Fundamentals

In Part 2 of this series we indicated that a key element in a successful static control program was the identification of those items (components, assemblies and finished products) that are sensitive to ESD and the level of their sensitivity. Damage to an ESDS device by the ESD event is determined by the device’s ability to dissipate the energy of the discharge or withstand the current levels involved. This is known as device “ESD sensitivity” or “ESD susceptibility.”

Military EMC design can be particularly vexing. Multiple environments combined with multiple threats lead to multiple requirements. The threat levels, and the resulting requirements, are usually more stringent than found in the commercial world.

Unlike so many technologies in use today, horn antenna history actually started more than a hundred years ago. This short article introduces the reader to the history of horns from the early experiments of radio pioneers to the “horn boom” during the 1940s and 1950s. The article ends with the latest evolution of horn antennas.

Your static control program is up and running. How do you determine whether it is effective? How do you make sure your employees follow it? In Part 3, we suggested that there were at least nine critical elements to successfully developing and implementing an effective ESD control program. In Part 4, we will focus on two more of these elements: training and auditing.

Here are the most likely reasons why, along with the forgotten available 5 GHz band.

Wireless networks offer the convenience of not worrying about being tied to various cables, switches, etc., but they also need to be understood according to their limitations.

Most manufacturers of electrical and electronic equipment have some sort of a regulatory compliance program. These may be part of the company’s internal procedures, a subscription to a compliance related database or various bits and pieces of information held by key people within the organization. No matter how complex or simple, it is imperative that management involved in global regulatory compliance issues have the right information needed to make their programs work efficiently.

Product liability has created problems for manufacturers and product sellers for many decades. These problems have been exacerbated by the expansion of product liability laws throughout the world. In addition, there has been a proliferation of safety regulatory requirements, starting in the United States and then moving to the European Union. In addition, countries such as Japan, China, Australia, Canada, Brazil and South Africa have all recently established or strengthened their product safety regulatory regimes and requirements.
