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 effect the high frequency operating speed of the system, nor does
it effect 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.

BOARD LEVEL SHIELDS
EZ PEEL ™
PATENTED SHIELDS ARE SCORED TO ALLOW PEEL-OFF WHEN ACCESS IS NEEDED
These patented shields have a solid top, scored to allow peel-off when access to board level components within
the shield is required.
The peel-off feature prevents damage to the board and components by eliminating the need for labor intensive
de-soldering, which can often result in increased scrap. Peeling off the cover is accomplished by using a small
starter hole for simple removal. This hand operation requires minimal force using a hook scriber or tweezers.
After repair, replacement or adjustment of internal components, the shield can be resealed using a replacement
cover. Laird Technologies offers two replacement cover options: a snap-in cover and a dish cover.
The snap-in cover utilizes a lance and hole design. The replacement cover snaps into place and locks into a lance
feature on the frame of the original shield.
The other option is a dish cover that gets soldered into place on the board. The dish shape allows for self-location
of the cover for soldering.
EZ Peel board level shields can be packaged in tape and reel formats for easy SMT installation using conventional
pick-and-place equipment. The four standard sizes are also available without the EZ Peel (scored) feature.
Features and Benefits:
•Easy removal of scored cover area
•Only requires 1.5 lbs force for
cover removal
•Simple replacement technique
for cover
•Use on surface mount or
through-hole applications
•Shield retains all physical
properties after PCMCIA/JEIDA
testing for shock, bending, torque,
drop and vibration
•CRS 1008/1010 (tin plated)
for solderability
RIGID CORNER
The rigid corner board-level shield incorporates a corner design that optimizes component rigidity for increased part and printed circuit board
(PCB) firmness. As PCB designers are increasingly using thinner substrates, a rigid frame reinforces the assembly, thereby improving overall
ruggedness and performance. The shield has improved solder joint reliability and resistance to solder joint fracture, especially in drop testing
performance with thin PCBs. Several standard Laird Technologies EMI style parts including single-piece, two-piece, and multi-compartmental
board-level shields use this new rigid corner design, along with availability in custom sizes as well.
The rigid corner shield is stronger and more robust than traditional formed shields, which results in coplanarity improvement of the solder
castellations. The shield can tolerate more deflection (i.e., more handling) without plastic deformation. Elimination of drawn flange reduces
the space needed on the PCB for shielding trace width by potentially ~0.3 mm, allowing for the shield to be more closely placed on the PCB.
Elimination of draft allows for more undershield space and improved component clearance.
The partially drawn corner is located near the top portion the shield, resulting in improved torsional rigidity with no drawn lip and no draft.
For parts over 2 mm, the corner is both drawn and formed with an interlocking multi-radius corner, which provides superior EMI shielding
effectiveness. The interlocking corner can be meshed and closed in during the forming and drawing process for additional improved rigidity
for parts taller than 2 mm. For parts under 2 mm, the entire corner is drawn without an interlocking corner.

