substrates can be placed
right up to the edge.
7.5.2.2 Assembling and dismantling the ceramic substrate centering unit
PLEASE NOTE
The ceramic substrate centering unit must only be assembled and dismantled by service engi-
neers. 7
