6.3 PCB alignment
Item no. 00119425-xx Mechanical PCB alignment for dual lane D4i
Item no. 00119426-xx Mechanical PCB alignment for single lane D4i
6.3.1 Description
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 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 that monitor this position with laser light barriers (X-series, D-series).
The "PCB alignment" option ensures that the PCBs are stopped at the required position on the
PCB conveyors. The "PCB alignment" option is available for both single and dual conveyors.