BOARD LEVEL SHIELDS
INTRODUCTION
The complexities of today's electronics pose several design challenges.
Resolving EMI needs to be balanced with space, weight and production
restraints. When designing a custom shielding solution, beginning in the
earliest stages of the application design allows effective elimination of EMI
while meeting all specifications.
Laird Technologies board level shielding experts work through all phases of
development. From design, rapid prototyping and pre-production through
production and automated packaging, Laird Technologies has the experience
to help speed a product to market and stay within budget.
To increase manufacturing throughout and reduce costs, Laird Technologies
has developed a proprietary in-line production process that includes part
formation, wash, assembly, inspection and automated packaging.
By integrating quality processes, board level shield quality and performance
is ensured from design stage through final packaging. One process is the
automated co-planarity inspection system. Laird Technologies replicates the
customer application by measuring shields in the same plane as the printed
circuit board. This is accomplished without "securing" or "touching" shields,
which could throw off measurement and/or deform parts. Laird Technologies
measures shields immediately prior to placement into carrier tape at speeds
that match automation packing.
Shield base materials include our exclusive Shield-LiteTM, CRS 1008/1010,
beryllium copper alloys, nickel-silver alloys, copper-based alloys and spring
steels. All shields are fully solderable.
ONE-PIECE SHIELD DESIGN
LOW COST/EXCELLENT EFFECTIVENESS
Custom surface mount shields are available in both one-piece and
two-piece designs. One-piece shields provide six sides of protection,
with the sixth side being the board itself. One-piece designs offer
economical shielding alternatives where access to covered components for
repair is not necessary.
TWO-PIECE SHIELD DESIGN
QUICK, EASY REPAIR AND INSPECTION OF COVERED
COMPONENTS
Two-piece board level shields offer users the flexibility to inspect or repair
shielded components without having to risk board damage by removing
the entire shield. Covers snap on and off with ease, making repairs quicker
and easier, and reducing board re-work. Two-piece shields are available
pre-assembled or unassembled. Large locking dimples snap into slots on
covers to provide mechanical retention force. Smaller grounding dimples
provide electrical grounding for proper shielding and to prevent rattle.
Two-piece shields survive drop, shock and no-rattle tests. Here are critical
test results:
• Able to withstand acceleration of 4g from 10 Hz to 2000 Hz for three hours in each of three planes as per SAE J1455
• Pass EN 50 155 for railway electrical equipment including vibration test of 30g from 5 Hz to 200 Hz in 3 directions and a shock test with 500 m/s for 11/ms
• Pass standard telecommunications drop tests [6 faces, dropped 1 meter onto concrete floor]
Notice: The data set forth in all text, tables, charts, graphs and figures herein are based on samples tested and are
not guaranteed for all samples or applications. Such data are intended as guides and do not reflect product
specification for any specific part. Material properties are for reference only. Product testing by purchaser is recommended to
confirm. Laird Technologies assumes no liability for product failure unless specifically stated in writing.

Series 97-2100
MULTI-COMPARTMENTAL SHIELD DESIGN
SHIELD MULTIPLE CIRCUIT GROUPS SAVE PCB SPACE AND PRODUCTION
TIME
Multi-compartmental shields feature internal dividing walls of one material
thickness and meet all on-board shield requirements for FCC, VDE, CISPR
and CE. These shields are available in two-piece designs, either assembled
or unassembled. Our unassembled versions allow for automatic optical
inspection prior to cover placement. As in all our shielding offerings,
Laird Technologies proprietary process for 100% automatic optical
inspection verifies co-planarity including inner walls.
DRAWN BOARD LEVEL SHIELDS
SEAMLESS CORNERS ADDRESS HIGH-FREQUENCY LEAKAGE
As microprocessor speeds continue to increase, so does the potential for EMI
leakage through the smallest apertures in board level shields. Laird Technologies
drawn board level shields are designed to provide additional near-field and
far-field circuit isolation (attenuation) at higher frequencies by eliminating the
apertures found in the corners of traditional board level solutions. Drawn board
level shields utilize small ground trace sizes, thereby preserving space on the
circuit board.
• Solid corner designs when additional circuit isolation (attenuation) is required at higher frequencies
• Available in custom heights up to .250" (6,4 mm) with length and width
dimensions from .300" (7,6 mm) to 2.0" (50,8 mm)
• Tape and reel packaging provides an economical and automated SMT attachment method
• Available in cold rolled steel, brass, stainless steel and nickel silver
• Molded Compartment Shields and Form-In-Place elastomers can be
combined with drawn board level shields to achieve shielding of
multiple components with a single part
• Available with an EZ Peel scored cover feature; allows for easy top

applications, such as flame-sprayed surfaces, 0.010 in. (0.254 mm) thick
nonconductive tape is recommended. Optional conductive tape is also available.
Contact a sales department representative for additional ordering information.
SLOT MOUNT
Slot mounted parts are easily installed using slots where bi-directional movement is required.
Simply install part into one slot and snap it into the second slot or over the edge of the frame.
CLIP-ON MOUNTING
ADHESIVE MOUNTING
Sticky Fingers® is an instant, pressure-sensitive adhesive bonding system, ideal for all-purpose
contact strips for metal cabinets and electronic enclosures, and is unaffected by temperatures
from -67 to +250°F (-55 to +121°C).
Clip-on gaskets hold firmly in place due to their own spring characteristics.
Simply push the strips onto the edge or flange of the door or enclosure.
Also available are clip-on gaskets with either “T” or “D” lances.
Simply follow these four easy steps:
TAPE TRACK MOUNTING
1. Remove all grease and oily residue with solvent. Smooth the mounting surface with emery
cloth.
Stainless Steel mounting track with PSA (pressure sensitive adhesive) is available
on the Symmetrical Slotted Series and Slot Mount Series.
2. Peel off protective paper backing.
WELDING
3. Place gasket in correct position. (See mounting methods diagrams A through E.) Press firmly
to ensure a good adhesive bond. Avoid repositioning, which might impair the effectiveness of
the adhesive or may bend or kink the strip.
Welded mounting requires simple, traditional welding techniques.
NOTE: On items where fingers cover the solid portion of the gasket, pressure may be applied
16 by inserting a mandrel in the strip and pressing down. For contact strips with Magnefil® insert,
simply press down on the fingers.

