fingers have been designed for communications, computers and
electronic systems designers concerned with EMI compliance and lightweight
enclosure designs.Available in the same full range of standard configurations,
UltraSoft fingers offer designers greater flexibility and versatility than ever
beforepermitting more extensive use of lighter, thinner construction materials
to help cut costs and/or enhance system performance.
The unique advantages of UltraSoft (98-Series) fingers include:
The lowest compression forces in the industry
Increased life cycle
Shielding effectiveness comparable to similarly configured standard
97-Series parts
Wide selection of sizes and configurations
Low compression force version available for virtually every standard
shielding product
UltraSoft (98-Series) products are available in the same lengths as the standard
(97-Series) products. Please refer to the appropriate standard product pages
for specific information. All UltraSoft products are also available in your
choice of finishes, see page 17.

Contact strips are used for grounding and shielding in high-frequency equipment
and for forming large diameter contact rings.
A wide variety of beryllium copper contact strips provides engineers and
designers with flexibility in solving grounding and shielding problems. Various
lengths, widths, thicknesses, contours and hole locations are possible for
many of the standard catalog items shown here.
For standard finishes, see page 1-11. For load/deflection data, see page 2-33.

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.

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.

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.

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

All dimensions shown are in inches (millimeters) unless otherwise specified.
Laird offers an addition to our connector gasket line, part number 97-787,
which is designed to fit all IEEE 1394 horizontal connectors. Made from
copper beryllium, these gaskets provide superior grounding and reduce
emissions from the connector by providing a low-impedance grounding path
from the connector shell to the faceplate.
The gasket is mounted over the top of a horizontal IEEE 1394 connector and
soldered to the board. Contact with both the faceplate and the connector
shell is accomplished once the board is assembled into its housing. These
gaskets can be provided in trays to facilitate pick-and-place assembly onto
the board and wave soldering automation.
Accommodates a wide range of connector protrusion positions
Fits all IEEE 1394 horizontal connectors
Gasket can be placed onto the printed circuit board via pick-and-place
Packaging to accommodate high-speed assembly is optional
Simple thru-pin mounting method
Grounds the connector to the faceplate
Available in a variety of plating finishes

Laird offers the USB (Universal Serial Bus) Type B connector gasket.
The unique design easily snaps onto the connector prior to placement on the
printed circuit board and fits all Series B USB right angle connector brands.
Made from high performance beryllium copper, these gaskets provide superio
r
grounding characteristics and enhances the shielding of the connector due to
the short electrical path to the ground plane provided when the gasket makes
contact with the connector.
Gasket easily snaps onto the connector for a secure fit
Connector/gasket assembly can be placed onto the board via pick-and-place
High clip force attaches clip to connector body for good electrical contact
and secure transport prior to soldering
Once the shielded connector assembly is soldered to the PCB, the shield is
captivated between board and connector and provides reliable contact
between the connector and faceplate
Simple compact design fits within 0.625 in. X 0.625 in. (15.875 mm X
15.875 mm) windows
Available in a variety of plated finishes
