BERYLLIUM COPPER SOLUTIONS AND BEYOND.
Large-volume requirements are readily met
by our high-speed Bruderer punch presses.
Large bed presses enable
Laird Technologies to process
a wide variety of material
types and thicknesses to broaden our
metals capability and offer customized
solutions from shielding, grounding or
non-EMI applications.
Heat-treating, critical to imparting the
specific mechanical qualities to the spring
materials, is computer-controlled. All heat
treated batches are also quality tested for
hardness and specifications.
Photo-chemical machining produces
extremely intricate and complex parts to
precise specifications and provides a cost-
effective alternative to tooling.
Multi-slide machines offer economical
production options.
From design to totally automated assembly,
Laird Technologies offers complete control
of your assembled product.
Our precision plating departments support
and strictly comply with environmental,
health and safety standards while offering
a wide variety of plating finishes.
This environment-friendly, aqueous
degreasing unit for removing
stamping oils cleans with a mild
alkaline solution—eliminating the
need for chlorinated solvents.
Beryllium copper has remarkable stability, superior tensile strength,
impressive thermal and electrical conductivity, and high shielding
attenuation values. Which is why Laird Technologies®offers over 250
different configurations of beryllium copper shielding. Beyond beryllium
copper, we also offer shielding and custom-engineered stampings in
stainless steel, brass, phosphor bronze and other special alloys.

As the world’s leading fabricator of fingerstock, Laird Technologies has developed
highly sophisticated, and often proprietary, shielding and grounding technology.
Our innovations are necessary to achieve outstanding combinations of
performance parameters. From a vast selection of product configurations,
platings and mounting techniques, to a full range of low compression
force requirements and high transfer impedance characteristics, there is a
Laird Technologies gasket or grounding product just right for the job.
Depending upon the manufacturing process, some parts will be
supplied with holes for cleaning and plating purposes. These holes
will not affect the overall performance of the product.
Consider these important factors in
the selection of appropriate shielding
products for your design:
Operating Frequency
Materials Compatibility
Corrosive Considerations
Commercial or Military
Worldwide Compliance
Operating Environment
Load/Forces
Cost
Attenuation Performance
Fastening/Mounting Methods
Storage Environment
Nuclear, Biological, Chemical (NBC)
Cycle Life
Shielding/Grounding/Other
Electrical Requirements
Materials Thickness/Alloy
Space/Weight Considerations
Product Safety
Recyclability

MOUNTING METHODS
1.10 www.lairdtech.com
Laird Technologies shielding devices may be mounted quickly and easily
using any of several different methods. Each installation method is described
in the text that follows. However, if you should run into a unique situation
not resolved by any of these methods, give us a call. More than likely we
can provide the exact answer you need.
RIVET MOUNT
Riveting produces a tight, long-lasting installation. Either plastic or metal rivets
may be used.
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.
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).
Simply follow these four easy steps:
1.Remove all grease and oily residue with solvent. Smooth the mounting
surface with emery cloth.
2.Peel off protective paper backing.
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.
NOTE: On items where fingers cover the solid portion of the gasket, pressure
may be applied by inserting a mandrel in the strip and pressing down. For
contact strips with Magnefil®insert, simply press down on the fingers.
4.Allow 24 hours minimum curing time.
Standard parts are supplied with nonconductive tape. For rough surface
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.
CLIP-ON MOUNTING
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.
TAPE TRACK MOUNTING
Stainless Steel mounting track with PSA (pressure sensitive adhesive) is
available on the Symmetrical Slotted Series and Slot Mount Series.
WELDING
Welded mounting requires simple, traditional welding techniques.
SOLDERING
Solder mounting requires normal low temperature soldering techniques,
including cleaning and fluxing of parts with common copper flux materials.
SLOT MOUNT
^Shielding gaskets may be mounted for either wiping or
compression closing applications. Proper positioning of the
shielding gasket must take into consideration the closing
design and the configuration of the mounting surface.

Laird Technologies offers a unique product designed to shield the front panels
of IEEE standard 1101.10 card cages, commonly referred to as Dot-10, called
the Compact PCI gasket.
This front panel shielding has been designed to shield between the front
panels on sub racks and plug-in units. This is a beryllium copper solid top
symmetrical slotted fingerstock strip pre-plated in sulfamate nickel. It is
designed to mount on the “T”shape on a front panel extrusion (see below).
Specially designed for wiping applications, this configuration allows total
symmetrical compression action with bi-directional engagement.
Standard size shown is based on the 9.5" (241.300) length per the Dot-10 standard.
Other lengths and plating finishes are available for your specific application.