SOLDERING
Solder mounting requires normal low temperature soldering techniques,
including cleaning and fluxing of parts with common copper flux materials.

VARIABLE SLOT MOUNT
Laird Technologies introduces Variable Slot Mount shielding,
which eliminates the use of long slots while still utilizing the easy
installation method of slot mount shielding. Fingers are removed
from the strip in areas where a mounting slot is not present.
The Variable Slot Mount shielding strips can be customized to any
patterned series of slots.
• Easy and cost-effective installation since fasteners and adhesives
are not required
• Improved shielding effectiveness compared to traditional slot
mount series through elimination of long slots in host material
• Slot mounting feature can be varied to accommodate different
lengths and hole mounting patterns (see figure 2)
• Three and five pitch segments ideal for grounding applications
• Bi-directional wiping and compression action to accommodate a
wide variety of designs
• Available in standard (77-Series) and UltraSoft® (78-Series low
compression versions)
• Ability to retrofit equipment when higher clock speeds limit current
slot mount product without changing slot size or location
• One piece construction eliminates handling individual pieces,
thereby shortening installation time
• Ideal for grounding and shielding in the following electronic
enclosure applications:

WITH STICKY FINGERS
Series 97-951/954/957 are low compression, adhesivemounted beryllium copper shielding strips. Designed as
a continuous band, the strip is slotted to permit spring
contact throughout its length. A wide radius profile creates
the greatest contact for maximum conductivity with minimum compression
requirements. As with all Sticky Fingers shielding strips, a self-adhesive tape
makes mounting easy and secure. All are available in your choice of finishes,
see page 17.

SOLID TOP (S 3 ) SYMMETRICAL SLOTTED
SHIELDING GASKET
Laird Technologies offers their Solid Top Symmetrical Slotted Shielding
Gaskets. This product is uniquely designed for those applications
where a lid or cover is closed using a sliding motion to complete
the closure. The solid top design allows the cover to slide either
perpendicularly or parallel to the fingerstock without snagging or
damaging the gasket.
• Solid top provides an additional 10 dB of shielding effectiveness
• Offered in both rivet mount and tape mount versions
• Available with two types of rivets
• Generous radii provide maximum conductivity with minimum
compression forces
• Parts can be modified and/or cut to any specific length
• For longitudinal sliding applications, a retention clip is
recommended for secure mounting
• Available in standard or UltraSoft® (part numbers beginning with
-98) versions

These versatile gaskets are made from highperformance beryllium copper with Sticky Fingers®
self-adhesive backing. They provide an extremely
tight, instant bond and are ideal as an all-purpose
contact strip for metal cabinets and electronic
enclosures, particularly where space is critical.
Magnetic field shielding effectiveness of these strips has been proven
to be > 46 dB for a 14 kHz plane wave and 108 dB for a 10 GHz
plane wave. When tested per MIL-STD-285 for electromagnetic
shielding, these strips showed superior performance under minimum
compression. They proved to be especially effective where variations
exist in the space to be shielded and in applications that require high
shielding performance despite frequent opening and closing of the
cabinet.

This series from Laird Technologies is designed for use where high
temperature or other design considerations preclude the use of
adhesive-mounted gasketing. Yet it provides the same shielding
characteristics and effectiveness as on Sticky Fingers® mounted
series. Clip-On Gaskets offer shielding effectiveness >100 dB for
100 MHz plane wave. All are available in your choice of finishes,
see page 17.
These 97-Series products are also available in UltraSoft® low
compression force 98-Series.
SNAP-TITE® WITH “D” LANCE
This configuration has been designed specifically to provide outstanding holding power. “D” lances snap into drilled or punched
holes in the mounting surface to create a strong omnidirectional
grip with excellent conductivity.

