Resolution in the integration direction

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

5.6.4.17 ’Row’ Measuring mode

Click on the ‘Setting’ field in the

Row measuring mode

menu to call up the following menu:

option,

Row measuring mode

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 (eg white plugs).

–

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.

PLEASE NOTE:

Do not use measurement mode Row together with measurement mode Size.

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. We recommend to choose the resolution ’High’ or ’Very high’.

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.

Measuring mode

option,

Corner measuring mode

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.
