PCB supply chain What is the PCB Supply Chain? The PCB supply chain encompasses all portions of PCB manufacturing processes, reaching from raw materials to components. Learn more about the PCB supply chain in our guide. Read Article
Meeting Standards: IPC 6012 Class 3 Annular Ring Meeting Standards: IPC 6012 Class 3 Annular Ring Take a look at the above image of a PCB layout, specifically the vias and drill holes poking through the silkscreen. It's quite clear that some of these vias are off-center, meaning the drill hit that created these vias was not dead-center in the receiving land. This leaves behind an annular ring, something which might be considered a defect in certain IPC product classes. Under the IPC standards for rigid boards, we have several possible Read Article
Everything You Need to Know About Ferrite Beads Everything You Need to Know About Ferrite Beads As noted in my previous blog regarding PDS design, the whole power supply conundrum is one that has been plagued over the years with a number of erroneous rules-of-thumb; “black magic” design rules and confusion as to what does or doesn’t work. One of the most controversial topic areas focuses on the use of ferrite beads as a means of controlling and containing EMI. There is conflicting information concerning the use of ferrite beads and it is Read Article
Tout ce que vous devez savoir sur les perles de ferrite Tout ce que vous devez savoir sur les perles de ferrite Comme indiqué dans mon précédent article de blog sur la conception de PDS, l'énigme de l'alimentation électrique a été entachée par un certain nombre de règles de base erronées au fil des années. Cela a créé une certaine confusion quant à savoir ce qui fonctionne et ne fonctionne pas. L'un des sujets les plus controversés concerne l'utilisation de perles de ferrite comme moyen de contrôler et de contenir les EMI. Il existe des informations Read Article
Tutto Quello che c'è da Sapere sugli Anelli di Ferrite Tutto Quello che c'è da Sapere sugli Anelli di Ferrite Come ho espresso nel mio precedente articolo sulla progettazione del Power Delivery System, la progettazione dei sistemi d’alimentazione è stata complicata nel corso degli anni da una serie di regole empiriche errate, consigli di dubbia provenienza e una grande confusione su cosa funzioni o meno. Uno degli ambiti più controversi riguarda l'uso degli anelli di ferrite come strumento per controllare e contenere le EMI. Esistono informazioni Read Article

Advanced Design Techniques with Altium Designer Advanced Design Techniques with Altium Designer In this article, we’ll learn how to use Altium Designer® to implement extra functionalities that are not available by default. We’ll discover a powerful aspect of Altium Designer that when mastered can bring your design skills to a higher level. In this article, we’ll discuss how to implement a script to perform design verification for you. We will learn: How to create rules to verify some design requirements. To verify those rules using a script Read Article
Know the Bandwidth Know the Bandwidth This article relates to both printed electronics and PCBs. I acquired my bandwidth design techniques working in PCB design, and later applied the same principles to my printed electronics design. In this article, I’ll explain my knowledge of bandwidth, and how I was able to apply it to both PCBs and printed electronics. Before going into details on bandwidth, I think it’s worth revisiting what we in electronics mean by the term “signal”. For me Read Article

High Performance Sub 1GHz RF Project High Performance Sub 1GHz RF Project This week, I’m building a high-performance sub-1GHz transceiver that I want to use as a standalone Internet of Things node using the ARM Cortex M3 microcontroller. As with my other projects, this project is open source and published on GitHub for you to use as the basis of your own design, or to use as-is. The RF schematic and layout are production proven, as are the microcontroller schematic and all footprints on the board. However, do keep in Read Article
PDN Analyzer Quick Start on a Motor Driver PCB PDN Analyzer Quick Start on a Motor Driver PCB Previously, I posted about designing a simple DC brushed motor controller using a single IC. While it’s a relatively simple board, it will still be transferring a maximum of 4 amps of current if both motors are running at the driver’s full rated current per channel. For a board as simple as this, you could simply look at the trace length and width and use an online calculator (or a little math) to figure out current densities on the traces and Read Article
What is the Return Current Path in a PCB? What is the Return Current Path in a PCB? Do you know how to determine the return current path in this PCB layout? One of the fundamental aspects of any circuit diagram is the return current path. In a circuit diagram and a schematic diagram, the path that electric current follows to return to the low potential side of a power source should be obvious, but it may not be so obvious in a PCB. To quote the great Eric Bogatin at his PCB West 2019 presentation, the distinction between a Read Article
How to Use Altium Designer Most Efficiently How to Use Altium Designer Most Efficiently One of the things I really love about Altium Designer® is how many shortcuts there are, and how customisable they are. A while ago in my database library’s chat channel, there was a really good discussion about shortcuts and how each of us customises his or her menus to be able to draw schematics and layout boards as quickly and efficiently as possible. Many of us use and love similar shortcuts, but there were enough interesting use cases that I Read Article
Injectsense Real-Time Eye Pressure Monitoring Injectsense Real-Time Eye Pressure Monitoring A prototype of Injectsense's wireless silicon sensor module next to a grain of rice and a quarter (Image source: Injectsense) A little over a year ago, I noticed that things sometimes got a little blurry while I was looking at my computer screen. My cousin Graham in England has macular degeneration, which has left him almost totally without sight. I have to admit that the thought this might happen to me was lurking in the back of my mind, so I Read Article
