PCB Design Tip of the Day

There’s nothing like a good synonym roll, just like Grammar used to make. AKA Semantics do matter in schematics, especially when dealing with multi-page schematic diagrams, reusing schematic sections or working on a team project. Tip of the day: Use... Read more

PCB Design Tip of the Day

It's often the little things, the seemingly obvious small traps that leap out and bite two weeks later. Mark, PCB design expert from our San Diego PCB Phoenix office has another piece of advice for you when getting your schematic... Read more

PCB Design Tip of the Day

Where do the PCB Design errors grow? A lot has to happen before a PC board gets into an end user's hands - many different processes and people are involved in getting a device designed and built. The more people... Read more

No Open Vias in or near pads

The term "via" probably comes from the Latin word meaning "road." Therefore, open via would essentially mean "open road." Open roads, here in Oregon sometimes run through open range ranch land. That means that cows have as much right to... Read more

Downsizing with SnapEDA

Earlier this year we built the electronic badges for the Open Source Hardware Summit. The badge was very nice as is, but I extended it with a LiPoly battery pack of my own design. The badges were assembled in our... Read more

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...

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
