A Second Pair of Eyes

We all know the drill. With fingers crossed and hopes held high, you send your board design off to manufacturing. Unless you’re the world’s most meticulous engineer, your design will get bounced back. In the process of fixing those pesky bugs, a whole lot more errors may work themselves into your original design. In this week’s episode of Fish Fry, we investigate … Read More → "A Second Pair of Eyes"

Where Does an Engineer’s Responsibility End?

EEJournal, as its name implies, concentrates on the bits and bytes or the chips and boards of the electronics industry. But there are times when it seems like a good idea to look at wider issues. And this may be one of them. What has triggered this is a series of news stories that have demonstrated technology failings that have led to broader consequences.

Why Are Design Tools So Bad?

As much as the EDA industry would like us to believe otherwise, it’s almost impossible to find an engineering team who is satisfied with their design tools. More often than not, when chatting with designers about their tools, we get sentiments ranging from “survivable” to “horrible.” The “survivable” end of the spectrum usually amounts to something on the order of, “We managed to get the … Read More → "Why Are Design Tools So Bad?"

Board to the Future

Your mission, should you choose to accept it, is to create a truly unique IoT design. As always, should you or any member of your engineering team be caught or killed, we will disavow any knowledge of your actions. This podcast will self destruct in five seconds… As we all know, IoT designs present us with a unique set of prerequisites and board design challenges. In … Read More → "Board to the Future"

System Delta Sigma Delta

System Design is inherently a task of integration. The job of the system engineer is to gather and integrate a collection of components which, taken together, will solve some problem, while meeting a list of requirements such as form factor, performance, functionality, power consumption, reliability, and cost.

Almost all of the components we choose will be sourced from third parties. Seldom (if ever) these days is there … Read More → "System Delta Sigma Delta"

This time of year is typically set aside for preparation, and this year is no different. We spent November working on a couple of major upgrades to prepare for releases in 2018, one with the way we handle quotes in My Samtec, and the other with how we handle the checkout expe...

“Mommy, Daddy … Why is the sky blue?” As you scramble for an answer that lies somewhere between a discussion of refraction in gasses and “Oh, look—a doggie!” you already know the response to whatever you say will be a horrifyingly sincere “B...

Given that the industry is beginning to reach the limits of what can physically and economically be achieved through further shrinkage of process geometries, reducing feature size and increasing transistor counts is no longer achieving the same result it once did. Instead the...
