NOTE
If invalid values were entered, a dialog box containing a corresponding error message is displayed
(see page 6 - 12). The fields containing the invalid values are surrounded by a red frame. The dialog
box must first be acknowledged by clicking on
OK
. Thereafter, the entries can be corrected and con-
firmed by clicking on "OK".
Setting the Features of the Balls Within a Grid Group
The characteristic features of the balls of a selected grid group can be defined with the aid of the buttons
"El. connection" and "Centering fiducial" in the setting area of the "Model description" window (see Fig. 6.1.12).
-
El. connection
If this button is activated, all balls of a selected grid group can be defined to be electrically conductive.
☞
NOTE
By default, the button "El. connection" is automatically activated when the "Model description" window
is opened. This means that all balls within the grid groups are designated as an "El. connection", i.e.
they are electrically conductive. This setting can subsequently be changed for each individual grid
group.
Procedure:
●
Select any ball from the grid group whose balls are to be defined as "electrically not conductive",
by double-clicking.
●
Deactivate the
El. connection
button in the setting area.
Now, the balls of the selected grid group are not conductive.
-
Centering fiducial
The selected grid group can be defined as an alignment structure for the determination of the position
of the component at the nozzle.
(This function is not implemented in the present software version).
Changing a Ball Model
☞
NOTE
The procedure for changing the data of a defined ball model is the same as for changing a pin model
The relevant procedure is described on page 6 - 21.

6.1.2.9 Package Form Editor Selection Fields - "Handling data" Display
In the selection fields a button is located next to each "handling type" (see Fig. 6.1.4).
The required "handling type" can be activated or deactivated by clicking on the corresponding button.
Selection field "Handling instructions"
This field serves to define the type of handling a component type will be subjected to during the placement
cycle.
-
Vacuum test during pick-up When the component is picked up sensors are used to
check whether the component has been picked up.
-
Vacuum test during placement When the component is placed sensors are used to check
whether the component has been placed.
-
Coplanarity check The coplanarity laser module determines by means of co-
planarity measurement whether pins of the component
are bent and whether it may have to be discarded.
-
Good nozzle contact In the case of cubic components, this setting provides
good nozzle contact by means of adequate vacuum supply.
Selection field "Centering"
This selection field serves to define the type of centering suited for the component type. For this purpose, the
setting "Centering in head" or "External centering" can be chosen from. Moreover, the centering procedure for
the particular centering type can be defined.
- Centering in head
The component is centered in the placement head if any
one of the three following options is selected in addition.
with H jaws mechanical centering by means of h-jaws
(not possible on SIPLACE 80)
with Z jaws mechanical centering by means of z-jaws
(not possible on SIPLACE 80)
with camera optical centering by means of head camera
(not possible on HS-180)

- External Centering
The component is centered externally by means of the
optical or mechanical centering station.
(Not possible on Siplace 80S).
optical The component is centered using the (external) optical
centering station.
mechanical The component is centered using the (external) mechanical
centering station.
(At present not operational)
Rotate before centering The component is turned (by 90° or 270°) prior to being
placed in the centering station.
Selection field "Reduced acceleration"
When the setting "Special handling" is activated in the selection field you can reduce the speed at which the
placement head moves when performing pick-up, centering or placement operations along the x, y, z and
d-axes. It is thus possible to handle and and place also large components (e.g. PLCC's 84) securely.
- Special handling
"Special handling" is defined for the pick-up, centering and
placement cycles of a component.
Z during pick-up reduced acceleration in z-direction when component
is picked up from its pick-up position
X during centering reduced acceleration in x-direction when component is
centered (at present not operational)
Y during centering reduced acceleration in y-direction when component is
centered (at present not operational)
D during centering reduced acceleration in d-direction (turning) when
component is centered
X during placement reduced acceleration in x-direction when component is
placed (deposited)
Y during placement reduced acceleration in y-direction when component is
placed (deposited)
