This menu is used to select the

– integration direction,

– the resolution in the measuring direction and

– the resolution in the integration direction.

Integration direction

In order to determine the angle, select the integration direction towards either the X or Y axis of the compo-

nent. We recommend that you select the longer edge.

Resolution in the measuring direction

Select this resolution in order to optimize the measuring times at the revolver head.

Resolution in the integration direction

Select this resolution in order to optimize the measuring times at the revolver head.

Fig. 5.6.28 Measuring mode option, Row measuring mode menu

This menu is used to

– specify the lead measuring method.

– use the package form edges for the rotation windows and/or translation windows.

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, centre measurement, for PLCC, SOJ, for example

– measuring the tips via the outer tips of the leads, for QFP, SOT, SO, for example

Use package form edges

–

for rotation windows

The package form edges can be used to optimally position the rotation windows. However, to do this, the

package form edge must be visible and it must not contain a row of leads.

–

for translation windows

The package form edges can be used to optimally position the translation windows. However, to do this,

the package form edge must be visible and it must not contain a row of leads.

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.
