Adhesive pattern
In this field the number of the adhesive pattern is entered that has been
defined for the current package form (see chapt. 7).
-
Dispense setting
In this field a number from 1 to 10 is entered indicating the volume to be
dispensed. The number denotes the quantity of adhesive preset at the
adhesive metering unit for the corresponding adhesive volume setting.
The lowest setting (1) corresponds to the smallest adhesive quantity
dispensed.
NOTE
In the fields "Placing force" and "Dispense setting" numerals must
be entered.
If no number is entered in the field "Adhesive pattern" a default value of "1" automatically applies
to the adhesive pattern, i.e. the adhesive dot is applied centrically with respect to the placement
position.
Procedure to be followed for editing:
●
Click on editing field, enter appropriate number and confirm the entry by pressing the
RETURN key.
NOTE
If invalid numbers (e.g. number too small or too high for the placing force) or characters and
letters have been entered, the fields containing the invalid values are surrounded by a red frame and
must be corrected.

6.1.3 Package Form Definition
6.1.3.1 Definition of the Component’s Coordinate System
NOTE
For the description of a component’s package form, the dimensions should, as a rule, be taken from the corre-
sponding data sheet. Please note, that the description always refers to a component as seen from above.
The component is displayed in its 0°-description in the view area of the Package Form Editor. Here, the origin
of the coordinate system is always located in the center of the view area. From there, the X-axis points to the
right, the Y-axis points upward. It is also possible to describe a component both in horizontal and in upright
position (see Fig. 6.1.12). As a rule, the center of the component coincides with the zero point of the coordinate
system.

The 0°-description of the standard package form contained in the package form library (GF-Bibliothek) is sub-
ject to certain rules which should also be observed for the creation of customer-specific package forms. It can
thus be ensured that different programmers can work with uniformly defined package forms. In this way it is
possible to determine, for example, the pick-up angle at the station without having to check the 0°-description
in the Package Form Editor.
An incorrect 0°-description may result in pick-up or vision errors at the station.
To avoid such errors, the following rule should be observed:
Rule: The long side of nozzles featuring rectangular suction areas is to be positioned along the
X-axis.
This means that die X-axis of the component points in the direction where the nozzle will make contact with the
long side of its suction area (see Fig. 6.1.13).
Exception: special nozzles with 90°-displacement

If the aforementioned rule is not observed, it may happen that the incorrect 0°-description will result in the errors
depicted below (see Fig. 6.1.14).
