Shielding products

Shielded windows, beryllium-copper finger strips, and coated polyester film are supplied for a variety of applications that require RFI screening. Shielded windows, which are cast by setting a conductive mesh within a polyester resin, resist shock, vibration, chemicals, and solvents and will operate between ­60° and 100°C. They can be subjected to 130°C for one hour. Beryllium-copper finger strips combine a mechanical springlike action similar to steel with the electrical conductivity of copper. The strips can be soft-soldered or resistance-welded without damage to the working surface; fixtures can be edge-mounted or applied with a fitted high-tack adhesive tape that is supplied with all front-mounting parts. The company also offers optical-grade polyester film that features excellent light transmission and that can be used as a shielded window when combined with a conductive layer.The material will not cause moiré patterns. Warth International Ltd., Grinstead, E Sussex, UK.

Shielded filter windows

Shielded filter windows enhance contrast while protecting electronic displays from radio-frequency emissions generated by enclosed electronic equipment. The windows also guard against penetration of EMI from external sources. The conductive microscopic wire mesh is encapsulated within the one-piece filters to avoid delamination and optical imperfections. The company offers complete fabrication services, from prototyping to full production. Full edge termination manufacturing and silk-screening services can be supplied. Instrument Plastics Ltd., Maidenhead, Berks, UK.

Shielding covers

Lightweight, reusable shielding covers fabricated from a thermoset plastic protect electronic enclosures from EMI emissions. A conduc-tive elastomer is moulded onto the entire cover surface, including sidewalls, to shield from EMI emissions; custom-moulded internal walls add circuit-to-circuit cross-talk protection. The covers eliminate the need for conductive paints, platings, and separate EMI gaskets. Metal inserts for mounting hardware are included to facilitate installation. Parker Hannifin plc, Poole, Dorset, UK.
Shielding strips

Beryllium-copper shielding strips are available in client-specified lengths or on continuous reels. The products can be supplied with nickel- or tin-plated standard finishes as well as alternative finishes, and come with standard riveting holes. A variety of fixing methods are offered, including self-adhesive, clip-on, and track-mount configurations. The company's complete range of products that are designed to help manufacturers of electronic equipment achieve compliance with the Electromagnetic Compatibility Directive are described in a recently published brochure. C. Brandauer & Company, Ltd., Birmingham, UK.

Architectural shielding

A copper-plated nonwoven material can be applied to walls, ceilings, and floors to protect against EMI. The air-permeable covering, which is corrosion-protected and weighs only 55 g/m2, guarantees a shielding effectiveness between 80 MHz and 1 GHz at 60 db minimum when combined with appropriate shielded components. Specially designed shielding systems for doors, windows, and ceiling and wall fastenings are available. The company also offers a complete turnkey shielding system that includes a preliminary study of the site and installation of the fabric and components. Shielding effectiveness certification is carried out in accordance with MIL STD 285. N.V. Schlegel, Gistel, Belgium.

EMI shielding tape

A lightweight and conformable metallized-fabric tape features high levels of conductivity and shielding. The tape combines Flectron, a copper-plated polyester fabric developed by Monsanto, with a conductive acrylic adhesive. Because of its flexibility, the tape is well suited as a shielding wrap for constantly flexing cables. Weighing 75% less than standard 1-oz copper-foil tape, 3M 1190 is also recommended for electronic applications where weight is a concern. 3M, Bracknell, Berks, UK.

Transparent coatings

Transparent conductive coatings can help protect flat or shaped transparent parts from EMI and electrostatic discharge. Three types of coatings have been developed for application to substrates with different electrical properties. ELAMET trans, which is transparent in the visible light range and reflective in the IR spectrum, is suitable for deposit on display interiors. SICRLAN DHC, a nonreflective hard coating, is designed for outer applications and protects substrates from scratches and UV attack. The company also supplies ELAMET, a metallization process that enhances EMI shielding in plastic housings. Deposition is performed in cleanrooms using both flow- and spray-coating processes. GfO mbH, Schwäbisch Gmünd, Germany.
Canted-coil gaskets

An EMI spring gasket made of beryllium-copper wire achieves consistent shielding even during difficult service conditions. The gaskets are composed of a series of inclining coils that deflect independently with a near-constant spring force under compression. The closely aligned coils maintain metal-to-metal contact at the ideal contact pressure even when unequal loads occur. The high deflection and resiliency of canted coils also counteract compression over time. Plating is available to improve the gasket's galvanic compatibility. Bal Seal Engineering Europe B.V., Amsterdam, The Netherlands.
