Screaming Circuits: Circuit Design

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

All Done and Ready to Go! Or is It?

Most of what I write about here on the Screaming Circuits blog relates to DFM (design for manufacturing) and PCB layout best practices. Being in the business of prototype and on demand manufacturing (POD), we are frequently exposed to the... Read more

PCB TIP OF THE DAY - AVOID COSTLY CONNECTOR MISTAKES WITH PROPER MECHANICAL DRAWINGS

Almost every PCB needs to interface with the outside world in some way or another, or interface with other PCB’s within the internal structure. This means that power and I/O connectors are very common, and unfortunately requirements are commonly overlooked.... Read more

PCB DESIGN TIP OF THE DAY: CLEARLY DEFINE YOUR "KEEP OUT" ZONES

Similar to the connector issue, it’s vital that you clearly define any “keep out” zones intended for aspects such as mounting holes or sensitive circuitry. While you are defining those zones, remember that solder mask isn’t considered a reliable insulator,... Read more

PCB Design Tip of the Day: Connectors - Which Side is Up?

PCB Design Tip of the Day: Ensure Connector Locations & Orientations are Correct Connectors, especially thru-hole connectors, present opportunities for error in both layout and in assembly. First, it's not always obvious to the PCB layout specialist which side of... Read more

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

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

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
