SC-280 Film Coater
Precise Non-Atomized Conformal Coating Application
The SC-280 Film Coater Fluid Systems optimize
throughput and increase yield by delivering high
velocity, excellent edge definition, improved
response time and on/off rates, and the ability to
use a variety of coating widths. When combined
with the SL-940 Prime Process Controls option,
the SC-280 Prime fluid system can utilize multiple
fan patterns within one program.
Easy Coat
®
software creates process synergy
between the applicator and platform design
through routines and validation steps that are used
to define the optimal start and stop points during
production. The film coater provides automated,
selective application of conformal coating materials
with viscosities less than 100 centipoise.
Programmable applicator modes – spots, lines, and
area coverage – provide powerful coating results.
The SC-280 ensures a consistent fan pattern – even
after idle – through the unique design that
circulates heated fluid through the applicator
extension maintaining a consistent nozzle
temperature at all times. Programmers define the
process temperature and the corresponding process
limits in Easy Coat software. If the fluid
temperature moves outside the defined process
limits during production, the system triggers an
alarm condition and operators can intervene to
prevent potential errors.
To optimize the Prime SC-280N and SC-280C
Film Coater Fluid Systems for your production,
you have a choice of two nozzles and two fluid
reservoirs of either 1- or 5-gallon capacity. Fluid
pressure is controlled electronically through Easy
Coat software. The SC-280N and SC-280C
programmable fluid pressure is contingent on the
optional Prime Process Controls.
The SC-280N Film Coater Fluid System is also
available in a Dual-Simultaneous configuration.
The SC-280 applicators are intended for use with
the Select Coat
®
SL-940 conformal coating system.
SC-280N Film Coater with
Fourth Axis
Features and Benefits
High coating velocity up to 750 mm/sec
With a transfer efficiency of virtually 100 percent, the Film
Coater applicator improves conformal coating utilization by 30-
50 percent
The non-atomized design minimizes common problems such
as over-spray, masking, and rework
Wet coating thicknesses range from 125 to 750 µm (0.5 to 3
mils) for solvent-based materials and 0.1 to 0.2 mm (4 to 8
mils) for 100-percent solid materials
Stainless steel fluid path – compatible with a variety of
conformal coating materials
Easy maintenance and setup routines
Simple conversion between non-circulating and circulating
configurations – to meet future production needs
The standard Fourth Axis provides a 0 – 90 degree rotation of
the fan pattern
Optional Fifth-Axis Tilt accessory increases accessibility t
o tight
or difficult-to-reach areas by providing four tilted positions
Available in a Dual-Simultaneous configuration – reduces
coating process time by 50%
The SC-280C heated, circulating fluid system provides closed-
loop temperature control and allows viscosities to remain
independent of the ambient environment

Featured Options
Fifth-Axis Tilt
Laser Fan Width Control
Dual-Simultaneous Programmable Pitch
Fifth-Axis Tilt – Additional Benefits
Fifth-axis tilt allows the film coater nozzle to be rotated and tilted to access hard-to-reach areas of the product that
may not be achievable with the standard downward approach (0 degrees). Programmers can easily set and modify
the rotate and tilt parameters for an applicator within Easy Coat
®
software.
• Ideal for coating vertical surfaces and underneath components
• The nozzle can tilt at 30 degrees, and the mechanism can be rotated in 4 positions – in 90-degree
increments (0, 90, 180, and 270) to direct the fan pattern to the left, right, front or back to coat all four sides
of a component
• The nozzle is fully integrated into the applicator assembly and can be installed horizontally for a narrow
coating pass when it is tilted or vertically to achieve vertical area coverage
• Tilting of the nozzle as opposed to tilting the entire applicator eliminates the need for a direct line of sight
and provides optimal agility during the conformal coating process

Dual Simultaneous – Additional Benefits
With the dual-simultaneous configuration, the SL-940 system can coat two parts
(multiple-up) at the same time. Processing two parts in parallel significantly improves
the throughput, while maintaining high yield. The actual conformal coating process time
is reduced by 50%, so that throughput performance can be significantly increased –
especially when conducting a high takt time conformal coating process with few
overhead movements.
Two of the same applicators are installed and operate simultaneously. When there is no
need for simultaneous conformal coating, Easy Coat
®
software allows the programmer
to disable the second applicator as part of the programming.
• Coat two parts at once – reducing overall cycle time
• Enable the second applicator as needed
• Fully adjustable pitch
