Situational Awareness and Threat Environments

Todays “in-theatre” shipboard needs demand C5ISR Systems to be fully
operational 100% of the time.

Complicating these needs are: Asymmetrical threats, High demand mission cycle
times with limited intervals for maintenance and support activities, evolving
environmental conditions and COTS/RoHS products in use for Military
applications.

Reality is that C5ISR systems are expected to operate in real time “come as you
are” status with 100% reliability regardless of threat or environmental
conditions.

Given the varying and dynamic nature of Mission requirements, growing
complexity of electronic systems and the need to operate in smaller packages in
increasingly hostile environments, electronics must be ruggedized at the
component and PCB level.
PRS Proprietary
Response/Engineering Solutions

The Security services of the U.S. have been mandated to use COTS
componentry in all electronic (including C5ISR) systems.

The reliability and certainty of mission success may be put in jeopardy as COTS
products were never intended for military application or environments.

Couple this with RoHS/lead free material and reliability of system performance
(and thus Mission effectivity) may be subject to further degradation.

To better insure survivability and performance any PCB’s (and probably
some mechanical product) associated with Communications, EW, Fire
Control and any other Mission critical electronics must be coated or
encapsulated with mil-rated materials.
PRS Proprietary
Forward Looking Proactive Action


To insure mission success from the outset it is necessary to spec into any RFQ or RFI an
environmental requirement so that the design integrates an environmental solution with the
overall system.
Too many times a design passes a well thought out Qualification testing process only to find
out in the LRIP or Preproduction phase that tin whiskers or corrosion or an EMI/RFI issue
has arisen that was unaccounted for.

Plasma Ruggedized Solutions has worked with various A&D Tier 1 and Tier 2 firms for more
than 23 years creating lifecycle cost-savings applications to insure high MTBF mission critical
performance.

Featuring more than 2.5K types of coatings and encapsulates PRS engineering designs and
creates custom ruggedized solutions for specific threat environments.

In the following set of charts we will discuss engineered approaches for dealing with various
threat environments that electronic and mechanical systems face in theater.

Potting / Encapsulation is the process used to protect
“ruggedize” electronics. Potting provides protection from
extreme environments, against shock and vibration,
ensures security of sensitive designs, as well as creates a
barrier against moisture, fungus, dust, and corrosion.
Potting can also enhance circuit reliability by reducing
leakage from high voltage circuits, protecting against
voltage arcs and short circuits and by preventing the
formation of “tin whiskers.”
Potting or Encapsulating a circuit can make it Federal
Information Processing Standards (FIPS) compliant.
Because Potting and Encapsulating encloses the entire
assembly, the assembly is protected from unauthorized
entry, modification and reverse engineering.

Material Development - Kryptos
Plasma Ruggedized Solutions recently began developing new materials in-house for our
conformal coating, potting, encapsulating, and other processes. Certain applications can be
carried out perfectly with standard materials, but others require something more specialized.
Our materials development processes give us a unique ability to create the perfect/tailored
material to match your project's exact specifications.
•
The KRYPTOS™ product line is highly adaptable, of which KRYPTOS-17™ is a filled, RoHS
compliant, medium viscosity, self-extinguishing flame retardant, low stress, thermally
conductive epoxy casting resin system.
•
This material is UL 94V0 rated and was designed to meet the physical security
requirements of FIPS 140-2, and FIPS140-3 for an encapsulating material.
•
The materials inherent nature offers excellent Tin-whisker mitigation properties. It provides
very good resistance to water, salt spray, inorganic acids, bases and most organic solvents.
•
The material is intended for use in both indoor and outdoor environments.

EMI RFI Shielding

Other solutions apply a conductive coating over the CCA itself effectively
creating a Faraday Cage around the CCA eliminating the need for an
enclosure. (This requires a pre-coating to seal the assembly and prevent
shorts.)

Wrapping an assembly in a conductive material and then potting around it
also creates the RF barrier and provides structural support as well.
