The Question What is the required bonding and grounding requirements to achieve compliance with the various electromagnetic compatibility (EMC) standards associated with electronic equipment? I received this question a few days ago and quickly realized that a quick and easy answer was not feasible since I virtually had no knowledge of what kind of equipment types were … [Read more...]
EMC/EMI Challenges for the Connected Car
ABSTRACT Our automobiles are becoming more connected and reliant on wireless connectivity, and at the same time, the number of high-compute internal systems is rapidly increasing. Like any high-speed, complex digital electronic system, automotive electronics can be both a cause of, and highly sensitive to, electromagnetic interference (EMI), and the consequences of failure can … [Read more...]
EMC Simulation for Automotive Ethernet
Introduction The increasing use of electronics in vehicles introduces new risks of interference and crosstalk between components. OEMs and government regulators impose strict limits on electromagnetic interference (EMI) and electromagnetic compatibility (EMC), and redesigning a component that fails to meet these standards can be both expensive and time-consuming. This article … [Read more...]
PC Board Design for Wireless Products
INTRODUCTION TO SELF-GENERATED EMI It seems many manufacturers these days are developing products that incorporate wireless technologies—both in new and existing products. Many of these products are using LTE cellular connectivity and designers are finding that the on-board DC-DC converters and processor/memory bus noise are creating enough broadband electromagnetic … [Read more...]
How to Build Your Own EMI Troubleshooting and Pre-Compliance Kit
Electromagnetic compatibility (EMC) and the related electromagnetic interference (EMI) are some of the obstacles that must be overcome before nearly any electronics product can be brought to market—whether it’s an Industrial Internet of Things (IIoT) device, a consumer electronics product, or military and aerospace equipment. Products must not interfere with one another … [Read more...]
Würth Elektronik Circuit Board Technology Successfully Completes Research Project on Intelligent ARM-Hand Orthosis
In automobile production, industrial robots and production lines largely relieve people of having to work with heavy loads. This is not the case for people who work in a trade or in care, where the body can be heavily burdened by hard work. In the PowerGrasp project, a second skin provides additional strength. Following three years of research, the promising results are now … [Read more...]
Controlling EMI in High-Speed PCB Design
Patrick Carrier - Mentor Graphics, a Siemens Business Antennas come in all shapes in sizes. In addition to wireless communications, they are becoming ubiquitous in the automotive space as well. Similarly, very high speed digital circuits are pervading these realms. It is the unintentional creation of antennas in these high speed digital circuits that cause Electromagnetic … [Read more...]
Conformal Conductive Coating and EMI Shielding
This is a diverse and promising space. In one manifestation, spray-on inks are targeting package-level EMI shielding. Here, they hope to displace sputtering, the incumbent, which benefits from sunk CapEx and lower material consumption costs. They offer low CapEx production in atmospheric conditions and better conformal coverage. Others are developing inkjet printing solutions, … [Read more...]
Review of MIL-STD-464 Requirements
Introduction My reviews have covered MIL-STD-461 over the past few months so it’s time to step up to the system requirements. We realize that the MIL-STD-461 requirements apply to equipment items and subsystems as stated in MIL-STD-464. Revision “C” is the current edition, but a review is a little overdue. In this review, the discussion will focus on the various requirements … [Read more...]
Do Not Miss the EMC + SIPI 2019 Symposium!
In a few weeks, we will be able to enjoy the 2019 IEEE International Symposium on EMC, Signal and Power Integrity (EMC+SIPI). I am so excited! This symposium is sponsored by the IEEE EMC Society (EMC-S), the world's largest organization dedicated to the development and distribution of information, tools and techniques for reducing electromagnetic interference with support … [Read more...]
