Rectangles:
green: x and y pick-up tolerances
orange: component dimensions and tolerances supplied by the station
blue: search area for position recognition
Comments
1. The position of the component as determined must be within the green rectangle
otherwise the component will not be placed.

2. The component must be located within the orange window. Otherwise the measurement
results will not be dependable.
3. The search areas should have the same alignment as the component and also be larger
than the component.
Lines:
red: Edges of the component detected
Comments:
The red lines may often be covered by others and thus possibly not detectable.
Overlay:
gray: Profile in the integration direction in question
blue: Gradients from the above profiles
yellow: Results from the geometric filter
red: Interpolation limits for position determination
light blue: Results of interpolation-> Position
Comments:
The results of interpolation should be found around the maximum of the geometric filter.

Diagram:
Results function of the angle search (rotating windows).
Comments:
The minimum (corresponds to the maximum of the sum of the gradients) indicates the non-
interpolated angular position. The final results (via interpolation) are indicated by a light blue
line. The precision of the diagram is limited by the resolution of the monitor.
2. Row-driven mode
See Section 6.6.4.14 on page 6 - 281 for a definition of the measuring methods.
You can recognize this measurement method by the presence of windows around the central lead
of a row of leads.
Procedure:
(1) Position recognition takes place by creating a profile vertical to the direction of the leads. In
this way the edges of the component are determined.
(2) With two additional windows the angular position of the component can be determined.
Rectangles:
green: x and y pick-up tolerances
light blue: $ 2 to 4 search windows for position recognition. These are positioned
around the central lead of each row of leads.
% 2 additional search windows for angular measurement. The two
windows are located on the same row of leads.
Star:
orange: Results of approximate search
Comments:
The star indicates the position in the direction of the leads. Depending on which measure-
ment algorithm has been selected the middle or the tip of the lead will be displayed.

See Section 6.6.4.14 on page 6 - 281 for a definition of the measuring methods.
This measurement method can be recognized by the windows around the entire row of leads.
Procedure:
Å Determine the position in the direction of the leads in the light blue window
Å Determine the position vertically to this in the dark blue window
Å Calculate the position of each lead group and thus of the component
Rectangles:
light blue: Search window for the position in the direction of the leads
dark blue: Search window for the position vertically to this
green: x and y tolerances
Star:
orange: Results: Location of the group in question
Comments:
Depending on which measurement algorithm was selected the middle or the end of the lead
group in the direction of the leads will be shown.
