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 125C 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.
