7.6 PCB alignment
Item no. 00119677-xx PCB alignment for single conveyor
Item no. 00119678-xx PCB alignment for dual conveyor
7.6.1 General
PCBs to be processed sometimes have a length to width ratio of 1:2 or worse. This means that
the shorter side of the PCB points in the direction of travel. During travel, such PCBs may twist
slightly and, as a result, the fiducials no longer lie within the PCB vision camera's search window.
In this case, the "PCB alignment" option ensures that these PCBs are realigned precisely at the
stopping position.
If PCBs with recesses in the direction of travel are processed, this may result in different process-
ing positions on machines with mechanical stoppers (HS-50, S-25 HM, F5 HM) and on machines
that monitor this position with laser light barriers (X-series, HF-series, HS-60, S-27 HM). The "PCB
alignment" option ensures that the PCBs are stopped at the same position on all PCB conveyors.
The "PCB alignment" option is available for both single and dual conveyors.