CLIP-ON PERPENDICULAR SHIELDING
This product offers a clip-on design that permits shielding to a
perpendicular surface.
• Finger design allows for continuous contact across the length of
the strip
• Clip-on design is ideal where high temperature or other design
considerations preclude the use of adhesive-mounted gasketing
• “D” lance design provides excellent retention of gasket and
allows for a strong omnidirectional grip
• Supplied in a wide variety of plating finishes, see page 17
• Shielding effectiveness of > 80 dB for a 10 MHz plane wave.
• These 97-Series products are also available in UltraSoft® low
compression force 98-Series.

Laird Technologies offers the GBIC Shield for reducing emissions from GBIC
(GigaBit Interface Converter) fiber optic transceivers. Fiber optic transceivers
can be a troublesome source of EMI because they emit high-frequency signals
and are located adjacent to large apertures in the enclosure. The GBIC Fiber
Optic Shield assembly reduces the radiated emissions from the transceivers
by conducting interference current away from the transceiver and onto the
enclosure surface.

GAIN MAXIMUM ELECTRICAL AND CARRYING PERFORMANCE
From concept to placement, Laird Technologies has the expertise to deliver
custom precision surface mount contacts. Using the latest computer
simulation techniques, Laird Technologies provides properly designed contacts
that ground, carry current and signals, and interconnect boards and devices.
Laird Technologies uses basic geometric parameters (length, width,
uncompressed height, compressed height, contact force) to conduct
Finite Element Analysis (FEA) on your prospective design.
With the FEA results, we can then identify the best design to optimize a
product's operational performance. Features are incorporated to provide for
placement and soldering of the contact onto the circuit board.
Laird Technologies offers a wide range of plating options to allow for
maximum electrical current carrying performance.
^
Automated packaging allows for complex and small designs with lower
installed costs.
Contact base materials include beryllium copper, phosphor bronze, nickel
and stainless steel. All contacts are fully solderable as required.

EMI ESSENTIALS
METALS GALVANIC COMPATIBILITY
CHART
For harsh environments (presence of fair to good ionic
conductors), all metals in contact with each other should be no
more than one level of the chart apart to minimize corrosion. This
is shown by the dark blue regions of the plating bar chart under
specific platings. Outdoor applications, high humidity and salt air
fall into this category.
For normal environments (storage in warehouses or
non-temperature/humidity-controlled environments, etc.), the
difference between dissimilar metals should not exceed 0.25 volts
(5 chart levels counting the origin). This is shown by thelight blue
regions of the chart under specific platings.

For office environments (temperature and humidity controlled), 0.5
volts can be tolerated(10 chart levels counting the origin). This is
shown by the dark gray regions under specific platings. Caution
should be maintained when deciding that your application is
temperature and humidity controlled. Many devices intended for
use in office environments are storedin warehouses for extended
periods of time before and in between use.
These are general guidelines which apply under most circumstances, but
corrosion is a very complex subject whose details could not possibly fit in
this space. If you are not sure which metals are compatible, please feel free
to contact Laird Technologies and talk to our corrosion experts.

COMBINING EMI INNOVATION
AND COST EFFICIENCY
Laird Technologies patented MaxAir vent panel product
line provides an innovative cost effective approach for
providing increased airflow and EMI protection for
telecommunications hardware equipment such as fans and
server racks.
This metallized polycarbonate honeycomb material
provides a rigid medium eliminating the need for costly
frame designs. This frameless design allows greater airflow
through the entire honeycomb surface and ease of
installation through its press-to-fit assembly. The MaxAir
vent panel provides greater durability and flexibility than
traditional aluminum vent panels.
Varying densities of material are available to meet specific
levels of rigidity requirements. The honeycomb cell size can
be 0.125 in (3,18mm) or 0.250 in (6,35mm) in standard
thicknesses of 0.250 in (6,35mm) and 0.500 in (12,70mm).

