GORE SMT EMI Gaskets and Grounding Pads Supersoft Series 6101 Ensure Consistent Electrical Performance with Highly Compressible Construction in SMT Compatible Format The Supersoft Series of GORE SMT EMI Gaskets and Grounding Pads are standard components that enable designers to create EMI shields in non-linear 2-D or 3-D shapes, reduce device thickness where EMI cans are used, and create grounding points as needed in a very small footprint on the circuit board. These components are highly conductive on contact, easily compressed with minimal force, and resilient after compression. These features ensure consistent electrical performance and makes Gores Supersoft Series an excellent choice for EMI shielding or grounding for systems such as LCDs, flexible circuits, antennas, and cameras and devices such as smart phones, tablets, and laptops. The highly compressible construction, requiring low closure forces, makes it suitable for devices with plastic housings and also provides consistent contact in housings that have surface variations such as aluminum as-cast enclosures. Benefits of GORE SMT EMI Gaskets and Grounding Pads Targeted Applications Excellent shielding effectiveness, with low DC Mobile phones resistance in small standard component and minimal force required Tablets Offers more design flexibility with standard component, Laptops and speeds time to market due to eliminating the need Camera modules for custom parts Flex circuits Supports fast, high volume production due to SMT compatibility Reduces circuit board area due to small component size Reliable electrical and mechanical performance due to conformable material that maintains consistent contact without compromising the integrity of the mating surface Gores Supersoft Series 6101 packed in reel tape NEWGORE SMT EMI Gaskets and Grounding Pads Force Displacement Resistance The Supersoft Series provides conductivity on contact however, the amount of force and DC resistance changes as the part is compressed as shown in Table 1 and Figure 1.

Recoverability measures the gaskets ability to maintain 0.35 some level of gap-filling following a release of a compression 0.30 60 load. Using ASTM D395 B, Standard Test Methods for Rubber Property, Test Method B: Compression Set under Constant 0.25 Deflection in Air, the Supersoft Series of GORE SMT EMI 0.20 40 Gaskets and Grounding Pads have demonstrated high levels of 0.15 recoverability immediately following release of the compressive 0.10 20 load (Figure 2).
