ECXP: Easy Coat for Windows XP (ECXP) is Asymtek
proprietary software for use in a Windows XP
environment, developed specifically for Conformal
Coating applications.
Electrostatic Discharge (ESD): Discharge of a static
charge on a person’s body that travels through a
conductive path to ground. An electronic component
may suffer irreparable damage when it is exposed to the
static charge. The sudden transfer of static electricity
from one object to another.
Emergency Shutdown: The coating system is
intentionally stopped suddenly before ending the
program or without using Pause Button to prevent injury
to personnel or damage to equipment. Shutdown is
accomplished by pushing the EMO button or switching
off the Main Circuit Breaker.
EMO: Emergency Machine Off button on the front
panel of the coating system. Cuts power to the coating
system, but does not turn off power to the Power
Manager, Computer, or Monitor. Part of the Integrated
Safety System.
End of Shift: When the Operator ends dispensing for
the day and turns off the coating system.
ESD: Electrostatic Discharge.
E-STOP: See EMO.
Exhaust Vent Duct: The Exhaust Vent Duct is
connected to the facility exhaust system ductwork and
removes fumes from the coating system.
Fan Width Control System: Fan Width Control
provides closed-loop monitoring of the conformal
coating process. The system automatically verifies and
adjusts the fan width prior to and/or after the coating
operation. Fan width programming is done through the
ECXP software.

work area used as a consistent and repeatable point for
positioning and queuing the product that will be coated.
Flexible IR/Convection Module: Asymtek's inline
forced-convection cure module features a flexible
design ideal for mid- to high-volume production.
Coating materials are cured using infrared heat.
Flow Monitoring System: The Flow Monitoring
System monitors the volume of material dispensed. The
coating system can be programmed to stop, pause, or
continue when the dispensed volume falls outside the
preset range.
Fluid Filter: The Fluid Filter blocks small particles in
the conformal coating fluid from passing to the Fluid
Dispensing Applicator.
Fluid Reservoir: The fluid reservoir contains conformal
coating fluid or solvent. It is available in 1-gallon and
5-gallon capacities.
Fuse: A safety device that is designed to automatically
cut off the flow of electricity when the flow of current
through the fuse exceeds its rated capacity.
Gauge: Either an analog or digital device used to
measure internal pressure of fluid or air in a closed
system.
Genie Camera: The Dalsa-Coreco Genie M640 camera
displays a live image of the board and is generally used
for programming purposes. It communicates bi-
directionally to a host computer via Gigabit Ethernet.
No frame grabber is required.
Graphic Card: Computer card that outputs the video
signal to the Monitor.
Grounding Strap: A strap worn on the wrist of an
operator and plugged into the front panel to prevent
electrostatic discharge (ESD) that may cause damage to
the workpiece.
Home: The home position of the Robot is a known
position within the workspace defined by X, Y, and Z
coordinates. It is generally located at the front left of
the Workcell.
Hour Meter: Monitors the coating system operation
hours for maintenance logging.
Humidified Conveyor Module: Asymtek’s Humidified
Conveyor module offers accelerated curing for moisture
cure materials.
I/O: Input/Output. Communication between one
component or device and another.
Icons: Small buttons on a Computer screen with a
symbol representing the function that they perform.
Used to execute a menu shortcut.
Infrared Heat: Curing method that uses infrared or a
convection oven to cure (harden) coating materials.
Inline Inverter Module: Inverts the workpiece so that
both sides may be coated. Provides for a “true” inline
process by virtually eliminating manual handling of the
workpiece.
Interlock Door Sensors: The Interlock Door Sensors
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.
kPa: Kilo Pascals. Metric unit of pressure measurement.
Glossary G-3
Laser Fan Width Control System: Laser Fan Width
Control provides closed-loop monitoring of the
conformal coating process. The system automatically
verifies and adjusts the fan width prior to and/or after
the coating operation. Fan width programming is done
through the ECXP software.
Laser Pointer Programming Tool: Projects a red dot
onto the workpiece, which simulates the center point of
the dispensing module for faster identification of
program begin and end points.
LED: Light-Emitting-Diode. A semiconductor that
emits light. The materials used in the diode determine
the color of light. Functions as a system status indicator
and as an element in the Camera light source.

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.
