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.

Fig. 5.6.31 Measuring mode option, 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.

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:

– measuring the tips via the inner tips of the leads, for bases, for example

– center of the lead, center measurement, for PLCC, SOJ, for example

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

Windows

–

Separately for each lead

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

measuring each lead for irregular components and special components.

–

Combined window

Used to define a common window for all the leads.

5.6.4.20 ‘Grid’ measuring mode

Click on the ‘Setting’ field in the ‘Grid’ measuring mode to call up the Grid measuring mode menu.

5.6.4.21 ’Ball’ measuring mode

Click on the ’Settings’ button in ’Ball’ measuring mode to call up the ’’Ball measuring mode“ menu.

Fig. 5.6.33 ’Measuring mode’ option, ’’Ball measuring mode“ menu

This menu can be used to

– select the measuring methods listed under ’Measurement’ and

– evaluate the position and presence of balls and carry out a quality analysis.

Measurement

You can choose between the following measuring methods:

– the profile method for fast analysis or

– the filter method for a more robust measuring method, although this will take longer.

The ’fast’ measuring method is generally sufficient. However, we recommend the ’robust’ measuring method if

the quality is insufficient, for example if the quality factor is less than 50.

Analysis

This is used to analyze the position of the balls and to determine whether they are present. It can also be used

to determine the quality of the measurement. The quality of the measurement should generally be better than

50.
