6.7.2 Flow Charts for Programming and Testing a Package Form (GF)
Components are optically centered in SIPLACE automatic placement systems. It is also neces-
sary 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. 6
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 cen-
tered by combining all the setting options in the optimum manner. 6
You should note, however, that a great many package forms have already been defined as stan-
dard. This means that the manipulation of package forms at the station should be the exception,
rather than the rule. 6
We can also provide the package form definitions of special components and hard to center com-
ponents as an extra service. Contact us for further details of this application. 6

Important note:
The manipulation of
components at the station
must remain the exception,
rather than the rule.
In general, only a few
components have to be
changed.
1. Handling error: pick-up angle,
nozzle type, CO on nozzle etc.
2. Display component
3. Modify lighting
4. Modify measuring modes
and measuring parameters
5. Modify component dimension
6. Modify pin/ball contrast
7. Modify pin/bal
dimensions
8. Program contrast
