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.

4. Lead-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
either there being a window around a leads group (combined window, preset value)
or there being a window around every single lead (separate window). By entering the hex code you can
modify the window types separate or combined window in the Measure mode menu.
Procedure:
Each lead will be measured in a way similar to corner-driven mode or the entire leads group will be measured.
Rectangles:
dark blue: search window around the entire leads group or around every
light blue: search window around the first lead in a group
green: x and y tolerances
Cross:
white: Results of position recognition-> x and y angles
Overlay:
gray: Profile in the integration direction in question
blue: Gradients from the above profiles
The gradients are only required and displayed for the profiles in the direction
of the leads.
yellow: Results from the geometric filter
red: Interpolation limits for position determination
light blue: Results of interpolation-> Position
Comments:
An overlay is available for both directions of interpolation.

The crosshairs indicate the position of the component in the camera coordinates system. The outline of the
component will be emphasized by the use of color.
The measured values represent geometric component parameters such as
Position in the camera coordinates system
Rotation angle

1. Grid-driven mode
See Section 5.6.4.14 from Page 5 - 109 for a definition of the measuring methods.
Grid-driven mode works with preset pattern tolerances and is therefore to be regarded as the first measure-
ment step in the optical surveying of BGAs and flip-chips. To ascertain the approximate position it will be ade-
quate to measure just a few connections.
The number of balls to be measured and the pattern tolerances define the size of the search window. The
rough position and the skew of the component are determined in corners mode - in other words, a search win-
dow size is defined for each corner of the component. This measurement method can be identified
by the synthetic model being shown in pixel resolution at the lefthand edge of the video image, and
by the 4 windows at the corners of the component.
Procedure:
The algorithm defines 4 dark blue corner windows on the basis of the pattern tolerances and the balls
defined in the package form file. The default search value is 5 balls.
A detection algorithm runs with the aim of detecting all balls corresponding to this type. Those found will be
marked with light blue crosses.
The balls defined in the package form file are determined by the search algorithm. The balls found are
marked with a white outline. If defined balls are not found an error message will appear on the screen.
From these data the rough position and the skew of the component are determined. The measured posi-
tion of the component is marked with white crosshairs.

the number of balls
