Ever use a Ti X2SON packaged part?

The name stands for "Extra Small Outline No-lead." It's a newish package from Texas Instruments. In my experience, Ti is one of the better companies where testing and documenting manufactureability is concerned. The datasheet for this device [www.ti.com/lit/an/scea055/scea055.pdf] is no...

Do Bolts go on the Bill of Materials Too?

Yes. If you want us to install it, it must go in the bill of materials. For the most part, we solder thru-hole and surface mount components on the PC boards. As pretty much everyone knows, all of those parts... Read more

Multidisciplinary Trivia

I sometimes spend my Tuesday evenings engaging in pub trivia. It's a thing here in Oregon - maybe in other places too. I do okay, but there always seems to be too many sports and contemporary pop culture questions. I'm... Read more

Enough with the parts issues already!

I really need to get back to writing about techniques and technology, but today, it's parts again. Parts pricing, specifically. We have some tariffs coming up on parts imported from China, starting on July 6th. Specifically, a 25% tariff will... Read more

Top 5 Ways to Mitigate Component Availability Problems

Most of the electronics design world is by now aware that we're in a very serious period of components shortages. The hardest hit seem to be ceramic capacitors, but other passives as well as a variety of connectors and silicon... Read more

Embedded Passives

I recently participated in the Altium pod cast where I discussed the origins of Screaming Circuits, some DFM hints and a few other topics. I was discussing some of the challenges everyone is having these days in procuring components and... Read more

What is your supply chain telling you about packages?

Have you purchased any electronics components lately? Have you tried and failed to do so lately? Allocation is the word of the day and substitutions are your friend. Many, many parts are in short supply, or unavailable with extraordinarily long... Read more

A Question on Schematic Style

Just a quick question here... I'm placing the components for my TinyFPGA based stepper motor controller board (see the prior articles here first, here next, and here last). Specifically, I'm finding places for all of the capacitors. That's where the... Read more

The QFN Rides Again - a Brief Update

If you've been following this series, you've likely come to the determination that I've fallen behind, or forgotten about the project. I haven't forgotten, but I have fallen behind. When I last wrote about the project (here), I had examined... Read more

5 Reasons Screaming Circuits is Screaming Forward

As most of you likely know, I was recently interviewed by reporter Bill Thomson from the industry journal, AFI International. It wasn't one of my usual interviews focusing on usage of new component form factors, general design for manufacturing, or... Read more
