Integration settings
Once you have clicked on the ‘Integration settings’ field, the Row measuring mode integration settings
menu will appear on screen.

Measuring times can be reduced by lowering the resolution in the measuring or integration direction. How-
ever, you must ensure that the structure to be analysed has a sufficient number of pixels. Otherwise, the mea-
suring quality will be compromised.
5.6.4.18 ‘Corner’ measuring mode
Click on the ‘Setting’ field in the ‘Corner’ measuring mode to call up the Corner measuring mode menu.

Fig. 5.6.30 Measuring mode option, Corner measuring mode menu
This menu is used to
– specify the lead measuring method.
– select the number of leads to be measured at each corner.
– switch the angle measurement on or off.
Measurement
If the inner lead tips are mapped better that the outer tips, for example if a shiny lead is bent upwards slightly,
you can select one of the following options:
– measuring the tips via the inner tips of the leads, for bases, for example
– centre of the lead, center measurement, for PLCC, SOI, for example
– measuring the tips via the outer tips of the leads, for QFP, SOT, SO, for example
Number of leads to be measured at each corner
If the lead no longer stands out well from the background, in the case of white plugs, for example, use this
option to specify the number of leads to be measured. However, to do this, the component must be fully
described in the line computer (FDC). In this case, there are no further lead measuring steps.
NOTE
This value should only be modified for special components and plugs.

Angle measurement
For single-row components, the angle of rotation is not calculated correctly. Consequently it is better to
access calculation of the angle of rotation in Row measuring mode. Switch off the angle measurement in this
option.
5.6.4.19 ‘Lead’ measuring mode
Click on the ‘Setting’ field in the ‘Lead’ measuring mode to call up the Lead measuring mode menu.

This menu is used to
– specify the lead measuring method.
– to select the windows separately for each lead or a combined window for every lead to be measured.
