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.

If you are inserting 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 insertion:

– Switch off the determination of position / presence for components with large balls and spacing. The posi-

tion of the components has already been adequately determined using the grid measurement 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 handling or pro-

duction 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.
