The Core and Prime SC-400 PreciseCoat

Fluid
Systems are ideal for applying coating materials to
highly selective areas. The applicator is designed for
coating small substrates, substrates with high-
component density, and situations where there are
tight tolerances between coated and uncoated areas.
The needle design with jetting action and fast pulse-
width modulated control allow the SC-400 jet to
reach locations that cannot be accessed by other
applicators. Small volumes and better material
control deliver line widths down to 1.2 mm (0.05
in.) wide. The need for masking is eliminated
because the flow is so closely controlled.
Easy Coat software creates process synergy between
the unique applicator and platform design by
providing routines and validation steps to define the
optimal start and stop points during production.
This allows coating materials to be consistently
applied to the exact programmed locations.
Multiple dot sizes can be delivered from the same
applicator, yielding small volumes with good
volume control. The SC- 400 also allows for
clearance above large components on a board, and
its performance is virtually unaffected by warped
substrates.
The Core SC-400 fluid system includes one 1-gallon
fluid reservoir, one applicator, two manual pressure
regulators with gauges, and one box of needles. To
optimize the Prime SC-400 fluid system for your
production, you have a choice of two fluid
reservoirs of either 1- or 5-gallon capacity. One
applicator and three boxes of needles are included.
With the Prime fluid system, fluid pressure is
controlled by two E/P regulators through Easy
Coat software.
The SC-400 applicator is available for use with the
Select Coat

The SC-400 is also available with a heated circulating fluid system that maintains a constant fluid temperature so
that viscosity is unaffected by ambient temperature changes. 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.

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 and set the pitch as part of the programming.
• Coat two parts at once – reducing overall cycle time
• Enable the second applicator as needed
• Fully adjustable pitch
Four-Position Tilt – Additional Benefits
The four-position tilt option features the standard vertical position and tilts the applicator
at 30 degrees in four positions: right, left, forward, and backward in 90 degree increments.
This option provides enhanced versatility in droplet dispensing and is controlled through
Easy Coat software. Programmers can set and modify specific tilt and rotate parameters
for each coating element.