FABRIC-OVER FOAM
METALLIZED SHIELDING GASKETS
Laird Technologies is a fully integrated manufacturer of profile
and Input/Output (I/O) EMI shielding gaskets. The metallized
Fabric-Over-Foam product line has been expanded greatly due to
our committed efforts in new product development and meeting
or surpassing regulatory requirements.
This catalog is designed to provide helpful information to
engineers on our expanded product line. In this section, you will
find benefits for Fabric-Over-Foam gaskets, material options and
an extensive list of profile and I/O sizes and configurations.
Laird Technologies specializes in quick turnaround of custom
shapes and sizes of EMI shielding gaskets. If you don’t find
exactly what you need, our engineers will help you design the
right solution to your shielding problem.
A sampling for standard profiles are shown; custom
configurations and sizes can be designed to meet your specific
requirements. Profiles are shown in ascending order by height
(starting on page 58).

The recommended operating compression for Fabric-Over-Foam
EMI Gaskets will vary depending on the shape and size of the
particular gasket.
Typically, D-Shaped, Rectangular Shaped, and Square Shaped
Fabric-Over-Foam EMI Gaskets should be compressed between
30% and 50% of the foam height.
Similarly, C-Shaped Fabric-Over-Foam EMI Gaskets should
typically be compressed between 50% and 75% of the
gasket height.
Force Displacement Resistance (FDR) graphs are available
upon request. Please contact engineering department at Laird
Technologies when unsure.
Certain combinations of materials may not be available for all
Profiles or I/Os. Please consult the Engineering Department at
Laird Technologies when unsure.

BASIC I/O GASKET DESIGN
1. Space between required cutouts should match or exceed 0.060" (1,5 mm).
2. D
istance from the edge of a cutout should be at least 0.060" (1,5 mm)
from the edge of the gasket. In most cases, a slot can be used in place
of a hole that is positioned too close to the gasket edge.
3. All cutouts and locations are designed customer specifications.
4. P ressure Sensitive Adhesive (PSA) and Extended Release Liner (ERL) can be
applied in parallel with the long edge of the gasket.
The recommended operating compression for Fabric-Over-Foam EMI gaskets
will vary depending on the shape and size of the particular gasket. Typically,
I/O gaskets should be compressed between 30% and 50% of the foam height.

KNITTED CONDUCTIVE GASKETS
EXCELLENT VERSATILE SHIELDING PERFORMANCE WITH GREAT VARIETY
Wire mesh gaskets are a very versatile and proven style of shielding. Wire mesh gaskets have a great variety of uses and there are several
popular types to choose from depending on shielding or environmental requirements. Knitted gaskets can be made from a variety of metal
wires, including monel, tin plated-copper clad-steel or aluminum. Cost-effective for low cycling applications with high shielding effectiveness
over a broad frequency range. Available in a wide variety of sizes and shapes, the knit construction provides long lasting resiliency with
versatile mounting options. Available with elastomer gasket for moisture and dust sealing.
Popular product lines include the ElectroNit™ All Mesh, which is the most economical gasket for low cycling applications and is designed to
offer the highest levels of attenuation. UltraSoft™ Knit offers close-knit stitch of the metallized nylon provides a highly effective EMI shield,

ELECTROMESH ® TAPE
Laird Technologies ElectroMesh tape has a double layered strip of knitted
wire mesh to provide effective EMI shielding and grounding for electrical and
electronic cable assemblies.
It is particularly useful in applications where the need for EMI protection is
determined after cable assembly is complete and standard braided cable
jackets cannot be used. The flexible structure of the ElectroMesh Tape permits
it to conform to irregular surfaces and contours during the wrapping process.
• Tin plating for excellent solderability
• Useful in both shielding and grounding applications forstatic discharge
• Tin plated copper clad steel wire provides greater strength and
performance than other tape materials
• Knit loop structure provides uniform coverage without any wrinkles or
creases
• Available in other alloys and wire dimensions
• Supplied in 50 ft. (15,2 m) rolls. (Note: When determining quantity needed,
50% overlap is recommended.)
• Mesh tape also available in Monel® (material code 42); BeCu (material
code 40); Aluminum (material code 43); and Stainless Steel (material code
46)
• Other alloys available upon request
ElectroMesh tape is 0.020 (0,5) thick. It is available in tin plated copper clad
steel ASTM-B-250, with a diameter of 0.005 (0,1) and with 10–12 openings
per inch.

