Glossary G-1
GGlossary
AC: Alternating Current.
Active Air: Active Air provides a very low air flow
rate around the nozzle to provide clean fluid break-
off and prevent nozzle accumulation while
dispensing.
Advanced CPJ+: Advanced CPJ+ was designed for
LED production to maintain the desired fluid weight
per cell within a prescribed tolerance by adjusting the
value of one or more of the following: fluid pressure,
shots per cell and valve on/off times. Advanced CPJ+
automatically adjusts these parameters as required to
maintain a repeatable dot dispense mass
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 FmXP 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.
