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

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.

ECXP, other than the Main Pattern, are expressed as a
set of coordinates in the Product Frame. The pattern
origin coordinates are stored in the Pattern Edit Frame
when the pattern is created. See also Product Frame,
Base Frame, and Reference Frames.
PCB: Printed Circuit Board. The completed PWB with
electrical components installed. Also known as a Printed
Wiring Assembly (PWA).
Personal Protective Equipment (PPE): Clothing and
Equipment worn to reduce the risk of personal injury
from hazards associated with operation, maintenance,
and servicing of the coating system. This includes the
wearing of rubber gloves and safety glasses.

single dot in a graphic image. The Computer Monitor
displays pictures by dividing the display screen into
thousands (or millions) of pixels, arranged in closely
spaced rows and columns. A pixel usually consists of
color and brightness information.

allows for the exchange of electrical communication
signals. An opening in a mechanical device such as the
vacuum port in a contact heater or the conveyor port on
the Coating system.

controls both AC and DC power supplied to all system
components.
Process Engineer: A technical level position. The
Process Engineer designs and develops processes for
automated electronic packaging using production line

Product Frame: Product frames exist within the Base
Frame. ECXP uses fixture constraint coordinates, plus
the length and width of the product, to calculate the
coordinates of the Product Frame within the Base
Frame. The Product Frame origin is the calculated Main
Pattern Edit Frame. See also Base Frame, Pattern
Frame, and Reference Frames.
Production Shutdown: When all dispensing has been
stopped under non-emergency conditions such as the
end of a shift.

with electrical components installed. Also known as a
Printed Circuit Board (PCB).
PWB: Printed Wiring Board. An insulating board
containing conductive tracks for electrical circuit
connections on which chips and other electronic

Reference Frames: All positioning in the workcell is
done with reference to sets of position coordinates,
called Reference Frames. In ECXP, three different sets
of Reference Frames are used: Base Frame, Product

ventilation path when the drawer is pulled out for
maintenance.
