Designers and manufacturers of electronic products are frequently faced with the question: “How do I find a high-quality EMC testing laboratory where I can confidently test my products?” The emphasis of the great majority of design and/or manufacturing entities is on obtaining (1) quality preliminary testing of EMC characteristics to refine the design of their products and (2) quality final design testing of their product for regulatory approvals. The final design, of course, is what gets manufactured and released to the general population for their use in daily life. This article is intended to aid designers and manufacturers in finding and utilizing high-quality EMC testing laboratories.

The immunity to ESD of present-day electronic components and devices has further decreased due to the high sensitivity of ICs.

Electronic devices can be exposed to electrostatic discharge (ESD). The discharge process generates rapid electric and magnetic processes that can impair the function of the electronic devices. Devices are tested for their immunity to ESD using special ESD generators and test setups (EN 61004-2).

This article deals with improving EMC measuring methods that are used during the development of automobiles in the field of interference emissions. Development-stage investigations are normally performed with measuring systems that have actually been conceived for vehicle component tests. EMC measuring methods that are tailored to the development stage, however, are much better suited for this task since they help save time and costs. One such measuring method is presented here as a practical example.

We have all seen advertising copy for test equipment manufacturers’ “EMC receivers” and “EMC test services” provided by commercial EMI test facilities. While we know what the aforementioned receiver does, and what sort of services the test facility supplies, the nomenclature is wrong and is symptomatic of a deeper problem.

The reliable operation of complex electronic communications, control and armament systems in extreme environments demands stringent design criteria and careful validation. Severe shock, vibration, heat, humidity and airborne contaminants are common in land, sea and air platforms.

The new center at the Grand Valley State University in Michigan is pairing engineering students with local companies to assist in developing and testing new products that will eventually enter the market.
