PLEASE NOTE:
Measurement mode grid can be speeded up, if measurement mode Size is carried out beforehand.
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. 5.6.42 ’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, for critical components 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 BGAs, µBGAs, or flip-chips with high reproducibility, i.e. if there is very little difference bet-
ween 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.

5.7 Guidelines for Describing Package Forms
5.7.1 Transfer of Package Form Data and the Package Form Interpreter
If a package form is transferred to the station without an .SST file, the package form interpreter will make cer-
tain settings to enable the package form to be measured in accordance with the package form description.

automatic placement machines, the package form interpreter is located in the machine
controller. The communication module transfers the signals for controlling the lighting from the MC to the cameras.
Tasks of the Package Form Interpreter
Automatic selection of suitable measuring modes
Automatic selection of the measuring parameters
Differentiation between cubic/not cubic
Automatic setting of the lighting
The package form interpreter processes standard components and automatically identifies special compo-
nents. Under certain circumstances, other components have to be post-processed. If the package form set-
tings have to be manipulated, these changes will be stored in the .SST file and transferred back to the line
computer.
