Glossary G-1
GGlossary
AC: Alternating Current.
Area Fill: Dispensing lines of fluid within a geometric
pattern to completely cover an area.
Auer Boat: A metal material handling plate used to
transport parts into automated systems.
Automatic Fiducial Locating System: A vision system
that finds fiducials and compensates for small changes
on a workpiece during dispensing.
Automove Control Language (ACL): An Asymtek
proprietary motion control language consisting of
commands that control all components of the dispensing
system.
Axis: X, Y or Z geometric dispensing coordinates. See
Figure G-1.
Figure G-1 XYZ Axis Definition
Bar Code Recognition System: The Bar Code
Recognition System uses a bar code label mounted on
the workpiece to select a dispensing program.
Bias Limits: Bias limits are the maximum and
minimum bias range values that FmNT will allow. See
also Dispensed Weight Bias and Valve Bias.
CAD: Computer Aided Design.
Calculate Master Offsets: Calculate Master Offsets is a
setup routine that identifies and records a Safe Z Height
for Dispensing Head travel and the XYZ locations of the
Purge/Weigh Stations. It also calibrates the Camera
crosshair to known locations. Calculate Master Offsets
is only available on M-600 Series Dispensing Systems
equipped with a Needle Sensor. It is not available on
M-2000 or X-1000 Series Dispensing Systems.
Caliper Tool: A vision tool, used in the Corner Finder
Method for identifying fiducials, designed to find edges
or pairs of edges.
Camera Offset: The calibration of the XY location of
the Camera with respect to the dispensing needle.
Camera-Assisted Scripted Valve Offsets: A setup
routine that allows you to perform one or all of the setup
procedures one step at a time. It uses the Camera for
alignment tasks, eliminating the need to put any body
parts into the dispensing area.
Carrier: A device such as an Auer Boat or Lead Frame
onto which workpieces are mounted and carried during
the dispensing process.
Carrier Height: The height that the carrier holds the
workpiece above the Heater Tooling or Conveyor belt.
Chip: Also called a die. A small piece of semiconducting
material (usually silicon) that contains a discrete
component or an embedded integrated circuit.
Chip Offset: Chip Offset is the distance between the
edge of the part (usually a die) and the edge of the
dispensing needle and is primarily used for underfill
applications.
Circuit: A combination of electrical or electronic
components, interconnected to perform one or more
specific functions.
Circuit Breaker: An automatic switch that
automatically cuts the electrical supply to the system
when the power current exceeds the set level. Some
circuit breakers can be manually operated to turn power
off and on for servicing or maintenance purposes.
Conveyor Atom: A set of ACL commands that controls
the Conveyor.
Conveyor Controller Module: The Conveyor
Controller Module monitors the SMEMA interface and
controls the Conveyor indexing operations.
Crosshairs: Two lines intersecting at a 90° angle in the
center of the Video Display of the Computer Monitor.
Used to teach dispensing points to the FmNT software.
DC: Direct Current.
Die: See Chip.
Dispense Station: The part of the dispensing area where
dispensing is actually performed.
Dispensed Weight Bias: Generally used with Weight
Control Lines. If the weighed fluid is consistently over
or under the desired percentage of fluid after a flow rate
calibration, you can set the bias to compensate for the
variation. See also Bias Limits and Valve Bias.
Dispensing Area: The interior area of the dispensing
system where dispensing operations are performed.
Dispensing Head: The robotic fluid applicator that
moves during the dispensing operation. The Dispensing
Valve, Height Sensor, and Camera and Lighting are
mounted on the Dispensing Head. Also referred to as the
Z-Head or Robot.
