Instruction Manual

Glossary - 2
flow rate: The amount of fluid in
milligrams per second that is flowing
from the valve.
gantry: A non-conveyorized dispensing
area on a non-conveyorized dispensing
system.
heaters: Either contact or infrared
modules located between the conveyor
rails or inside of the tooling plate (in the
pre-dispense, dispense and post dispense
areas of the dispensing system). Used to
heat parts during dispensing and control
the cure of the epoxy.
height sensor: An instrument used to
locate the surface of the substrate to
determine its height and record the
information so the dispense tip can be
positioned at an exact distance above the
surface, ensuring consistent dispensing.
home: The dispense head location
whose (X,Y,Z) location is defined as
(0,0,0). The default setting is where the
dispense head was located when the
system was first turned on.
icons: Small symbolic buttons used to
execute a menu shortcut.
I/O (Input/Output): Communication
between one component or device and
another.
JIT program: A Just-In-Time fluid
delivery schedule based on fluid shelf-
life. The schedule is worked out with the
distributor to prevent over-stocking so
fluid shelf-life does not expire before it is
used.
kPa: Air pressure measured in kilos per
square one thousand Pascals.
lead frame: A type of part handler
where multiple parts are imbedded in a
metal tape.
LED light: Light-Emitting-Diode. The
needle sensor has an LED indicator light.
LLHC: Lower left hand corner.
load cell: A sensor located on Model
NSZ needle sensors that is used as a
touch point for substrate height
measurements. The needle sensor probe
touches down on the load cell which
records the value (Automatic Height
Sensor Calibration).
LRHC: Lower right hand corner.
Material Safety Data Sheet (MSDS):
Information for the safe use of materials.
Generally included in the fluid packaging.
message areas: In a Windows program,
these are areas or boxes that contain
information for the operator.
micro pots: Dispensing technique for
filling divots or voids on the substrate or
part.
mil: One thousandths on an inch, or 1 x
10
-3
inches.
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 to repeat the
same pattern at one or more locations on
the workpiece.
needle sensor: An instrument used to
locate the position of the dispensing tip in
the X-Y-Z directions.
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.