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 Technologies 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 Technologies 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

But a friction fit design can also be done for easy assembly and cost saving. Example

ELECTROMET™ ORIENTED WIRE
ElectroMet oriented wire gaskets are EMI shielding and sealing
composites. Monel® or aluminum wires embedded in the
elastomer and oriented perpendicular to the mating surfaces
provide the EMI sealing. Solid or sponge silicone provides the
weather sealing; however, solid silicone weather seals are
recommended for high-pressure applications.
Silicone based oriented wire composites are capable of
withstanding temperature ranges from –70°F to 500°F
(–56°C to 260°C). Oriented wire materials are available in sheet
or strip form with a minimum thickness of 0.032 in. (0,8 mm).
Material specifications and information for standard sheets and
strips are provided in Tables 1 through 3.

ELECTROCOAT™
ElectroCoat is a thin, flexible surface coating consisting of a
silver-filled silicone elastomer. The versatile coating can be easily
applied to die-cut or molded foams for both gasket and nongasket applications. It can also be applied to molded or extruded
elastomers, other polymers, and a wide range of other materials.
•Excellent shielding effectiveness — greater than 90 dB
measured by transfer impedance
•Solid, continuous, conductive coating over the entire gasket
surface, including the inner die-cut surfaces of foam gaskets
•Coated foam gaskets have very low compression force
•Exceptionally wide compression range from 10% to 70%
deflection to accommodate uneven gaps in enclosure
housings
•Flexible coating withstands gasket compression with no
decrease in shielding effectiveness after 1000 cycles of 40%
compression
•Extruded profiles shown on pages 87-92 are available with
neoprene core.

AUTOMATED FORM-IN-PLACE
EMI GASKET TECHNOLOGIES
INTRODUCTION
Laird Technologies form-in-place is an automated system
for dispensing conductive elastomer EMI shielding and
grounding gaskets onto metal or plastic substrates. Formin-place is particularly well suited for cellular phones, PDAs,
PC cards, telecom base stations, radios, and many other
compartmentalized cast or plastic enclosures and packaged
electronic assemblies.
Utilizing programmable 3-axis CNC dispensing equipment,
the compound is dispensed accurately onto the substrate and
creates a secure bond during the curing process. The repeatable
computer-controlled dispensing pattern insures consistency
between parts and rapid part program changes. In addition, it
supports all levels of volume – from prototyping to high-volume
electronic component production – via the use of one or multiple
dispensing heads. The system is programmed to apply custom
gasket configurations onto parts, to form multiple levels on the
part, and on slopes up to approximately 70°.
Laird Technologies RXP compounds are Room Temperature
Vulcanizing (RTV) elastomers and HXP compounds are High
Temperature Vulcanizing (HTV) elastomers, both filled with
proprietary conductive particles. Dispensed gasket beads of RXP
compounds may be handled in 3 hours, and are cured in 24 hours,
under conditions of standard temperature and 50% Relative
Humidity. Dispensed gasket beads of HXP compounds can be
handled after the materials are cured in an oven. The compounds
have a working compression range from 10% to 50% of the
gasket height, with a recommended design compression of 30%
against a mechanical compression stop. Our product is designed
to support low closure forces and is compatible with plastic,
metal, and plated or chromate finished substrates.
The required force to compress a given bead is a function of the
compound and the gasket size; i.e. smaller gaskets require less
force than larger gaskets. Please refer to our technical data for
details. Gaskets are dispensed on substrates within a placement
tolerance of ± 0.001 inches and gasket cross-sectional tolerances
from ± 0.003 to 0.007 inches. Refer to Table 1 on page 104 for
typical gasket dimensions and tolerances. As a normal course of
equipment operations, starting points and termination ends of the
gaskets will have profiles that are approximately 25% larger than
the running gaskets.
TYPICAL APPLICATION FOR FORM-IN-PLACE GASKETS:
Automated dispensing of compound is
controlled by sophisticated computer software,
which is user-friendly and easy to work with.
FORM-IN-PLACE GASKETING
FEATURES AND BENEFITS
• Form-in-place gasketing offers a total cost savings in the
form of reduced raw materials, labor or assembly time
• Room temperature cure gasketing materials eliminate the
need for costly heat curing systems, allowing the use of
inexpensive plastic or metal substrates
• Single-component compounds eliminate the need for mixing
ingredients, thereby shortening production cycles and
eliminating related waste
• Easy to program operating system allows for quick part-topart change-over, minimal tooling investment for new designs,
and prototype development in 24 to 48 hours
• High shielding effectiveness: 85–100 dB up to 10 GHz
• The dispensing system supports prototyping and high volume
production schedules in a space saving 4’ x 3’ [12 sq. ft.] (1,2
m x 0,9 m [1,1 sq. m]) footprint
• Form-in-place gaskets provide more critical packaging space
for board level components and smaller package dimensions
• Excellent adhesion on a wide variety of metal and plastic
substrates including:
- aluminum and other casting alloys
- stainless steel
- nickel copper plating (on plastics)
- copper, silver, and nickel filled paint (on plastics)
• Low compression force makes SN compounds an
excellent selection where the mating surfaces lack
mechanical stiffness

