G-4 Glossary
SC-105HS High Speed Film Coater: Asymtek 5-axis
circulating Fluid Applicator, with a 0-360° rotate
mechanism plus tilt, that applies conformal coating in a
film rather than an atomized spray.
SC-10XVCS Viscosity Control System: The SC-
10XVCS maintains consistent temperature of conformal
coating fluids. The system includes a fluid dispensing
applicator and a heated recirculating fluid circuit to
eliminate viscosity changes in temperature-responsive
materials.
SC-200 Slim Swirl Applicator: Asymtek Fluid
Applicator that uses slim swirl 12-hole nozzles to apply
materials that do not required heating in a bead,
monofilament, or swirl pattern.
SC-204HS High Speed Non-Circulating Film Coater:
Asymtek 4-axis non-circulating Fluid Applicator, with a
0-90° rotate mechanism, that applies conformal coating
in a film rather than an atomized spray.
SC-205 Non-Circulating Film Coater: Asymtek 5-axis
non-circulating Fluid Applicator, with a 0-360° rotate
mechanism plus tilt, that applies conformal coating in a
film rather than an atomized spray.
SCFM: Standard Cubic Feet per Minute. A unit of flow
of a liquid or gas.
SEMI: Semiconductor Equipment and Materials
International. An organization that defines protocols for
the semiconductor industry.
Service Shutdown: When all dispensing is stopped and
the dispensing system is made safe so that servicing can
be performed.
Service Technician: Trained personnel responsible for
performing advanced system servicing procedures.
SMEMA: Surface Mount Equipment Manufacturers
Association. Established protocol for signal
communication between two or more different systems.
Stop Pin (C-740): The Stop Pin is a pneumatic device
used to stop workpieces as they are conveyed into the
system.
SVGA: Super Video Graphics Array. A video card that
produces high-quality color images at high resolution.
Swirl Mode: Conformal coating applied in a conical,
swirling pattern. Available with the SC-200 Slim Swirl
Applicator and Tri-Mode Swirl Box.
System Status LEDs: Located on the Control Panel, the
LED’s are color coded for each System Status
condition. The colors correspond with the colored lights
on the Light Beacon.
TFT: Thin Film Transistor. The Monitor component
that provides color images for a liquid crystal display.
Tool: A tool consists of a dispenser and nozzle, with an
offset from the lower tooling pin of the robot to the tip
of the nozzle.
Tool Offset: The tool offset is the X, Y, and Z distance
from the Robot's lower tooling pin to the tool tip (the
end of the nozzle). Robot position is calculated using
the coordinates of the tooling pin plus the offset.
Tooling Plate (C-741): The Tooling Plate secures the
workpiece for batch system operations.
Tri-Mode Swirl Box: A component of the SC-200 Slim
Swirl Applicator, the Tri-Mode Swirl Box regulates the
air pressure to the fluid applicator. By varying the fluid
pressure, conformal coating materials can be dispensed
in a bead, monofilament, or swirl pattern.
UV-Cure: Curing method that uses ultra-violet light to
cure (harden) coating materials.
V: Abbreviation for volt as in VAC (Volts Alternating
Current). See also AC, DC.
Viscosity: Viscosity is a measurement of the flow
properties of a fluid. The ability of a fluid to resist
deformation under stress. High viscosity fluids have a
high resistance to flow, and low viscosity fluids have a
low resistance.
Water Trap: Moisture from the outside air can
condense in the pneumatic system. The Water Trap
collects this condensed moisture. The Water Trap must
be emptied when it’s full.
Workcell: Dispensing area.
Workpiece: The board or substrate (PCB, PWA, etc. )
or a carrier (pallet, auer boat, lead frame, etc. ) to be
dispensed upon.
X-Axis: Left to right movement of the Dispensing Head
in the dispensing area (Workcell).
X-Beam: The apparatus that spans the width of the
dispensing chamber. The Dispensing Head is mounted
to the X-Beam and slides along it in the X-Axis.
Includes mechanical pulleys for the X-Axis cables.
Y-Axis: Forward and backward movement of the
Dispensing Head in the dispensing area (Workcell).
Z-Axis: Up and down movement of the Dispensing
Head in the dispensing area (Workcell).
