Conductive Tapes

More flexibility, higher conductivity, and easier installation Schlegel Electronics Materials' (SEM) expanded line of Conductive Tapes meets the customer needs for flexibility, higher conductivity, and easier installation. They are vailable with conductive and non-conductive adhesives and in a wide range of widths. Typical applications include cable Shielding terminations and joining metal panels together at the seams of an enclosure. Foil tapes are a cost-effective shielding solution for a wide range of uses. They can be particularly useful during the development and test phases of projects to be used as "fixes" for EMI problems. SEM's masked conductive tapes are also available and can be used as a gasket substrate on painted or stove enameled enclosures. Also available are special purpose adhesive tapes to include: Pressure sensitive adhesive die-cuts High-tack adhesive die-cuts Low residueadhesive die-cuts Silicone adhesive die-cuts Insulation adhesive die-cuts Heat resistive adhesive die-cuts SEM's Conductive Tapes feature superior shear strength, 7.6 kPa (72+ hours @ 1.1 psi) in accordance to (PSTC #7) ASTM D 3654, and peel strength, 10.2 N2.5 cm. (36.07 ozinch width) in accordance to PSTC #1) ASTM D 3330, when compared to other EMI shielding tapes. This is made possible by a unique, cross-linking acrylic based, conductive Pressure Sensitive Adhesive (PSA) that also allows the tapes to be designed into higher temperature applications. The PSA is fire-rated to UL 510, and excessive pressure is not required for application to the end unit. There is now an easy-to-apply tape to fit most every EMI shielding design need.

I/O Shielding Gasket

Schlegel Electronic materials (SEM) IO gaskets provide effective shielding for everything from computers to consumer electronic devices to large arrays in telecommunications cabinets. The diversity and durability of SEM's IO gaskets come from the combined strength of the gaskets’ highly conductive fabric and soft, highly resilient urethane foam core. Under compression, the soft foam helps the gasket hug the connector perimeter and allows the fabric multiple contact points. The result: exceptional conductivity, the ability to provide shielding beyond 10 GHz and the capacity to compensate for tolerance stack-up, significant advantages over stamped metal, fingerstock, and elastomeric EMI shielding products. SEM IO gaskets are easy to install and robust when exposed to repeated compression and temperature cycling. SEM has numerous standard gasket profile designs, which help OEMs eliminate the high cost of stamped metal tooling and provide for easy ordering and fast delivery.

  • Shielding Effectiveness 0.1-40 GHz
  • Operation Temperature -40°F +156°F (-40°C +70°C)
  • Flammability UL94 V0

Information Technology Equipment and other electronic devices must comply with various international radiated emissions and susceptibility requirements. Under specific conditions, FCC part 15 (US) requires such equipment to pass stringent regulations up to 40 GHz. Most unintentionally-radiated emissions are from field leakage at various chassis external interfaces, or from unbalanced differential signals; containment of both require shielding materials to provide a low impedance path despite the broadband andor high frequency operation of such devices. Simultaneously, these electronic devices are sensitive to various susceptibility requirements, including electrostatic discharge (ESD, e.g., IEC 61000-4-2), and, in some cases, must resist to applied voltages as high as 15 kV. In this instance, the same shielding materials must also feature a very low impedanceresistance at very low frequencies to ensure a harmless discharge path exists to allow the charge to flow from the IO connectors to the exterior of the chassis, and then safely away from the devices. Schlegel Electronic Materials (SEM) introduces ORS-II, a new series of gaskets specially designed for broadband applications. By combining its famous nickel copper plated conductive foam and its high-end nickel copper C12 flexible fabric cladding, ORS-II offers minimal surface resistance to achieve superior grounding and shielding results at low frequencies. By offering excellent Z-conductivity to close the cavities in the chassis openings, ORS-II also ensures substantial shielding performance at high frequencies. ORS-II is available in a variety of thicknesses, which are die-cut to customer specifications, for a durable highly conductive product in all X-Y-Z axes. In addition, shielding efficiency is achieved with less sensitivity to compression variances than other traditional shielding products. ORS-II is available with a UL94-V0 flammability rating and complies with RoHS 2.0 European Directive and SVHC Policy (REACH).

Schlegel Electronics Materials (SEM) line of silicone gaskets provides shielding capability in diverse markets and applications, including the military, aerospace, medical, fluid seal, environmental and microwave applications. Our silicone elastomers are specifically designed for gasketing applications that require high levels of attenuation up to 120 db. SEM is renowned for its high quality EMI shielding gaskets. We provide a full family of products to meet a wide spectrum of shielding needs. Our silicone gaskets meet customer needs in a variety of markets, with very competitive pricing. Engineers can now fulfill all their shielding needs from one manufacturer, rather than having to go through multiple distributors or resellers. Silicone, the base material for elastomers, has environmental sealing properties. Shielding is achieved by incorporating various media in the silicone, depending on the product. Wire is used to provide conductivity in the oriented silicone line and a non-corrosive particle is added to the extruded parts. Because conductive elastomers can be extruded, many different profiles and lengths can be made to suit any application
