1. Size-driven mode
See Section 5.6.4.14 from Page 5 - 109 for a definition of the measuring methods.
You can recognize this measurement method by rotating windows around the component edges
Procedure:
I. Inside the search window profiles are created in the x and y directions. With the aid of the gradients thus
formed and a geometric filter the approximate position of the component is determined.
II. Windows rotate around the component’s edges. The profile and gradients are determined for each win-
dow. The sum of the gradients is an indication of the agreement of the window angle with the position of
the component.
If the sum of the gradients reaches a maximum the angular position of the component has been deter-
mined.
III. Under the angle determined in step II the first step (I) is repeated. Now it will be possible to determine the
position of the component in the x and y directions more accurately.
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.
Applies to all measurement steps!
2. The component must be located within the orange window otherwise the measurement results will
not 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 possible 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.
Cross:
white:Results of position recognition-> x and y angles
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-interpo-
lated angular position. The final results (via interpolation) are indicated a light blue line. The preci-
sion of the diagram is limited by the resolution of the monitor.
2. Row-driven mode
See Section 5.6.4.14 from Page 5 - 109 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:
I. 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.
II. With two additional windows the angular position of the component can be determined.
Rectangles:
green: x and y pick-up tolerances
light blue: A. 2 to 4 search windows for position recognition. These are positioned around the
central lead of each row of leads.
B. 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 measurement algo-
rithm has been selected the middle or the tip of the lead will be displayed.

3. Corner Driven Mode
See Section 5.6.4.14 from Page 5 - 109 for a definition of the measuring methods.
This measurement method can be recognized by the windows around the entire row of leads.
Procedure:
Determine the position in the direction of the leads in the light blue window
Determine the position vertically to this in the dark blue window
Calculate the position of each leads 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.
