Banana Skins – July 2022 (#385-393)
Search and rescue transmitter interferes with car alarms, central locking, and garage door openers in Las Vegas.
Evaluation of PCB Design Options on Analog Signal RF Immunity using a Multilayer PCB
This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.
ESD in Joe’s Garage
When handling ESD-sensitive components, we must protect them from ESD damage.
Banana Skins – June 2022 (#383-384)
Walkie-talkies interfere with electronic door locks on aircraft cockpits.
Evaluation of PCB Design Options on Analog Signal RF Immunity Using a Multilayer PCB
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.
Low Voltage Charged Device Model (CDM) Testing at a Crossroads
Most ESD experts consider CDM testing to be the most critical ESD qualification test for modern integrated circuits. ESD control engineers need to know the charged device ESD robustness of all components passing through their manufacturing line. CDM measurements provide that knowledge.
Estimating the Parasitics of Passive Circuit Components
This article presents a simple method of estimating the parasitics of the three passive circuit components (R, L, C).
Indium-gallium-zinc-oxide (IGZO) Thin-film-transistors (TFT) and ESD
The thin-film transistor (TFT) became commercially available slightly more than 30 years ago in the form of a switch for the Liquid Crystal Display.
Product Manuals in Focus
Read an interview with Dr. Robinson for context on manuals, including the latest standards and best practices for incorporation with your product safety strategy.
Evaluation of EMC Emissions and Ground Techniques on 1- and 2-layer PCBs with Power Converters
This is the 10th and the final 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.