DESIGN GUIDE FOR
COMMERCIAL MICROWAVE ABSORBERS
Microwave absorbers have been used in military applications
for several decades. They have been traditionally used for EMI
reduction, antenna pattern shaping and radar cross reduction.
More recently with the rise of wireless electronics and the
movement to higher frequencies microwave absorbers or “noise
suppression sheets” (NSS) are used to reduce electromagnetic
interference (EMI) inside of the wireless electronics assemblies.
Two types of NSS are used for these types of applications.
They are described below:
MAGNETIC ABSORBERS
ABSORBER APPLICATIONS
Electronic operating at high frequencies can have problems with
emission of high frequency noise. Once put inside an enclosure,
the energy will add in phase at certain frequencies to cause
resonances which will hinder the performance of the device.
A good example of this phenomenon is seen in Figure 1.
The amplifier was measured in the condition shown and
subsequently remeasured inside of its enclosure. When put inside
the enclosure the performance was severely degraded due to
cavity resonances inside of the enclosure. The measured data is
shown below in Figure 2.
These are thin (.1 to 3 mm) polymeric materials filled with
magnetic particles. These materials have both high permeability
(magnetic loss properties) and high permittivity (dielectric loss
properties). This combination of properties makes these materials
very effective in eliminating high frequency EMI
Laird Technologies has two product types that are used for
commercial applications:
•Q-Zorb HP (high permeability) uses novel magnetic fillers to
achieve extremely high permeabilities at low frequencies. This
allows for relatively thin materials to provide EMI reduction at
frequencies below 2 GHz. This material comes in thicknesses
of .15 mm and .5 mm.
FOAM ABSORBERS
These absorbers are based upon open celled foam impregnated
with a carbon coating. The carbon coating makes the resultant
product lossy at microwave frequencies, indeed acting like a
free space resistor to incoming electromagnetic energy. These
foam products range from 3.2 mm to 6.4 mm for internal cavity
applications and can be several centimeters thick for outdoor
applications. Two main product types are offered by Laird
Technologies
•RFLS- Lossy sheets are uniformly loaded with the carbon
coating and used at 3.2 mm and 6.4 mm thick. They are
supplied as sheet materials and may have PSA applied and
fire retardant coatings.
•RFRET- is a reticulated foam based absorber. The materials are
thicker ranging from 3/8” to 2” in thickness. They can be used
for air filtration and EMI, or on the inside of cabinet doors for
broadband EMI attenuation.

•Q-Zorb HF (high frequency) is the optimum choice for cavity
resonance problems from 2-18 GHz and higher. The material
is available in thicknesses from .5 mm to 3.2 mm and is
supplied in sheets or as die cut components. Both materials
are UL-VO and ROHS compliant. They can be supplied with
pressure sensitive adhesive (PSA) for ease of installation.

