EMI/EMC/ESD Vero Technologies manufactures a wide range of standard plastic enclosures. However, if radiation emitted by the housed electronics or their susceptibility to external fields is a potential problem, moulded enclosures offer no inherent attenuation to the passage of electromagnetic fields. To provide screening, Vero Technologies offers three alternative internal coatings that provide varying levels of attenuation at different price points to suit more than 95 percent of possible applications. For highly specialized applications, other coatings are available. For less demanding commercial applications, the lowest cost 50-micron nickel coating provides attenuation of 50 dB at 1GHz. The default coating is a 10 or 20-micron silver-coated copper particle coating, which typically attenuates by 78 dB at 10 GHz. The highest attenuation is achieved using a 22.5-micron silver coating, which gives in excess of 80 dB at 1.5 GHz. It provides an effective shield against RFI and EMI and can act as a ground plane to protect against ESD. The design of the enclosure is important. A tongue and groove structure between the mating halves of an enclosure forms an effective complex path, improving the attenuation performance. Removable end panels are secured into an interference fit slot or, if fixings are used, a conductive gasket should be fitted to the mating surface. The rear face of plastic panels will have to be conductively Vero Technologies Offers New EMC Screening Options for Plastic Enclosures coated, or if aluminum panels are used, the front surface will normally be anodized and the rear left with a natural finish or iridised, a RoHS-complaint conductive finish. Teseq’s Compliance 5 EMC Test Software Adds DO-160 Module for Aerospace Applications Teseq, Inc. has introduced a new aerospace test application for use in its Compliance 5 EMC test software. The DO-160 RF emissions and immunity test module makes set-up and testing fast and easy. Preloaded, standard hardware configurations and limit lines enable users to quickly configure hardware and select the required test. A pre-configured menu system allows users to select various settings including standards, test levels, test methods, modulation settings, leveling methods, limit lines, peak analysis and failure analysis. This new update supports versions E, F and G of the DO-160 standard including conducted and radiated immunity (Section 20) and emissions (Section 21), ensuring that tests can be accurately performed with minimal set-up. Teseq’s Compliance 5 is designed for RF EMC testing, providing an integrated test platform for every RF EMC test requirement. It features a unique multi-user function with administrator control that ensures data integrity. Files can be locked or made ‘read only’ by the system administrator. Compliance 5 enables users to construct specific tests, while giving the administrator overall control to important files. The control feature also allows configuration and equipment details to be stored along with results. Reporting is made easy through Teseq’s ‘Global Report’ function, which automatically places selected information from the test into a pre-existing template. Littelfuse Introduces SP1006 TVS Diode Array For ESD Protection in Ultra-Small Form Factors Littelfuse, Inc. has added the SP1006 series to its TVS Diode Arrays (SPA family) of ESD and surge protection devices. The SP1006 series TVS Diode Array is offered in the 0201 form factor (µDFN-2) and provides ESD protection for electronic devices where board space is at a premium. The SP1006 series is particularly suitable for miniature portable electronics applications such as smart phones, MP3/PMP players, portable navigation devices, portable medical devices, and similar handheld equipment. The new SP1006 series is RoHS compliant and complies with the following standards: ESD, IEC61000-4-2, ±30 kV (contact), ±30 kV (air), EFT, IEC61000-4-5, 40 A (5/50ns) and Lightning, IEC61000-4-5, 5 A (8/20μs). Along with ESD protection (±30 kV, contact) and surge capability (5 A, 8/20 μs), the SP1006 TVS diode array offers minimal capacitive loading with added clamping performance due to its low dynamic resistance of only 0.9 Ω. In addition, the low leakage of <0.5 μA (MAX) at 5 V is designed to maximize circuit reliability and minimize battery drain in portable devices. 20 November/December 2011 www.ElectronicsProtectionMagazine.com http://www.infowebcom.com http://www.infowebcom.com http://www.ElectronicsProtectionMagazine.com
