G-4 Glossary
Model Window: An area defined during the fiducial
location process. The model window encompasses the
fiducial.
Multipass Pattern: A pattern that re-uses one set of
fiducials and height senses to repeat the same pattern at
one or more locations on the workpiece.
Multiple Flow Rates: See Variable Valve Speed.
Needle Heater: Heats dispensing needle to aid in fluid
flow. Installed on some Dispensing Valves. Consists of
a RTD sensor and a heater element attachment.
Controlled by Dispense Head Controller.
Needle Sensor: Located in the front of the dispensing
area. Consists of an L-shaped channel, a ceramic pad,
and a Tactile Sensor. It is used in finding needle XYZ
position. See also Tactile Sensor.
Needle Sensor Substrate: A ceramic pad placed on the
needle sensor and dispensed on during needle location
definition routines.
Non-Recoverable Interlock Condition: You must
completely exit the dispensing software program, re-
start the dispensing software and re-open the program to
continue.
Notepad: A Microsoft Windows accessory software
application that can be used to read .TXT files, such as
the SPC files compiled during Event Logging.
OEM: Original Equipment Manufacturer.
Operation: Functions, such as setting and manipulating
dispensing system controls, by which the operator
causes the equipment to perform its intended purpose.
Operator: A non-technical level position. The
production operator monitors and operates pre-
programmed dispensing systems during production runs
and performs minor routine maintenance.
Operator Interface: The machine/operator interface
that consists of Control Panels, Monitor, software, and
keyboard and mouse.
Outputs: Electrical signals to control devices that must
turn ON and OFF on command.
Pattern: A pattern is a sequence of related instructions,
such as a combination of lines or a set of dots that are
grouped together and saved as a single unit. The pattern
can then be placed or programmed onto the workpiece
at defined locations.
PCB: Printed Circuit Board. The completed PWB with
electrical components installed. Also known as a Printed
Wiring Assembly (PWA).
Personal Protective Equipment (PPE): Clothing and
Equipment worn to reduce the risk of personal injury
from hazards associated with operation, maintenance,
and servicing of the dispensing system. This includes
the wearing of rubber gloves and safety glasses.
Pixels: Abbreviation for “Picture Element”. A pixel is a
single dot in a graphic image. The Computer Monitor
displays pictures by dividing the display screen into
thousands (or millions) of pixels, arranged in closely
spaced rows and columns. A pixel usually consists of
color and brightness information.
Pneumatic Devices: Air pressure actuated devices such
as Stop Pins and Board Pins.
Port: A hardware interface on a computer to which you
can connect a device. Any machine connection that
allows for the exchange of electrical communication
signals. An opening in a mechanical device such as the
vacuum port in a contact heater or the Conveyor port on
the dispensing system.
Post-Dispense Station The part of the dispensing
chamber where a workpiece is held after it leaves the
Dispense Station and before the workpiece leaves the
system. The part may be heated in the Post-dispense
Station, but no dispensing is performed.
Power Manager Module: The Power Manager Module
controls both AC and DC power supplied to all system
components.
Pre-Dispense Station: The part of the dispensing
chamber where a workpiece is held before entering the
Dispense Station. The workpiece may be heated in the
Pre-dispense Station, but no dispensing is performed.
Pre-Fiducial Block: The Pre-Fiducial block is executed
prior to the Main Program. The Pre-Fiducial Block
allows the dispensing program to execute non-dispense
related instructions before the fiducials are found at the
beginning of a dispensing program.
Procedure: FmNT procedures typically handle
“maintenance” functions such as purging or flow rate
measurements.
Process Engineer: A technical level position. The
Process Engineer designs and develops processes for
automated electronic packaging using production line
equipment.
Production Shutdown: When all dispensing has been
stopped under non-emergency conditions such as the
end of a shift.
Prompted Setup: Prompted Setup is a user-prompted
routine to ensure proper offset parameters for the
Camera, Needle, Height Sensor, and Purge/Weigh
Stations.
Psi: Pressure measured in Pounds Per per Square Inch
(lbs/in
2
). English unit of pressure measurement.
Pump: See Valve.
Purge Station: A location at the front of the dispensing
chamber where the Dispensing Valve is automatically
purged at user-defined intervals. A disposable plastic
cup inside of the Purge Station catches the dispensed
fluid.
