Glossary G-3
Genie Camera: The Dalsa-Coreco Genie M640
communicates bi-directionally to a host computer via
Gigabit Ethernet. No frame grabber is required. The
camera is configured to run at 60 full frames per second
which is twice as fast as the analog PCVision cameras.
A frame can be transferred in 16.67 milliseconds.
Graphic Card:
Computer card that outputs the video
signal to the monitor.
Grounding Strap: A strap worn on the wrist of an
Operator and plugged into front panel jacks to prevent
an Electrostatic Discharge (ESD) that may cause
damage to the workpiece.
Heat Station Timers: Specify the time a part remains
in the pre-heat or post-heat zones.
Height Sensor: A device that measures substrate height
and sends a signal to the system computer. The height
information is used to position the dispensing needle at
an exact distance above the workpiece surface.
High Pressure Relief Valve: Safety feature designed to
prevent the dispensing system from being damaged if
the main air pressure is too high.
Home: The dispense head location whose X, Y, Z
location is defined as the coordinates (0,0,0). The
default setting is where the dispensing head was located
when the system was first turned on. On Nordson
ASYMTEK systems, the default home position is the
front left hand corner of the dispensing chamber.
I/O: Input/Output. Communication between one
component or device and another.
Icons:
Small buttons on a computer screen with a
symbol representing the function that they perform.
Used to execute a menu shortcut.
Impingement Flowmeters: The Impingement
Flowmeters control the airflow through the
Impingement Heaters in the dispensing chamber.
Impingement Heaters: Heaters tooling that does not
come into contact with the part carrier, but blows hot air
up at the part.
Interlock: The Interlock is a built-in safety feature that
automatically removes dispensing system servo motor
power, stopping all dispensing activity, when the hood
is opened. This prevents personnel from being injured
by movement of the dispensing head and conveyor.
Jet: A Fluidmove-controlled non-contact fluid dispenser
that provides high-speed delivery and exceptional
volumetric control for various fluids, including surface
mount adhesive, underfill, encapsulants, conformal
coating, UV adhesives, and silver epoxy. It is excellent
for substrates that may be compromised by contact
dispensing.
kPa: Kilo Pascals. Metric unit of pressure measurement.
Laser Height Sensor: The non-contact Laser Height
Sensor provides high-speed dispense height
measurement for delicate substrates, hybrids, and
integrated circuits that may be compromised by tactile
sensing.
LCD: Liquid Crystal Display. This type of display is
used in the computer monitor.
Lead Frame: A type of workpiece carrier where
multiple workpieces are imbedded in a metal tape.
LED: Light-Emitting-Diode. A semiconductor that
emits light. The materials used in the diode determine
the color of light. Functions as a system status indicator
and as an element in the Camera light source.
Levelers: Four adjustable pedestals (feet) on the bottom
of the dispensing system.
Lift Height: The height that the workpiece is lifted by
the Lift Table at the dispense station of the Conveyor.
Lift Table: Lifts the workpiece a set height at the
dispense station of the conveyor.
Light Beacon: A safety device with colored lights and
an audible alarm that is attached to the top of a
dispensing system. It is part of the Safety Interlock
System.
Linear Encoders: Device mounted on each axis that
keeps track of the actual Dispensing Head position.
Lockout/Tagout (LOTO): The locking and tagging of
equipment during service and maintenance procedures
to help avoid injury or dispensing system damage due to
unexpected energizing of equipment, start up, or the
release of stored energy.
Low Fluid Sensor: A device that triggers a Light
Beacon display or software error message when the
fluid level is low.
Low Pressure Sensor: The Low Pressure Sensor can be
manually set for a pressure from 10 to 100 psi (69 to
689 kPa). The sensor will issue a signal when main air
pressure is lower than the manual set point. This signal
causes the yellow light on the beacon to flash and gives
a software error before dispensing is performed.
Low Pressure Detection Threshold:
The air pressure
level at which the Fluidmove software will issue an on-
screen low air pressure error message.
Machine Offsets: Programming a dispensing sequence
relies on using the camera. Dispensing is accomplished
with the needle or nozzle. Camera-to-Needle and
Camera-to-Height Sensor Offsets need to be established
prior to dispensing.
