Instruction Manual

Glossary - 3
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
performs routine maintenance.
outputs: Electrical signals to control
devices that must turn On and Off on
command.
pattern: A command or set of
commands that use fiducials for
dispensing lines, dots, etc.
pixels: The smallest unit of graphical
data appearing on a computer monitor. 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.
SECS/GEM Interface: SEMI
Equipment Communication Standard
(SECS)/SEMI Generic Equipment Model
for Effective Factory Automation (GEM).
SECS/GEM is the protocol used in cases
where several factory equipment units are
linking together via a Host Computer.
The GEM standard defines useful
conventions for designing the
communications interface on a unit of
factory equipment to improve operations
with a Host Computer.
SEMI: Semiconductor Equipment and
Materials International. An organization
which defines protocols for the
semiconductor industry.
serial communication ports: PC ports
designed to facilitate serial
communication between the PC and
another device.
service stations: The Purge and Weigh
Stations on a dispensing system.
