Conductive grounding from Chomerics provide EMI protection by establishing low impedance ground paths between electrically conductive elements in a chassis or component. These stabs forestall interference from the surface currents that “excite” metal components and thus create “phantom” fields. The tabs can be used to provide the required grounding paths economically as … [Read more...]

Crucial RF Shielding Selection Considerations
Gary Fenical Laird Technologies INTRODUCTION Designers must attenuate RF signals for various reasons. Since a product cannot be legally marketed unless it meets EMC requirements, designers must curtail RF signals above a certain limit. It is important to consider RF shielding materials at the beginning of a design project because choosing the correct kind of shielding upfront … [Read more...]
EMI Shielding and Optical Enhancement to Touch Screens
Electromagnetic attenuation features can be incorporated as an integral part of touch screens rather than as a separate component in those display applications requiring shielding for EMI/EMC compliance. Various enhancement techniques and design considerations will be reviewed. Features and methods employed will vary with particular touch screen enhancements and will include … [Read more...]
PCB Board Level Enclosures: A Vital Design Element
PCB design is vital to the efficacy of innumerable electronic products. A reliable product and marketplace success are the ultimate rewards for careful consideration of all design issues. Choosing an appropriate board level enclosure is just one element of successful design efforts, and the choice must be carefully considered along with other crucial issues including the … [Read more...]
Understanding Shielding Effectiveness of Materials and Measurements in the Near-Field and Far-Field
When we treat the shielding effectiveness measurement with a uniform field, the results are similar for both near and far fields. Kermit O. Phipps and Philip F. Keebler EPRI EMC Laboratory, Knoxville, TN, USA INTRODUCTION Traditionally Schelkunoff’s shielding effectiveness equation is used universally in teaching and practice throughout the EMC community as a whole. In this … [Read more...]
Magnetic Shielding Design for Manufacturing
Sensitive electronic devices require protection from radiating magnetic fields. David Grilli Magnetic Shield Corporation, Bensenville, IL, USA Magnetic shielding for static and low frequency (<100 kHz), time-varying magnetic fields is accomplished by containing a specific device or item within a sheet metal enclosure of high permeability material. Typically, a sensitive … [Read more...]