All dimensions shown are in inches (millimeters) unless otherwise specified.
WITH STICKY FINGERS
Series 97-951/954/957 are low compression, adhesive-
mounted 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 1-11. For load/deflection data, see page 2-33.
WITH BI-DIRECTIONAL RIVET MOUNT
Series 97-952/955/958 are as described above, but
with the addition of an integral pierced brass track
to provide plastic push rivet mounting in a 0.125 in.
(3.175 mm) diameter hole.
Designed especially for slide applications, this configuration allows total
symmetrical compression action with bi-directional engagement. It is
recommended for high temperature and/or extremely high side load situations,
such as PC board connections and electronic drawers. All are available in
your choice of finishes, see page 1-11. For load/deflection data, see page
2-33. Both are available in UltraSoft®low compression force 98-Series.

These versatile gaskets are made from high-performance
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.
Strips 97-500 and 97-538 are furnished in standard lengths of 24.000 in.
(609.600 mm) and in continuous 25.0 ft. (7.6 m) coils. Series 97-520 and
97-540 are supplied in standard 16.000 in. (406.400 mm) lengths and in
25.0 ft. (7.6 m) coils. Strips 97-537, 97-535 and 97-545 are supplied in
12.000 in. (304.800 mm) lengths. All are available in your choice of finishes,
see page 1-11. For load/deflection data, see page 2-33.
Please note that designated strips are available with Magnefil®, a rubber
strip filled with magnetic absorbing particles and inserted within the curve
of the fingers. Magnefil provides increased magnetic field shielding.
These 97-Series products are also available in UltraSoft®low compression
force 98-Series.

®®
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
1-11.
For load/deflection data, see pages 2-33.
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 omni-directional grip with excellent conductivity.
GRIP-TITE®WITH “T”LANCE
Ideal for use with softer materials, such as aluminum or plated plastic. “T”
lances bite into the mounting surface and preserve electrical conductivity.
MINI CLIP-ON
Laird Technologies’ Mini Clip-On (97-645/646) Gaskets are designed for use
on today’s thinner, lighter materials.
•Lowest compression force available in clip-on configuration
•Virtually no compression set – 100% recovery of original height
at up to 60% compression
•“D”lance for extra holding power
•Optimum conductivity and mechanical properties of beryllium copper
•High cycle life – 50,000 cycles without fracture, wear, or compression set

LARGE ENCLOSURE SERIES
These standard beryllium copper contact gaskets offer ideal RFI/EMI shielding
of doors and movable components in electronic shielded rooms, trailers, computers
and communication equipment.
They have been scientifically designed for wiping closures, but are also usable
in compression applications. Moreover, these contact strips feature extremely
good endurance life, as well as a high deflection range. In tests, attenuation
up to 112 dB has been measured for a 100 MHz plane wave. Fastening of
the strip is usually accomplished using screws or rivets. Soldering is optional.
Both are available in continuous lengths to a maximum of 25.0 ft. (7.6 m) and
in all standard finishes, see page 1-11. For load/deflection data, see page 2-33.
These 97-Series products are also available in UltraSoft®low compression
force 98-Series.

This version of Sticky Fingers®beryllium copper shielding gaskets features a
special U-shaped end that permits the finger of the strip to slide when enclosure
doors are closed. It also retains the strip’s fingers when enclosure doors are
open, thus preventing accidental damage to the fingers. Shielding effectiveness
is >115 dB for a 100 MHz plane wave.
Four models provide you a choice of widths to suit your application. They are
available in standard 16.000 in. (406.400 mm) lengths, except 97-515 which

Laird Technologies introduces the Card Guide Clip-On, which offers excellent
grounding contact from the PC board to a card guide on a rack. The unique
snap-in feature of the contact finger prevents any potential snagging. This
allows for bi-directional sliding contact. The
Card Guide Clip-On
gasket installs
to the edge of the board and makes contact with ground trace on the card.
The card then slides into the card guide on the rack. Low compression forces
allow for easy installation of the card.
•Easily installs onto PC board
•Provides for bi-directional wiping that eliminates snagging
•Ideal, inexpensive solution for grounding applications
•High-performance beryllium copper can be plated with a wide
variety of finishes for galvanic compatibility, see page 1-11
•Designed for board thicknesses of 0.085 in. to 0.100 in.
(2.159 mm to 2.540 mm)
•Design capabilities available to handle other board thicknesses and custom
applications

