EMI/EMC/ESD New Silver Conductive, One Part Aqueous Based Sodium Silicate System for EMI/RFI Shielding Master Bond’s new MB600S is an aqueous based sodium silicate formulated for coating applications where electromagnetic interference/radio frequency interference (EMI/RFI) shielding is required. The energy emitted from various sources, including radios and appliances, can interfere with other electronic devices. Conductive coatings are often applied to the housings in order to protect the devices from these types of interferences. This silver gray colored system is used in a variety of aerospace and electronic applications. Tested according to IEEE 299, 2006 methods, MB600S was as effective as the aluminum reference with a range of 95 dB to 105 dB, from 100 MHz to 2 GHz. Above 2 GHz, the shielding effectiveness of MB600S decreased to 80 dB and slightly below. Above 4 GHz, the effectiveness was 60 to 70 dB. As the system is water based, it is relatively non-toxic and easy to handle. It can be brushed or sprayed with the proper equipment. If sprayed, the shielding effectiveness would be even greater than the values given above. MB600S will cure at room temperature in 24 to 48 hours or in one to two hours at 80°C. It features high temperature resistance with a service temperature range of 0°F to 700°F. The compound is available in glass jars, and has a shelf life of six months in original, unopened containers at room temperature. Agilent Technologies’ 3D Electromagnetic Software Release Targets EMI Compliance Agilent Technologies, Inc. has released the latest Electromagnetic Professional (EMPro), its 3-D electromagnetic simulation software. EMPro 2013 helps design engineers identify and resolve difficult electromagnetic interference (EMI) problems. It also offers a number of new capabilities to reduce simulation time and increase design efficiency. EMPro 2013 allows engineers to simulate the radiated emissions of electronic circuits and components and then determine whether these emissions are within levels specified by common electromagnetic compatibility (EMC) standards, such as FCC Part 15, CISPR 22 and MIL-STD-461F. This capability is enabled by new specification-compliance templates, as well as several enhancements to both EMPro’s finite element method (FEM) and finite difference time domain (FDTD) simulators. “With more electronics being integrated into smaller packages, EMI problems are quickly becoming a leading cause of new product delays,” said Marc Petersen, EMPro product manager at Agilent EEsof EDA. “As a result, designers are now turning to EM simulation to catch these problems early and ensure their designs are compliant with EMI specifications. Our newest EMPro software 20 release provides designers the capabilities they need to address this challenge head on.” EMPro 2013 has several new enhancements including a simulation management tool for launching remote and distributed simulations on high-end servers and compute clusters, disconnecting and later reconnecting a client computer and receiving status updates on a mobile device, increased FEM mesh performance and robustness for large designs, new FEM hybrid boundary conditions that result in higher simulation speed and accuracy. Additional features include a real-time electrical connectivity checking tool in the main geometry modeling window that prevents inadvertent gaps between conductors, a parameterized trace component for modeling IC and printed circuit board interconnects, and numerous graphical user interface enhancements, in the areas of snapping, bending, length measurements, results display and managing large groups of objects. Redesigned Select-A-Shield USB Forensic Pouch Provides High RF/EMI Performance Select Fabricators, Inc. is enhancing its USB Forensic Pouch, making it a high performing “Faraday bag” for the market. PAMS tested at 900 MHz, the pouch delivers more than -80 dB of RF/EMI isolation. Well suited for digital forensic evidence collection, this window touch pouch allows for hands-on manipulation of wireless devices in a secure RF tight environment. With the filtered USB connection, there is no need to take the captured device back to the lab to extract stored data. The Select-A-Shield USB Forensic pouch can be purchased separately or as a complete portable forensic pouch kit. The standalone pouch (RFSP1218) includes a foam insert, cables and convenient and visible evidence collection cards. The mobile forensic kit (RFSP1218K) includes all of the above, plus a durable royal blue sport nylon carry bag that allows usage in all types of conditions including inclement weather. All Select-A-Shield RF isolation pouches are made in the USA starting with two layers of conductive silver/copper/nickel material with a double rollover closure to insure a tight isolation capacity. The conductive material and closure system will maintain shielding performance for hundreds of uses.
