Click on the ‘Setting’ field for the ‘Size’ measuring mode to overlay the

Size measuring mode

menu on the

screen.

Measuring mode

option,

Size measuring mode

This menu is used to

– vary the resolution the angle calculation.

– specify the method for the rotation calculation and

– vary the integration settings.

Resolution for the angle calculation

In this measuring mode, if the component rotation has been calculated incorrectly on account of ambiguity,

you can increase the angular resolution in order to determine the angle of rotation. The following increments

may be used in relation to the resolution in order to determine the angle of the components:

– Simple components: Low resolution:

– Complex components: High resolution

Method for calculating the rotation

Here you must specify the number of rotation windows in order to determine the angle:

– Automatic selection

The system selects the number of windows.

– SWIN method (Single Window)

Selects a single window. This method is suitable for small complex components and fluctuating dimen-

sions.

– TWIN method (Two Windows)

Two windows are selected. This method is particularly suitable for rapid analysis, for PLCCs, for example.

However, this requires the structures to be investigated to lie in the center of the window. If this is not the

case, select just one window (SWIN method).

Integration settings

If you click on the ’Integration settings’ field, the

Integration settings of Size measuring mode

menu will

appear on screen.

Integration settings of Size measuring mode

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.

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