CUSTOM STAMPING—DRAWN CAN BOARD LEVEL SHIELDS
2.27 www.lairdtech.com
All dimensions shown are in inches (millimeters) unless otherwise specified.
Laird Technologies™has added Drawn Cans to its extensive list of board
level shielding solutions. As microprocessor speeds continue to increase,
so does the potential for EMI leakage through the smallest apertures in
board level shields (BLS). Laird Technologies’ Drawn Cans 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 BLS solutions. Drawn cans utilize small ground trace sizes,
thereby preserving packaging space on the PC board.
•Solid corner designs when additional circuit isolation (attenuation)
is required at higher frequencies
•Available in heights up to 0.250" (6.350 mm) with length and width
dimensions from 0.300" (7.620 mm) to 2.000" (50.800 mm)
•Unlimited configurations of ventilation holes can be incorporated
into the design
•Tape and reel packaging provides an economical and automated
SMT attachment method
•Available in cold-rolled steel (CRS), brass, stainless steel, and
nickel silver
•Multi-compartmental shielding of components can be achieved
with formed partitions
•Mold-In-Place and Form-In-Place Elastomers can be combined
with drawn cans to achieve shielding of multiple components
with a single part
•Available with an EZ Peel scored lid feature; allows for easy
top section removal for component repair and re-sealing
Laird Technologies can custom design a shield specifically to meet your
requirements or we can utilize your approved design.

CONTACT RINGS

www.lairdtech.com
All dimensions shown are in inches (millimeters) unless otherwise specified.
The large variety of sizes and shapes of contact rings offers engineers a wide
choice in meeting design requirements for microwave cavities, tuning, shielding
and grounding applications. Rings are made from strip stock formed into an
unclosed circle which, when assembled, becomes a complete ring. These rings
are furnished in any diameter, greater than the minimum shown in the chart
below, and must contain an integral number of fingers.
Most configurations are available with Contips®, described in the preceding
section.
Available in standard finishes, see page 1-11.

SAMPLE LOAD CHART FOR GROUNDING STRIPS
FINGERSTOCK LOAD DATA
Efficient enclosure design requires an understanding of the compression force
necessary to close gasketed joints. Toward this end, Laird Technologies has
developed the following charts indicating compression forces required to achieve
optimum gasket performance from each of our fingerstock gaskets. Loads are
expressed in “pounds per linear foot”(or as “kilograms per linear meter”).
Load Tests: Bare BeCu mated against mild steel having a ground surface,
roughness approx. 16 m in. (0.4 mm).
DEFINITIONS:
Largest opening
is the height at which contact force is the minimum required
for reliable shielding performance.
Design height is the height which allows maximum deviation in both directions.
This is recommended in most cases.
Smallest opening is the smallest height which precludes damage to the gasket.
SHIELDING EFFECTIVENESS
Shielding effectiveness of fingerstock gaskets does not vary significantly with
compression. The graph below shows finger gaskets tested at five different
heights. Variation is only about 10 dB, which is typical of most fingerstock
gaskets. Compression of a finger gasket beyond “design height”does not
benefit performance, but can complicate enclosure design.
GROUNDING STRIPS
Some fingerstock products are used as grounding strips, or in other applications
carrying RF current. Because these products are basically flat, their loads are
expressed as a function of “deflection”rather than height.

** Projected H-Field data
STRIP METAL GASKETS
The graphs and tables of radiated and transfer impedance measurements in
this section compare beryllium copper (-02) with either tin plating (-08) or bright
tin plating (-17), in various gasket configurations.
Obtaining the same level of shielding effectiveness shown in the following tested
gaskets to MIL-DTL-83528, Para. 4.6.12 or SAE ARP 1705 may not be accomplished
without an equivalent test flange/fixture configuration. Many mechanical factors
(size, tolerances, cover plate fastening/holding, flange stiffness, etc.) influence
performance by enhancing or lowering shielding effectiveness.
The data presented provides a valuable electrical design tool for gasket
material comparison/selection. Radiated shielding effectiveness values can
be approximately 38 dB higher than transfer impedance shielding effectiveness
values. This is because the measurement is influenced by the characteristic
impedance of the transmission line fixture with respect to the localized ground
reference. The specified MIL-DTL-83528 radiated fixture aperature is 24.000
in. x 24.000 in. (609.600 mm x 609.600 mm), This aperature size results in
attenuation, along with reflections and resonances, which creates a test
anomaly at 200 MHz, thus limiting the measurable shielding effectiveness.
The specimen configuration as specified in MIL-DTL-83528 is a 1.000 in.
(25.400 mm) wide flat strip; in contrast, the data presented in this section
is based on a wide range of specimen configurations for practical shielding
design applications.
Note: For all gaskets, shielding effectiveness measurements were taken at
recommended compression.

