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.

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.

In SIPLACE 80 S-20/F

-6/F

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

– Automatic 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.

If a package form is transferred to the station with the .SST file, then the settings for the .SST file for measur-

ing the package form will also be transferred. The package form interpreter will remain inactive.

5.7.2 Flow Charts for Programming and Testing a Package Form (GF)

Components are optically centered in SIPLACE automatic placement systems. It is also necessary to create

the package form description for the component on the SIPLACE line computer first. We recommend that you

always take the package form definitions and dimensions from the data sheet.

The package form settings can be modified at the station. There are different measuring methods. This

means that the lighting settings will also vary. Almost all components can be optically centered by combining

all the setting options in the optimum manner.

You should note, however, that a great many package forms have already been defined as standard. This

means that the manipulation of package forms at the station should be the exception, rather than the rule.

We can also provide the package form definitions of special components and hard to center components as

an extra service. Contact us for further details of this application.
