GORE SMT EMI Gaskets and Grounding Pads Excellent electrical performance with SMT convenience GORE SMT EMI Gaskets and Grounding Pads combine unsurpassed conductivity with the convenience of SMT- compatible format. These conformable components are engineered to maintain consistent contact and low DC resistance. Unlike the traditional designs of pogo pins and universal clips that can easily break, the robust design of GORE SMT EMI Gaskets and Grounding Pads increase durability with large contact surfaces rather than single-point contacts. The unique construction of GORE SMT EMI Gaskets and Grounding Pads ensures that the device maintains signal integrity and reliable electrical performance in harsh environments. Because of their compatibility with SMT equipment for printed circuit board production, GORE SMT EMI Gaskets and Grounding Pads reduces total costs. Using these off-the-shelf components eliminates the need for custom designs that can Bene ts of GORE SMT EMI Gaskets increase engineering costs. Also, no secondary processing is and Grounding Pads required, which reduces equipment and labor costs during production. Using precise SMT equipment to incorporate Excellent shielding effectiveness and low DC resistance with conformable construction GORE SMT EMI Gaskets and Grounding Pads improves the consistency and repeatability of PCB assembly, thus Reliable electrical performance achieved through decreasing waste. consistent contact over time Reduced total costs versus custom options due to GORE SMT EMI Gaskets and Grounding Pads offer a full standard sizes and compatibility with SMT technology spectrum of working ranges, making them ideal for use as Increased design exibility with easily integrated grounding pads, EMI gaskets, and antenna contacts. The highly standard parts compressible SMT Supersoft Series delivers consistent electrical performance with minimal force required for initial conductivity. Consistent and repeatable assembly with parts that need no secondary processing The SMT GS5200 Series offers the highest conductivity under compression in Gores EMI shielding product line. In addition to Enhanced durability due to conformable material that maintains contact over time without compromising the these high-performance characteristics, GORE SMT EMI Gaskets integrity of the mating surface and Grounding Pads have been tested against a variety of Faster production times because of standard solder environmental standards (Table 1). process that requires no cure time Typical Applications Portable electronic devices such as smartphones and tablets GPS and handheld scanners/readers Telematics Gaming devices Personal computers and laptops Telecommunication infrastructure GORE SMT EMI Gaskets and Grounding Pads are covered by patent No. US 6,255,581 B1 and US 6,210,789 B1.
