This is the eighth article in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques [1-7].
Traditionally, the start of a new year is a time when we reflect on the progress we’ve made during the year passed and set our goals for the new year. We’ve queried training resources in our industry to provide you with an overview of free or affordable solutions to meet your training goals in 2022.
Much has been written about failures due to ground potential rise (GPR), generally in connection with single houses with multiple grounds. But in cases where multiple houses are interconnected via a single piece of equipment, equipment failures could be caused by insulation issues due to GPR attributable to lightning.
The safety hierarchy is a flexible concept that can be helpful in deciding on a final product design. But it can also be a trap for the unwary design engineer. This article will discuss the safety hierarchy concept, how do you comply with its requirements, and what are the problems associated with it?
For engineers new to the field of EMC, the road can look very steep indeed. But, with a plan (and some work!), you can grow from EMC novice to EMC expert.
Overall, latch-up prevention is one of the most important tasks for both foundries and IC designers. Based on the chip design scheme, designers should select proper solutions to eliminate the ILU and ELU risks in chip design, referencing the foundry guidelines and latch-up silicon data to ensure minimal latch-up risks for the product.
History is very telling in influencing the trajectories of product safety and liability. To get the details, we turned to insight from Doug Nix, Managing Director of Compliance inSight Consulting and lead author of the Machinery Safety 101 blog. Read the interview with Nix for context on how the past has shaped the ideology and approaches that we employ today.
Operating my personal document shredder crashes my digital TV set-top box, although it is 5 metres away. Toggling the on/off button on the set-top box restores normal operation.
