EMI ESSENTIALS
EMI INTRODUCTION
Overview of EMC/RFI Issues
The phenomenon of electromagnetic interference (EMI) is familiar to virtually everyone, even if they do not
understand the underlying principles. Most people have witnessed firsthand the effects of interference.
To control EMI, government organizations, such as the FCC, CSA, and EEC, mandate that manufacturers may
not design, produce or sell electronic equipment that jams the public broadcast services. In other instances,
however, EMI can constitute more than a mere nuisance. The military and medical communities, for example,
require trouble-free operation of their electronic equipment in adverse electromagnetic environments since
malfunctions could jeopardize missions and personnel. The European Union’s EMC directive also mandates
that “the apparatus has an adequate level of intrinsic immunity to electromagnetic disturbance to enable it
to operate as intended”.
EMC Design of High Speed Systems
The interference and susceptibility (immunity) effects of electronic apparatus are created by time-variant
electromagnetic fields which may be propagated along a conducting medium or by radiation through space.
Because the source of the conducted and radiated interference energy levels may be related, a coordinated
systems design effort is required to reduce these effects.
A design program for an equipment item that must meet both an emission and an immunity requirement
consists of:
• Suppression: Reducing the interference at its source.
• Isolation: Isolating the offending circuits by filtering, grounding and shielding.
• Desensitization: Increasing the immunity of any susceptible circuits.
These three steps should be carried on throughout the entire equipment design and implemented as early
as possible within the design program.
Effects of Logic Speed
The trend in today’s electronic devices is faster, smaller, and digital rather than analog. Most equipment
(95%) of today contains digital circuits. Today’s digital designer must create a circuit board that has the
lowest possible EMI, combined with the highest possible operating/processing speeds. Design of the PCB
is the most critical EMC influencing factor for any system, since virtually all active devices are located on
the board. It is the changing current (accelerated electron movement) produced by the active devices that
result in EMI.
Design Approaches
There are two approaches that can be used to reduce the emission from the PC board. The first approach is
to operate the circuit at the slowest speeds consistent with the functionality of the system, lay out the PCB
with the smallest possible loop areas (especially the high speed devices), and insert suppression components
such as filters, ferrite beads, and bypass capacitors into the circuit to reduce its bandwidth. These techniques
will result in a desired decrease in the high frequency harmonic amplitudes and circuit bandwidth and a
corresponding undesired decrease in both the operating speed and system reliability. The use of slower
speeds with reduced bandwidth will help to desensitize the circuit to external susceptibility fields.
The second is to use shielding. Shielding is the only non-invasive suppression technique. Since the shielding
is not inserted into the circuit, it does not affect the high frequency operating speed of the system, nor does
it affect the operation of the system should changes be made to the design in the future. In addition,
shielding does not create timing problems and waveform distortion; it does not decrease system reliability;
and it reduces crosstalk. Plus, shielding works for both emission suppression as well as susceptibility
(immunity) problems.
2
Even with the overall advantages of shielding, the most cost-effective approach is to use a combination
of circuit suppression/hardening and shielding.

INTRODUCTION TO ELECTRICALLY
CONDUCTIVE ELASTOMERS
OVERVIEW
ELECTROSEAL™ GASKET INTRODUCTION
The electrically conductive elastomers are based on dispersed
particles in elastomers, oriented wire in solid or sponge
elastomers, impregnated wire mesh screens or expanded metals.
They provide highly conductive, yet resilient gasketing materials
for EMI sealing as well as pressure and environmental sealing.
Conductive elastomer gaskets are EMI shielding and sealing
devices made from highly conductive, mechanically resilient and
conformable vulcanized elastomers. They are available in the
following types:
Conductive elastomers are used for shielding electronic
enclosures against electromagnetic interference (EMI). Usually,
the shielding system consists of a conductive gasket sandwiched
between a metal housing and lid. The primary function of these
gaskets is to provide sufficient electrical conductivity across
the enclosure/gasket/lid junction to meet grounding and EMI
shielding requirements, as well as prevent intrusion of the fluids
into the electrical components.
Laird offers conductive elastomers in the following forms:
1. ElectroSeal dispersed filler particles in elastomers
2. ElectroMet oriented wire in solid and sponge elastomers,
and impregnated wire mesh and expanded metals
1.
2.
3.
4.
5.
6.
Flat gaskets or die-cuts
Molded shapes such as O-rings or intricate parts
Extruded profiles or strips
Vulcanized-to-metal covers or flanges
Co-molded or reinforced seals
Form-in-place gaskets
When any two flat, but rigid surfaces are brought together,
slight surface irregularities on each surface prevent them from
meeting completely at all points. These irregularities may be
extremely minute, yet may provide a leakage path for gas or
liquid under pressure, and for high frequency electromagnetic
energy. This problem remains in flange sealing even when very
high closure force is applied.
However, when a gasket fabricated of resilient material is
installed between the mating surfaces, and even minimal
closure pressure is applied, the resilient gasket conforms to the
irregularities in both mating surfaces. As a result, all surface
imperfections and potential leak paths across the joint area
are sealed completely against pneumatic and fluid pressure or
penetration by environmental gases. If the gasket is conductive
as well as resilient, with conductive matrix distributed
throughout its total volume in mesh or particle form, the joint
can be additionally sealed against penetration by, or exit of,
electromagnetic energy.

