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.

NOTE

This value should only be modified for special components and plugs. Deactivate lead measurement for white

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.

Measuring mode

option,

Lead measuring mode

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.

Measurement

If the inner lead tips are mapped better than the outer tips, for example if a shiny lead is bent upwards slightly,

you can select one of the following options:

Windows

–

Separately for each lead

Here you define the window in the primary direction (dark blue) and secondary direction (light blue) for

measuring each standard lead for irregular components and special components.

–

Combined window

Used to define a common window for all the leads. This applies to four-sided, symmetrical components

only.

option,

Grid measuring mode

In this menu, enter the number of balls to be measured at each corner:

– 3 for single measurement

– 5 for multiple measurement
