Part 1 of this two-part article explores some basic rules for terminating cable shields. Part 2 of the article will appear in our October 2022 issue and will summarize the results of recent testing conducted by the author on the shielding effectiveness of screened cables up to 2.8 GHz
This article provides a high-level overview of the Industry Council paper “Survey on Latch‑up Testing Practices and Recommendations for Improvements,” which describes the full analysis of the collected responses and lays a path for potential adaptations needed to accommodate its use in future technologies and applications.
Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.