CASE STUDY
EXAMPLE
A Telecommunication customer A is looking for a gasket for RRU chassis. The chassis will be made of Aluminum by casting.
There is an existing design including groove. Groove dimension is as follows. The customer is looking for an electromagnetic
shielding larger than 50 dB for the chassis. And high reliability is required considering RRU unit will be exposed in open air
and sustain various weather condition such as snow, rain, fog, etc.
Select elastomer base
Selection Process
Conclusion
Take reference of Table 1
Silicone
All the three bases can meet resistance requirement
against weather, but silicone is the most cost effective
one. And also best on availability and processibility.
Select filler system
"Take reference of Table 3 for galvanic performance and
Material Selection Table 6
1. Ag/Al filler would be most compatible with casting
aluminum.
2. Ni/Graphite is a cost effective solution but still acceptable. Can be a candidate for future cost/performance
comparison.
3. Better use a hybrid design considering high reliability
requirement.
4. Both filler system can provide high shielding. But final
performance would rely also on final design."
"Hybrid (NCE+ECE),
ECE81(Ag/Al)
or ECE93(Ni/Graphite) "
Closure force
Medium closure force required because the RRU unit need
to sustain water flush without high pressure
Hollow cross section
Is there an existing design?
(part/groove/flange/interface)
There is an existing groove design. But can not find
corresponding groove recommendation in brochure.
Would need a design on gasket.
Contact Laird FAE for it.
What's the shape?
Existing groove design is rectangle shaped. A standard
double D co-extrusion might work
Decide dimension
"Filling percentage >90% to bear water flush
Compression >=25% considering large coplanarity of
chassis and cover
Final FEA possible to confirm the design
Co-extrusion required because the total length is 1600
mm"
How to mount the gasket?
Would need a PSA to hold the strip in groove
Design Shape & Dimension
Double D co-extrusion or
custom design
But a friction fit design can also be done for easy assembly and cost saving. Example

EMI ESSENTIALS
Q-ZORB ® 2000 HF (HIGH FREQUENCY)
SURFACE WAVE ABSORBERS
Q-Zorb® 2000 HF surface wave absorbers are thin,
magnetically loaded elastomeric sheets designed to
provide attenuation at high angles of incidence for surface
wave attenuation. They are nominally manufactured in
the thickness range of 0.015" to 0.125" (0,4 mm to 3,2
mm). Q-Zorb® 2000 is silicone-based, meets the UL V0
fire retardant requirement and is RoHS compliant. Laird
can provide the material die-cut and with a pressuresensitive adhesive for ease of installations. Sheets are
offered in nominal sizes of 24" x 24" (609,6 mm x 609,6
mm), although custom sizes and molded components are
available.
APPLICATIONS
FIGURE 1.
FIGURE 3.
The material can be used inside of microwave housings
to reduce internal resonance and to lower the "Q" of
the microwave cavity. They are also effective in isolating
antennas from ground plane reflections. Q-Zorb® can
be used with board-level shielding and other types of
EMI shielding to enhance the shielding effectiveness at
frequencies from 2-40 GHz.

