Lines: 6
red: Edges of the component detected 6
Comments: 6
The red lines may often be covered by others and thus possibly not detectable. 6
Overlay: 6
gray: Profile in the integration direction in question 6
blue: Gradients from the above profiles 6
yellow: Results from the geometric filter 6
red: Interpolation limits for position determination 6
light blue: Results of interpolation -> Position 6
Comments: 6
The results of interpolation should be found around the maximum of the geometric filter. 6
Cross: 6
white: Results of position recognition -> X and Y-angles 6
Diagram: 6
Results function of the angle search (rotating windows). 6
Comments: 6
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. 6

2. Row mode
See Section 6.6.4.14
on page 289 for a definition of the measuring methods. 6
You can recognize this measurement method by the presence of windows around the central lead
of a row of leads. 6
Procedure: 6
(1) Position recognition takes place by creating a profile vertical to the direction of the rows. 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: 6
green: X and Y- pick-up tolerances 6
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. 6
Star: 6
orange: Results of approximate search 6
Comments: 6
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. 6

3. Corner Mode 6
See Section 6.6.4.14
on page 289 for a definition of the measuring methods. 6
This measurement method can be recognized by the windows around the entire row of leads. 6
6
Procedure: 6
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

4. Lead mode 6
See Section 6.6.4.14
on page 289 for a definition of the measuring methods. 6
This measurement method can be recognized by 6
– either there being a window around a leads group (combined window, preset value)
– or there being a window around every single lead (separate window). You can modify the win-
dow types separate or combined window in the Measure mode Lead menu.
Procedure: 6
Each lead will be measured in a way similar to corner mode or the entire leads group will be mea-
sured. 6
