Testing

The trend of progressively migrating both ESD and EMC immunity from the system/board to the component level is creating unprecedented challenges for the component ESD designer.

Choosing an EMC test lab to work with is one of the most important decisions any electronics design engineer or product developer has to make.

The world of non-food consumer products has undergone significant changes over the past two decades. New technologies and online sales are the primary drivers behind the upcoming new Product Safety law.

This article presents methods for building reduced-order models (ROMs) based on proper orthogonal decomposition (POD) for modeling transient heat transfer in partially-perfuse tissue in prolonged contact with a heat-generating wearable device.

Even though warnings and instructions are not followed by all product users, they are important for product safety and product liability defensibility. Manufacturers must decide how safe to design their products and when they can also rely on warnings and instructions to make the product safe.

This article offers some useful insights and guidelines on how to effectively design and test systems using wide band gap devices to optimize product performance and achieve EMC compliance.

This is the fourth and final article in our series commemorating 70 years since the advent of modern EMC testing.

This updated version of an article originally published in the March 2014 issue provides details on recent and current developments in the ESD testing of electronic products.

This article is the third in a series commemorating 70 years since the advent of modern EMI testing. But this last article is itself divided into multiple parts, due to the topic’s complexity. Unlike the previous two articles, which mainly tracked evolution and explained issues, this series of installments argues that we started off correctly seventy years ago, but then took the wrong fork in the road in 1967.

The electrical engineering sub-discipline of electromagnetic compatibility has been described as the study of second-order effects that were ignored in college.