EMI ESSENTIALS
Q-ZORB ® 3000 HP (HIGH PERMEABILITY)
ABSORBERS CA-19
Q-Zorb 3000 HP product line utilizes special shaped
magnetic fillers in a polymeric binder to produce thin
sheets with excellent low frequency performance. The
product has very high permeabilities along with low
frequency magnetic loss. This allows relatively thin
sheets of material to perform at frequencies below 2
GHz. CA 19 comes in thickness ranges of .006” .15
mm to .020” .5 mm. and is very flexible. The product is
available in rolls 13” wide and any length available. It
can be die cut into specific shapes and is supplied with a
pressure sensitive adhesive backing for ease of use.
APPLICATIONS
Q-Zorb 3000 is used in situations where low frequency
(< 2 GHz) noise problems are occurring. Some
applications include:
• Die cut components placed in microwave cavities

RFRET 4000 RETICULATED
FOAM ABSORBERS
RFRET 4000 is a reticulated foam absorber. Reticulated
foam is an urethane-based foam with a well-defined
open-cell structure. The cell size can be chosen to
optimize penetration of the conductive coating to
which it is adhered. Laird uses two separate processes
to produce its reticulated foam absorber. This unique
spray process applies a coating that is graded through
the thickness of the foam. The grading of the coating also
produces an electrical grading that results in a material with
excellent broadband reflectivity reduction.
APPLICATIONS
RFRET broadband foam is commonly used around
antennas to provide isolation or side lobe reduction.
It can be die-cut into components for EMI reduction
inside microwave cavities and is used to manufacture
antenna hats and test boxes. It can be encapsulated
into a textile cover for use outdoors and fabricated into
blankets, covers and other components. Recently, it has
been used for a combination air/EMI filter in networking
equipment. The product can be made UL 94 HF1 for such
applications.

RFLS 5000 SINGLE LAYER
"LOSSY" FOAM ABSORBERS
APPLICATIONS
RFLS 5000 is a series of single layer "lossy" sheets
produced by dipping lightweight open-celled urethane
foam into a resistive solution. The end product is a
uniform, lightweight, loaded sheet material with a
specified insertion loss at a given frequency. RFLS
offers the lowest cost in microwave absorber products.
Thickness of the sheets range from 0.125" to 1.5"
(3,2 mm to 38,1 mm) and are generally 24" x 24"
(609,6 mm x 609,6 mm). Custom sizes and components
can be fabricated. The insertion loss of the product is
measured in an insertion tunnel over the 2 to 18 GHz
frequency range. Specifications are generally given
at 3 or 10 GHz. The material can be die-cut into
components and supplied with a pressure-sensitive
adhesive for ease of application.

ANALYSIS, TEST AND
PROTOTYPE DEVELOPMENT
ABSORBER BOARD-LEVEL SHIELDING (ABLS)
FIGURE 1.
Increasing use of printed circuit boards in complex electronics
requires unique shielding solutions. Laird has developed a near
field measurement to accurately determine the effectiveness of
board-level shielding. Several Laird board-level shields have been
characterized using this technique.
Laird has further enhanced performance at greater than 2 GHz by
adding a microwave absorber to the board-level shield. Further
work has been completed on FlomericsTM FLO-EMC to analytically
investigate board-level shields performance improvement using
absorbers at high frequency.
THERMALLY CONDUCTIVE ABSORBERS –
COOL-ZORB
VBROP can optimize absorber performance at various frequencies
and angles of incidence.
Laird is developing thermally conductive microwave absorbing
materials. These can be used as thermal pads between chips and
heatsinks, allowing conduction of heat and dissipation of EMI.
Initial testing and modeling has shown this to be an effective
solution to heat sink radiation from noisy chips.
MU EPSILON MEASUREMENT CAPABILITIES
Laird has a network analyzer to make amplitude and phase
measurements from 130 MHz to 20 GHz. Laird also has a
reflectivity arch, transmission tunnel and a variety of coaxial,
wave-guide and other test equipment to determine intrinsic
electrical properties of absorber materials. This ability has enabled
Laird to build a database that customers can use to design new
absorbers and analyze their performance in different situations.
Absorber Board-level Shield (ABLS)
ANALYTICAL SOFTWARE VBROP
VBROP is a versatile Windows® 95/98/NT-based optimizer of
multi-layered stacks for reflection or maximum transmission at
specified frequencies, angle of incidence and polarization. The
visual basic front-end makes the software extremely user friendly,
with interactive analysis of layer properties versus performance. It is
useful for the design, optimization and detailed performance analysis
of RAM, RAS, radomes and microwave windows.
