Stopping Electromagnetic Interference At The Printed Circuit Board By Dr. Robert G. Kaires
The job of the PCB designer is two-fold. First, don’t inadvertently build an antenna into the PCB (printed circuit board) itself, and second, don’t allow excessive energy to be channeled onto the external antennas. This article looks at things that can be done at the PCB level to improve or preempt electromagnetic interference (EMI) problems.

The Facilities Manager’s Guide To ESD Flooring Materials By Dave Long
Many facilities managers agonize unnecessarily while attempting to choose the right ESD floor for their corporate environments. To solve the problem, a growing number of high tech businesses are selecting different types of flooring for different parts of their businesses, often utilizing architects to help them create a functional, attractive and well integrated environment.

Performing Safe And Accurate Dielectric Withstand Testing In A Production Environment By Dwayne M. Davis
Performing a routine product safety test should not in itself represent a shock hazard to the test operator. Yet, when working with an energized circuit, an operator must be aware of the hazards involved in performing the test and take the necessary safety precautions.

Selecting Material For Shielded Enclosures By Praveen Pothapragada
The range of reasonably priced materials that can be used for shielded enclosures has increased substantially. Choosing the proper material can save much effort and money. Yet, too often, engineers tend to specify only materials with which they are familiar. Simple mathematical calculations that can take no longer than an hour to compute may be all that is needed to get a project off on the right foot.
