Arduino Portenta H7 Brings Dev Boards to Production Grade 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 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 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 Testing? What Types of EMI Filters are Best for Passing EMC Testing? When you need to pass EMC testing and your new product is being crippled by a mysterious source of EMI, you’ll probably start considering a complete product redesign. Your stackup, layout/routing, and component placement 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 place in your design, and the right filter can help suppress EMI in a Read Article
Thermal Relief Via Design for Proper Impedance 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/layout, signal integrity Read Article
Why you should be using Concord Pro? Why You Should Be Using Concord Pro Altium Concord Pro™ as a standalone product and brand name has been discontinued and the capabilities are now available as part of our Altium enterprise solutions. Learn more here. 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 Read Article
Top Tips from Experienced Flex Designers 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
Design for testability for PCB designers and manufacturers Designing for Testability in PCB Design: 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

How to Create a Test Point Schematic Symbol and Footprint in Altium Designer How to Create a Test Point Schematic Symbol and Footprint in Altium Designer Bare board testing is like a moment of truth, where your fabricator and your design team determines whether a board passes inspection. Some basic test fixtures and testing points should be indicated in your schematic and your PCB layout, especially when they are critical for evaluating board functionality. So what is the best way to do this? You might rely on your manufacturer to assign test points, but for critical circuit blocks, you should Read Article
