TCAD Modeling for ESD

TCAD simulation can identify ESD relevant effects and the internal operation of a device under ESD stress conditions that are not generally accessible through conventional measurement techniques. TCAD simulation can help to reduce IC and device design cycle times, resulting in the more timely introduction of innovative products to market.

Mexico Lithium-Ion Battery Standard Takes Effect

A new standard applicable to the testing and labeling of all lithium-ion batteries imported...

Technology Developments and the Risk of Product Liability

The risks of product liability sometime affect technological developments in hardware and software used to make products. They can stifle innovation and make some advancements seem too risky. How does the law view these products and what can be done to evaluate and reduce these risks.

De-risking Resonances in Single Conductor Structures, Such as “Ground”

In this article, the author will identify two major types of single-conductor structure resonances and describe some case studies for both. He will then describe how design projects can quickly and easily be ‘de-risked’ from the possibilities of suffering either type of resonance by the use of low-cost field and circuit simulators and/or low-cost bench testing on physical ‘mock-ups’.

Impact of a Decoupling Capacitor in a CMOS Inverter Circuit

This article discusses CMOS inverter switching and shows the impact of a decoupling capacitor on the power rail signal integrity and radiated emissions.

Qualifying ESD Flooring

Controlled environment testing of static control flooring in combination with multiple forms of ESD footwear during the qualification phase can reveal problems and is a mandatory step to avoid installing non-compliant flooring/footwear systems.

Let’s Talk About Shielding at the PCB Level

This article provides insight into how shielding is used in product development, in particular the effectiveness of shielding when it is applied at the PCB level. 

Designing with Capacitive Touch for Commodity Applications

This article examines the different parts of capacitive touch design and provides a checklist of what to look for when designing a product.

Estimating Reverberant Electromagnetic Fields in Populated Enclosures by Using the Diffusion Model

The authors predict the internal electromagnetic field of a populated enclosure by using the diffusion model, and compare them with the fields obtained by the power balance method, a full-wave electromagnetic solver and measurements, to demonstrate its efficacy.
