Parameters
Down Speed The rate in inches per second that the dispensing head descends to
the point where dispensing begins.
Up Speed The rate in inches per second that the dispensing head will go up
after each dispense.
Acceleration The rate at which the dispensing head goes from being stopped to
reaching either the designated Down Speed or Up Speed.
Max. Search Establishes a maximum distance that the dispensing head
Distance descends from absolute zero when searching for the
substrate
surface. If the Height Sensor does not locate the substrate surface
within the Max. Search Dist. Parameter, an error box will appear
in the center of the screen. Adjust the distance accordingly.
Retract The vertical distance the dispensing head moves upwards after
Distance dispensing. The Retract Distance must be within the Safe
Z-Height. Retract Distance can be reduced to increase dispensing
speed.
Height Sensor Setup
The Height Sensor Setup procedure varies depending on the Height Sense Mode. Perform
the Setup procedure that relates to your Height Sense Mode.
To perform Setup for Height sense always Mode:
1. Load a board or part into the dispensing area, if one is not already present.
?NOTE Since you are teaching the Z-offset of the needle to the Height
Sensor, it is NOT necessary to use a board identical to one used
in production.
2. Make sure that the Height Sensor probe is in the up position.
> If the probe is not in the up position, consult the Height Sensor section of the
Millennium Operations Manual for troubleshooting procedures.
3. Click on Next.
4. Make sure that the probe is in the down position.
> If the probe is not in the down position, consult the Height Sensor section in the
Millennium Operations Manual for troubleshooting procedures.
5. Click on Next.
6. Use the position control buttons to move the dispensing head to a dispensing
location on the workpiece.
