PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

The End is Near - X30

Let me be more specific. The end of the year 2018 is near. Some might argue that with air conditioning to keep us cool in the summer, heating to keep us warm in the winter and an industrialized global food... Read more

Sometimes, I just want to build it myself

It should (and does) stand to reason that I'm a big fan of professional assembly. When you need it done right, or need a bunch built, there's no better way to get working PC boards than a solid professional assembly... 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

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

Make that Three QFNs

It's a new weekend, and I'm back to my obsession with stepper motors. If you haven't read part one of this series yet, go back and read it here. That's not an order; more of a plea. In any case,... Read more

A couple of QFNs and Circuit Maker CAD software

It's about time for another project. I normally design half a dozen or so small boards per year. It's not my profession. It's just something I do. But I haven't designed or built anything since the "incident" with the photo... Read more

Twelve Things that started in 2017 and will finish in the next decade or so

It seems like not but just a year ago, I was already forgetting to write a new year's prediction blog post. If that didn't make much sense, then likely neither did my predictions post from a year ago. I started... Read more

Merry Mosfet!

What is Mosfet day and why should you care? Mosfet day is a holiday, on December 23rd of each year, all about celebrating what we are collectively capable of doing, if we set our differences aside, if we look at... Read more

Five traps to avoid when changing from hand assembly to machine assembly

In the past, it was usually pretty easy to find chips in both surface mount and thru-hole packages. Somewhere in the last decade or so, component manufacturers stopped introducing thru-hole versions of their newest chips as standard practice. In many... Read more
