EMC Lab Selection – Revisited

1310 F1 coverDesigners 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.

A Brief History of Electrostatic Discharge Testing of Electronic Products

1403 esd-testing coverWith the inventions of the transistor in 1948 and the Integrated Circuit in 1958, and the utilization of these major breakthroughs in the development of computers and other electronic devices, industry began to worry about and to design components and end-products that could survive the discharge of electrostatic discharges to chips, printed circuit boards, and final packaged-products.

A Historical Look Back: The 1977 CBEMA Paper on Electromagnetic Emanations

In the middle of the 1970s, the United States Federal Communications Commission (FCC) began to look seriously at electromagnetic emissions from electronic data processing (EDP) equipment and office equipment (OE). This growing awareness on the part of the United States telecommunications regulation body was a result of the increasing number of computers being used by society and the increased potential for growth by licensed broadcast services due to the proliferation of electronic-computer sources. The Computer and Business Equipment Manufacturers Association (CBEMA) formed a technical subcommittee to assist in preparing an industry response to the concerns of the FCC. This paper reviews the report developed by that technical subcommittee, made public in May of 1977.
