Production-Grade Battery Modules for Raspberry Pi Zero I’ll admit, I’m a big fan of Raspberry Pi. This set of inexpensive boards packs plenty of general purpose computing power into a small form factor, it easily connects to a LAN/WiFi and is accessible via SSH, and its memory is easily expandable with a micro SD card. It’s also easy to get a new prototype embedded application up and running directly from your laptop. The one aspect that prevents its application as a production-grade embedded system Read Article
PCB Design Review and Collaboration in Altium Concord Pro Remote collaboration tools are everywhere these days, and now designers have access to a convenient collaboration system for electronics design. Whether you’re part of a design team, or you need to quickly execute any design changes recommended by your manufacturer, you need cloud collaboration tools that are immediately accessible within your PCB design application. Now with Altium Concord Pro, you’ll have access to a cloud-driven design Read Article
Differential Pair Length Matching: Best Practices for Signal Integrity Take two signals and send them down a parallel bus or differential pair. How can you be sure the downstream receiver will latch to your signals? If your signals don’t arrive at the same place and at the same time, then gates in your receiver won’t latch at just the right moment. This delicate balance can be like walking a tightrope across a cliff, and it can be difficult to maintain differential pair length matching by eyeing your trace lengths Read Article
How Do Pads and Vias Impact Total Capacitor Parasitic Inductance? In this blog article we discuss how the footprint and mounting style affect capacitor parasitic inductance. The pads and vias back to the PCB power planes increase the total series inductance of the capacitor. Read Article
An Overview Of PCB Outer Layer Processing Expert Kella Knack describes in detail the fabrication of the PCB outer layer. Read and learn about how different vias are formed and the steps involved in the multilayer build-up process. Read Article
The PCB Fabrication Process—What Every Design Engineer Needs To Know, Part 1 In the olden and not-so-olden days of PCB development, the process of moving a board from design to manufacturing was often referred to as “throwing the design over the wall.” This was not the result of the operations being so clearly divided, but rather a way to assign ownership and blame if there were errors. My last project at Martin Marietta was a black hole program for the U.S. Airforce and Navy. When problems were encountered during the Read Article
Working with Design Variants Introduction They say variety is the spice of life. That is also the case for PCB designs. It may come as a shock to some, but many companies are in business and always chasing this thing called “profits” (I am using my sarcastic voice). It is entirely understandable that profit is what keeps the doors open and people employed. A significant way that they improve the bottom line is to have a variety of product lines available to their customers Read Article
Arduino Portenta H7 Brings Dev Boards to Production Grade When I hear the name “Arduino,” I don’t usually think of production-grade hardware. I’m not talking down to the folks at Arduino, they’ve done an excellent job at invading the educational and proof-of-concept development niches, to the extent that other hardware platforms simply haven’t been able to catch up. Arduino boards are an excellent choice for low volume functional prototyping and embedded software development. But what about production Read Article
Open Source Ventilator Project (OSV) Combats Ventilator Shortage Dugan Karnazes joins the OnTrack Podcast to discuss his work with the Open Source Ventilator project, and its effort to end the ventilator shortage. Read Article
GaN MMIC Power Amplifier Market Outlook and Applications The next smartphone you buy is likely to include a GaN MMIC power amplifier for wireless communication. What was formerly relegated to academia is now seeing fast commercialization. These developments aren’t limited to smartphones, although this is expected to account for a significant portion of the growing RF components market. High frequency radar in automotive, aerospace, and even robotics is expected to be a significant driver of further GaN Read Article
What Types of EMI Filters are Best for Passing EMC Certification? When you need to pass EMC certification and your new product is being crippled by a mysterious source of EMI, you’ll probably start considering a complete product redesign. Your stackup, trace geometry, and component arrangement are good places to start, but there might be more you can do to suppress specific sources of EMI. There are many different types of EMI filters that you can easily place in your design, and that will help suppress EMI in Read Article
Thermal Relief Via Design for Proper Impedance Following DFM guidelines is a critical requirement for ensuring high yields and defect-free boards during fabrication. Most DFM guidelines are well-grounded and do not generally interfere with signal integrity. In the event that they do, most EDA tools include features that can help ensure you won’t sacrifice signal integrity for manufacturability, and the two design aspects often go hand-in-hand. One aspect of routing, signal integrity, and Read Article
Why you should be using Concord Pro? Introduction A journey of a thousand miles begins with a single step, or so the aphorism goes. I think it’s worth noting that the first step is the most difficult to take. In my experience, the best engineers suffer from a condition in which they, before even taking that first step, endlessly consider “What if?” scenarios. You know what I am talking about here... “What if we do this and something happens?” This issue is so prevalent in our Read Article
Top Tips from Experienced Flex Designers Fabrication: In general, advice given about flexible circuit fabrication is split between knowledge of the fabricator and their process, and communication. Knowledge of the printed circuit board fabrication process is not as common as it once was, and this is even more apparent with the subtleties of flex manufacturing. Understanding the manufacturing process helps to illuminate areas that are more challenging for fabrication, as well as areas Read Article
PCB Design for Testability to Ensure High Yield and Quality If you remember your days in school, then you probably remember the feeling of happiness and celebration when you pass a big exam. You’ll feel the same sense of adulation when your board spin passes a barrage of pre and post assembly tests, but a complex design might not reach that stage unless you implement the right design for testability methods. There are some simple steps that can help your manufacturer identify and quickly implement Read Article
A PCB Design Review Checklist Gets You to Manufacturing Quickly From what I’ve heard in some of my favorite podcasts, successful people keep a lot of to-do lists. Likewise, PCB designers can ensure their own successful manufacturing run when they keep a PCB design review checklist. After you send your design data over to your manufacturer, their engineers will go through your design with a fine-tooth comb, looking for anything that could reduce yields or anything that appears as a discrepancy between design Read Article
What Impact will the Coronavirus have on Your Designs? Judy Warner: Mike, we are hearing and watching the tough impact of the coronavirus on the world stage. From your perspective as a globally-focused editor, what are you seeing and hearing that is immediately impacting the electronics industry? Mike Buetow: There is clearly disruption in the supply chain at several levels. Taiwanese-owned factories make up the leading share of bare boards worldwide, at about 34%. About 63% of the output value of Read Article
