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 also be
placed right up to the edge.
7.5.2.2 Assembling and dismantling the ceramic substrate centering unit
PLEASE NOTE 7
The ceramic substrate centering unit must only be assembled and dismantled by service engi-
neers. 7
