EMI ESSENTIALSEMI ESSENTIALS
Series UltraSoft
®
ngers 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 congurations, UltraSoft ngers offer
designers greater exibility and versatility than ever before—permitting more extensive use of lighter, thinner construction materials
to help cut costs and/or enhance system performance.
The unique advantages of UltraSoft (98-Series) ngers include:
• The lowest compression forces in the industry
• Shielding effectiveness comparable to similarly congured standard 97-Series parts
• Wide selection of sizes and congurations
• 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 specic information. All UltraSoft products are also available in your choice of nishes.

Recyclable Clean Copper products meld
strong stability and tensile strength
with high levels of thermal and
electrical conductivity making it suitable
for utilization in both grounding and
shielding applications at a cost that is
comparable with traditional metal EMI
shields. Shielding effectiveness is similar
to other copper alloys with values over
100 dB shielding effectiveness readily
achieved.
Recyclable Clean Copper is fully
compliant to EU Directive 2002/95/EC
and alleviates the environmental, safety
and segregation concerns associated
with the traditional use and recycling
of beryllium-based copper alloys.
This alternative material exhibits
excellent corrosion resistance,
platability, solderability and stress
relaxation properties.
The product is targeted at high
volume designs. Custom stampings
are available upon customer request.
As with all of Laird metal
ngerstock gaskets, Recyclable Clean
Copper is completely ameproof.
For mounting methods and other spe-
cic product information, please
see Laird catalog
“Fingerstock, Gaskets and Metal
Grounding Products”.
