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.

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

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’ measur-
ing method if the quality is insufficient, for example if the quality factor is less than 50.

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.
If you are placing flip-chips with high reproducibility, i.e. if there is very little difference between the
optical parameters of the flip-chips, we recommend the following settings to guarantee fast place-
ment:
– Switch off the determination of position / presence for components with large balls and spacing.
The position of the components has already been adequately determined using the grid mea-
surement of 3 balls per corner, and the ball presence analysis is unnecessary.
– Do not activate determination of the quality of the measurement unless you want to detect han-
dling or production errors.
Determination of the position is always necessary if the individual ball positions differ greatly from
the grid structure, i.e. if the individual ball positions are fairly scattered about the desired position.

If a package form is transferred to the station without an .SST file, the package form interpreter
will make certain settings to enable the package form to be measured in accordance with the pack-
age form description.
