Glossary
AC: Alternating Current.
Bar Code Recognition System: The Bar Code
Recognition System uses a bar code label mounted on
the workpiece to select a coating sequence.
Base Frame: All positioning in the workcell is done
with reference to sets of position coordinates, called
Reference Frames. In ECXP, the Base Frame is the set
of coordinates (X, Y, and Z) that define the robot's
travel. See also Product Frame, Pattern Frame, and
Reference Frames.
Board Pinning Assembly - Features a board pinning
sensor and locates the board in terms of X/Y location
and rotation.
Board Present Sensor: Registers the presence or
absence of a workpiece prior to dispensing. It initiates
the coating sequence only when a workpiece is in place.
Brush Box: The Brush Box mounts to the Conveyor
and is used to clean the dispensing nozzle.
Carrier Height: The height that the carrier holds the
workpiece above the Conveyor or Tooling Plate.
Carrier: A device such as an Auer Boat or Lead Frame
onto which workpieces are mounted and carried during
the dispensing process.
CE: The abbreviation of the French phrase "Conformité
Européene" which literally means "European
Conformity.” CE qualification indicates that a
manufacturer's electric/electronic equipment product
complies with European Union health, safety, and
environmental protection Product Directives
(standards). CE qualification means that the product can
be legally sold and freely transported within European
Union markets.
Characterization: The process of selecting the
appropriate responses to compensate for variables in the
Conformal Coating process. The variables include
factors such as material type, temperature, thickness, air
pressure, fluid applicator velocity, and type of surface to
be coated.
Chip: Also called a die. A small piece of
semiconducting material (usually silicon) that contains a
discrete component or an embedded integrated circuit.
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.
Circuit: A combination of electrical or electronic
components, interconnected to perform one or more
specific functions.
Cleaning Agent: A solvent or other cleaning liquid
recommended by the dispensing fluid manufacturer’s
Material Safety Data Sheet.
Coating Applicators: Conformal Coating fluid
applicator. Supported applicators include the
SC-104HS, SC-105HS, SC-204HS, SC-205HS, SC-300
and SC-400 Fluid Dispensing Applicators. The SC-100
Series Film Coaters are recirculating applicators. The
SC-200 Series applicators are noncirculating.
Noncirculating fluid applicators are used to apply
materials that do not require heating and therefore, are
not circulated.
Coating Area: Area where the coating operations take
place.
Conformal Coating: A material that is applied to a
circuit board to provide protection from chemical and
mechanical damage.
Curing Process: The second step in the Conformal
Coating process. After a coating material has been
applied, it must be cured (hardened).
Current: The flow of electrons through an electrical
circuit. Usually measured in amperes.
DC: Direct Current.
Die: See Chip.
Dispensing Area: See Coating Area
Dispensing Head: The robotic coating applicator that
moves during the dispensing operation. The coating
applicator is mounted on the Dispensing Head. Also
referred to as the Z-Head or Robot.
Dispensing Runs (Wet/Dry): A wet dispensing run is
when fluid is dispensed. A dry run is when the program
is executed but no fluid is dispensed.
Dual Simultaneous Mounting Bracket: Doubles
dispensing capability by accommodating two identical
applicators side by side for simultaneous dispensing of a
single fluid.
Dual Toggle Mounting Bracket: Accommodates dual
Fluid Applicators. Typically uses an SC-105, SC-200,
or SC-205 Film Coater plus a needle type Dispensing
Valve (such as Asymtek’s DV-03, DV-05 or DV-09) to
separately coat broad areas of the board, as well as areas
requiring smaller amounts of coating material

detect the hood status (open or closed).
Interlock Shutdown: When an interlock shutdown
occurs, the motor power turns OFF, the system loses
master references, and the red beacon light illuminates.
The program WILL NOT resume from where it stopped.

Low Air Pressure Sensor: If the air pressure drops
below a set point, this sensor alerts the operator of
pressure drop conditions.
Low Fluid Scale: The Low Fluid Scale detects a low
fluid condition by weighing the fluid reservoir. If the
weight drops below a preset value, a sensor triggers the
Light Beacon display and the software issues a warning
message. The sensor can be set to a level that provides
ample time to refill the reservoir before reaching an out-
of-material condition. The Low Fluid Scale is used for
fluids where direct contact with the sensor is not
feasible.
Low Fluid Sensor: The Low Fluid Sensor triggers a
Light Beacon display and software warning message
when the level of coating material is low. The sensor
can be set to a level that provides ample time to refill the
reservoir before reaching an out-of-material condition.
The Low Fluid Sensor is located within the external
reservoir and is used for fluids that allow direct sensor
immersion.
Low Solvent Cup Sensor: The Low Solvent Cup
Sensor triggers a light beacon display and software
warning message when the level of solvent in the cup is
low. The software timer can be set to a level that
provides ample time to refill the cup before reaching an
out-of-solvent condition.
