A common question in new product development is, “How do I properly ground the heatsink?” As a practicing compliance professional, this is an important question to have at least an idea of how to respond.

This month’s column is the last of three parts devoted to designing, testing, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

This article introduces typical latch-up verification techniques to detect and prevent latch-up. These techniques rely on electronic design automation (EDA) tools to deliver the coverage necessary to identify and eliminate latch-up risks. 

This year, 2022, is a revision cycle year for ANSI Z535, and it marks the first time many of the standards have changed in over a decade. This month’s column explores the latest updates and what they mean for product safety.

Search and rescue transmitter interferes with car alarms, central locking, and garage door openers in Las Vegas.

This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

When handling ESD-sensitive components, we must protect them from ESD damage.

Walkie-talkies interfere with electronic door locks on aircraft cockpits.

A common problem experienced by novice oscilloscope users is the inability to effectively capture signals we're trying to measure.

This is the first of three articles devoted to the design, test, and electromagnetic compatibility (EMC) immunity evaluation of multilayer PCBs containing analog circuitry. In this study, there are seven design variants that all contain a similar schematic but implement different PCB layout techniques.
