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.

Although this is possible, we do not recommend it because it can cause problems with accuracy.2

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

2.14 Position of the local component fiducials
(for two fiducials per component)
– The local component fiducials must be arranged so that all the fiducials occur either in stopper
area 1, in the area of overlap or in stopper area 2.
– The local fiducials must be in the same processing ar
ea as the placement position (center of
component).
– If only one local fiducial is used per processing area,
then it must occur in the same processing
area as the center of the component.
