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

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. 6
The measured values represent geometric component parameters such as 6
– position in the camera coordinates system
– rotation angle
– maximum offset of the balls in X and Y-directions
– factor for the quality of measurement

1. Grid mode 6
See Section 6.6.4.14
on page 289 for a definition of the measuring methods. 6
Grid mode works with preset pattern tolerances and is therefore to be regarded as the first mea-
surement step in the optical surveying of BGAs and flip-chips. To ascertain the approximate posi-
tion it will be adequate to measure just a few connections. 6
