Proposition:

SOFT-SHIELD

3700 allows the use of fabric over foam

EMI/Grounding gasketing technology to be used in elevated

temperature applications where continuous operating

temperatures of 125

C or less are required.

These cost effective, high performance gaskets with a UL

94-V0 ﬂammability rating, provide EMI shielding solutions for

the automotive, military and information technology market

applications in higher temperature areas previously not

possible with urethane foam based products. SS3700 can be

rapid prototyped in many conﬁgurations and allows ﬂexibility

integrating it into new or current designs. The part will not

require expensive tooling, virtually eliminating supply start

up costs. The material is highly reliable ensuring years of

positive performance. The nickel plated copper polyester rip

stop fabric is resistant to oxidation thus delivering years of

shielding and electrical grounding. Further, the characteristic

low compression set of these foam based gaskets provides

more reliable long term shielding, especially in applications

where gasketed enclosure ﬂanges are frequently opened and

closed. Unlike alternative solutions such as metallic ﬁngers,

the material will not break or crack during handling thus

improving production ﬂoor yields and avoiding the potential for

a broken fragment falling onto a PCB. The material delivers

shielding/grounding at a low deﬂection force over a large

deﬂection range allowing for a relaxation of mechanical

tolerances. SS3700 can accomodate up to 50% of it’s cross

sectional height enabling it to accommodate a wide range of

tolerance stack up and still shield. This reduces dimensional

constraints and cost on all other components.

Since they are offered with a conductive Pressure Sensitive

Adhesive (PSA), installation of SOFT-SHIELD 3700 gaskets

is made simple and can be delivered in several ways to the

factory ﬂoor.
