Fig. 5.7.2 Transfer of package form data with package form manipulation
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.

Important note:
Manipulation of components at the station must be the exception and not the rule.
In general, only a few components have to be changed.
