pends on the maximum standard placement area and the stopper offset set for the machine.
The fiducial positions should be selected on the basis of the machine with the smallest area of
overlap on the line.

2.13.3 Sample description with 3 fiducials, 2 for each placement area
– From station SW 503 and LC 503 or SIPLACE Pro 1.4
– One set of fiducials with 2 PCB fiducial
s for each processing area.
In this case, the PCB skew is ignored.

2.13.4 Sample description with 3 fiducials in the area of overlap
– From software version 502 onwards, only one set of fiducials is possible in the area of overlap.
– One fiducial set in the overlap area.

Although this is possible, we do not recommend it because it can cause problems with accuracy.
The PCB skew outside the area of overlap is interpolated. 2
