2.3.4 Vacuum check
The placement process does not start unless three conditions are fulfilled: 2
– The vacuum threshold in the Keyence pressure sensor has been reached (approx. –650
mbar).
– The lifting table is "up".
– The center belt sensor is covered (photoelectric switch).
2.3.5 Deactivating the width adjustment unit
The conveyor side walls are prevented from moving together when the vacuum tooling / solenoid
valve connecting cable is plugged in. 2

2.3.6 Opticon barcode reader
Only the PCB barcode of the first substrate in the wafer boat has to be read. To guarantee this an
additional stopper is installed on the input belt. 2

2.3.7 Input belt stopper
The stopper on the input belt ensures that it is always the first barcode in the wafer boat that is
read. It extends when the barcode reader is triggered and moves back in once the barcode has
been read (see picture). 2
