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.
Notepad: A Microsoft Windows
accessory software application that
can be used to read .TXT files, such as
the SPC files compiled during Event
Logging.
offset camera: Camera that uses
crosshairs in the Vision System to
locate XYZ locations.
operator: A person running pre-
programmed dispensing systems and

A pixel usually consists of color and
brightness information.
port: Any machine connection that
allows for the exchange of electrical
signals.
post-dispense zone: The part of the
dispensing area where a part is held
after it leaves the dispense zone and
before the part leaves the system. The
part may be heated in the post-
dispense zone, but no dispensing is
performed.
pot-life: The period of time that an
epoxy is usable once thawed.
pre-dispense zone: The part of the
dispensing area where a part is held
before entering the dispense zone. The
part may be heated in the pre-dispense
zone, but no dispensing is performed.
process engineer: A technical level
position. The process engineer designs
and develops processes for automated
electronic packaging using production
line equipment.
production operator: A non-
technical level position. The production
operator monitors and operates pre-
programmed dispensing systems during
production runs and performs minor
routine maintenance.
purge station: A location on the
dispensing system where a suction is
applied to the needle tip forcing the
fluid to flow. A plastic cup inside of the
purge station catches the fluid.
scale: An electronic scale usually
located in the front lower cabinet of the
dispensing system. It is connected to
the software via serial communication
ports.
search window: An area defined
during the fiducial location process.
The search window is the area in
which the Vision System will look for a
fiducial. The default value is equal to
the size of the computer screen.