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.
Simple assembly of the shield is accomplished by snapping the two shield
halves onto an uninstalled guide rail assembly. The rail is then mounted onto
the printed circuit board in the normal fashion.
Spring finger design on both halves of the GBIC shield provide grounding for
both sides of a transceiver module. In addition, the bottom half fingers can
provide a low impedance connection to the circuit board ground plane.

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, we provide properly designed contacts that ground, carry current
and signals, and interconnect boards and devices. We do this by using 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
your product's operational performance. We also incorporate features 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. We have exclusive processes such as our
innovative Mako process, which selectively plates contacts with precious metals
only in the necessary areas. This eliminates bare edges and reduces costs.
Our 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.

CORROSION OF EMI GASKETS
5.1
www.lairdtech.com
GALVANIC CORROSION OF METALS
The galvanic series is a common means of ranking the relative activity of
metallic couples. The galvanic series does not provide a measure of the
corrosion current which will flow in a dissimilar metal couple, but it does
indicate which couples are likely to incur significant corrosion damage. In
galvanic couples consisting of two very incompatible metals, it is possible to
reduce the corrosion rate through good design practice. In this situation, it is
best to maximize the ratio of anode to cathode surface areas. For a particular
current density, the corrosion rate on the more anodic metal will be lower
the larger this ratio, because the corrosion reaction is spread over a larger
surface area. In addition, if corrosion products build up on the cathode, they
will build at a faster rate the smaller the surface area of the cathode relative
to the anode. In this situation, the deposits could create a barrier that slows
down corrosion.
The above technique is used in reverse to enhance the performance of electrical
contacts. It is desirable that electrical contacts remain clean to provide a low
resistance connection. When corrosion occurs, metal is removed from the
more anodic metal. This process cleans the more anodic metal. By making
the electrical contact out of one metal and surrounding it by a larger surface
area of a more cathodic metal, the contact will be cleaned by the corrosion
reaction. The contact may corrode away eventually, but it will function more
reliably during its shortened life.
The probability that two dissimilar metals will corrode when coupled together
can be predicted from their difference in the electrochemical potentials. This
information is tabulated in the Metals Galvanic Compatibility Chart on page
5-2. The common metals and their anodic index are listed along the left side
of the chart. The metals are grouped in 0.05 volt increments, with some of
the groups containing no common metals. Group Number One (left hand
column) contains the most cathodic metals and has an anodic index of zero.
The anodic index increases as metals become more anodic. The arrow (on the
far right hand side of the chart) points in the direction of increasingly anodic
metals. On the right side of the chart, typical finishes available on metallic parts
manufactured by Laird Technologies are listed along the top. The colored bars
indicate the galvanic compatibility of these common finishes to the metals listed
on the left. The color code is based on both the electrochemical differences
between the metals and the finishes and the corrosiveness of the environment.
The chart shows that the force that drives the corrosion reactions is directly
related to the electrochemical difference between any two metals. By reducing
this difference, the corrosion rate is decreased.
BASIC CORROSION PREVENTION
Whenever possible, avoid the use of dissimilar metals. The following five steps
may be taken to prevent, or at least minimize corrosion potential in the
event
that it is necessary to use dissimilar metals in intimate contact with one
another:
1. Limit contact between metals with widely different electrochemical
potentials. The Metals Galvanic Compatibility Chart, on page 5-2, indicates
which metal pairs have large differences in electrochemical potential.
2. Insert a third metal between the two dissimilar metals which reduces the
potential difference of the galvanic couple. For example, nickel or tin plated
copper is suitable for use with aluminum and silver combinations.
3. Design the flange interface so that the surface area of the anodic metal
is significantly larger than the cathodic metal. The electromotive force
(EMF) difference remains the same. However, the current density is
decreased, so the corrosive attack on the cathodic metal is reduced.
4. Eliminate moisture, salts and other electrolytes from entering the
joint
interface by improved flange design or, if not possible, use an
environmental
seal outboard of the conductive element in a dual
EMI shield/environmental seal.

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 the
light 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 stored
in 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.