DESIGN GUIDE FOR
COMMERCIAL MICROWAVE ABSORBERS
To improve the performance of the device, Laird Technologies
Q-Zorb microwave absorber was put on the inside cover of the
enclosure. This is a standard way in which absorbers are used.
Q-Zorb is supplied with a pressure sensitive adhesive to allow for
ease of installation. The cover is shown below in Figure 3.
MAGNETIC ABSORBER VS. LOSSY FOAM
In these enclosure applications the designer needs to understand
the tradeoffs between using the magnetic absorber vs the lossy
foam type absorber. The foam absorber is a much more cost
effective solution, provided it will meet the performance goals.
However there are a couple major reasons to use the magnetic
sheet absorbers (Q-Zorb)
•Foam absorbers can breakdown over time causing resistive
particles to drop onto to circuit traces
•Energy along the side walls of cavity are H field (magnetic)
dominated currents. The E field is at a minimum along the
walls and materials with only dielectric loss (resistive foams)
will not perform very well in these applications. The magnetic
absorbers have high H field loss and attenuate these currents.
Figures 5 and 6 below do show the use of a lossy foam absorber
inside of an amplifier cavity.
Figure 3. Enclosure with Q-Zorb PN 2238 Installed
The amplifier was then measured inside the enclosure with the
Q-Zorb in place. The performance of the amplifier now mirrored
the open condition by absorbing the internal reflections and
surface currents. Figure 4 shows this measurement.

TUNED FREQUENCY
VS SURFACE WAVE ABSORBERS
Laird Technologies offers two types of Q-Zorb materials: tuned
frequency and surface wave absorbers. Tuned frequency materials
are used in far field applications such as direct radar reflections
off of an object. Surface wave absorbers are used for high angle
of incidence applications and for cavity noise suppression. Many
design engineers that have a cavity noise problem at a certain
frequency want to use a tuned frequency absorber tuned to that
frequency. However that is not the best performance they can
achieve. Note that the tuned frequency materials offer good
performance at normal angles of incidence, but perform more
poorly at higher angles of incidence. Inside the cavity noise
generated is at a number of angles of incidence and also a
significant of surface wave energy. The surface wave materials
offer better performance in these applications. The curves below
compare a tuned frequency absorber at normal incidence and
at all angles of incidence. Note the improved bandwidth of the
surface wave loading especially at higher angles of incidence.
The Q-Zorb samples in the Laird Technologies Absorber sample
kit are the surface wave absorber type. They are the best solution
for solving cavity noise problems.

EMI MODELING
SAMPLE KIT
Laird Technologies is a member of the EMC Consortium at
Missouri Science and Technology School, Rolla Missouri. As
part of this consortium Laird Technologies is modeling the use
of absorbers for a variety of applications. The cavity application
discussed above is one of the key areas of investigation. Other
areas include directly placing absorbers on noisy chips, coating
cables to reduce conducted EMI, and use on antennas. Laird
Technologies is working on modeling these applications using
3D modeling software including HFSS, Microwave Studio, and
EZ-FTDT. The Q-Zorb can be modeled as a Debye Oscillator and
directly input into the codes. Laird Technologies can supply these
models to customers for their own computer modeling. A few
examples of this work are shown in the figures below.
To assist the microwave design engineer in the use of Laird
Technologies absorbers, a sample kit containing the different types
of microwave absorbers is offered. The kit contains all three types
of materials including Q-Zorb HF, Q-Zorb HP, and RF Foam.
A description of the sample kit is listed below.
Figure 7. Microwave CST Model of Cable with Q-Zorb Coating
www.lairdtech.com
The samples are 6”x 4” in size and can be easily cut into specific
shaped pads. There are various thicknesses to evaluate. Generally
speaking the thicker the sample the better it will work at low
frequency. However if you are constrained by thickness, evaluate
the one that will meet the thickness requirements and then test
the electrical properties of the sample. To make even thicker test
samples the samples can be bonded together. This will allow the
designer to evaluate thickness vs performance.

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
• Place on top of noisy chip to reduce emissions
•Wrapped around cables to reduce conducted
emissions
•Used inside of board level shields to improve
shielding performance
Two standard part numbers of Q-Zorb 3000 are
available in the absorber sample kit. This allows the
engineer to see if this product will help solve any
specific EMI problem.

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 Technologies 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

ABSORBER BOARD-LEVEL SHIELDING (ABLS)
FIGURE 1.
Increasing use of printed circuit boards in complex electronics
requires unique shielding solutions. Laird Technologies has
developed a near field measurement to accurately determine the
effectiveness of board-level shielding. Several Laird Technologies
board-level shields have been characterized using this technique.
Laird Technologies 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 FLOEMC 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 Technologies 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 Technologies has a network analyzer to make amplitude
and phase measurements from 130 MHz to 20 GHz. Laird
Technologies 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 Technologies to build a database
that customers can use to design new absorbers and analyze
their performance in different situations.
