Glossary G-1

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

G-2 Glossary

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.

Fixture: Fixture is defined as the location inside the

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.
