PCB Via Current-Carrying Capacity: How Hot is Too Hot? One common question from designers, particularly new designers that are learning about industry standards, is current-carrying capacity of conductors in a PCB. Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool. While the recommended Read Article

Amplifier Stability at High Frequencies and Stray Capacitance Amplifiers are one of those critical components that make modern life possible. From wireless communication to power electronics, amplifiers need to run stably and predictably for these products to work properly. Stability analysis is one of my favorite topics in physics and engineering, and it always tends to crop up in places you would least expect. One of these places is in amplifiers. Any time-dependent physical system with feedback and gain Read Article

Near-field vs. Far-field EMI: What's Causing Noise Problems in My PCB? If you’re an antenna designer, then you’re likely familiar with all aspects of near-field vs. far-field radiation. Given the litany of radiated EMI problems that cause noise within and outside of an electronic device, one might suddenly realize their new product is acting like a strong antenna. To understand how EMI affects your circuits, it helps to understand exactly how near-field vs. far-field radiation from your PCB affects your ability to Read Article

The Great PCB Layout "Rules of Thumb" Debate Rages On To this day, I still see many PCB layout “rules of thumb” that first became common nearly 20 years ago. Do these rules still universally apply? The answer is a firm “maybe.” Many of the conversations you’ll see on forums regarding PCB design rules devolve into an always/never discussion, causing some designers to use or ignore common design rules in situations where they may not apply. In some cases, this will not cause a board to fail. As some Read Article

ADC Sampling Rate and Layout for Mixed Signal Boards Whenever you’re selecting an ADC, whether it is built into an MCU or as an external component, the sampling rate is a prime consideration, as it will determine how well you can reproduce a measured signal. RF applications, analog sensor boards, and other mixed-signal devices will need at least one ADC with an appropriately chosen ADC sampling rate. If you’re designing with a mixed-signal board, you’ll need to balance the required signal bandwidth Read Article

Sharing PCB Data with Manufacturers in the Cloud Once you’ve finished your new project and you’re ready to push it to your manufacturer, you’ll normally be stuck in an endless email chain with an engineer, or you’ll have to share cloud links with each other. Personally, I find the long email chains and long list of links overwhelming, especially when I have plenty of other tasks that require my attention. Sharing PCB data with manufacturers shouldn’t be a headache, it should be a seamless Read Article

Getting Started in Altium Designer | Changing the Rules! The Altium Designer environment is controlled by rules, which are created using a powerful tool called the “PCB Rules and Constraints Editor”. By creating rules before component placement and routing starts, Altium can warn you or prevent you from making mistakes, depending on how your preferences are set. If rules are changed midstream, Altium’s sophisticated Design Rule Checker can highlight violations based on the revised rules, and report Read Article

Industry 4.0, Artificial Intelligence, and IoT in Manufacturing When it comes to electronics, consumer devices like smartphones and Alexa tend to get all the attention. However, according to Alun Morgan at Ventec International Group, “about 23% of PCBs produced worldwide are used in electronics equipment for manufacturing applications.” The numbers only go up when you include other non-consumer categories that support manufacturing operations, such as automotive, telecom, power generation/distribution, and Read Article

Lane Recognition and Tracking with NVIDIA Jetson Nano Autonomous vehicles are slowly becoming an important part of the automotive industry. Many believe fully autonomous vehicles will soon be driving alongside humans, and technology companies are in a race to deploy fully autonomous vehicles. In December 2018, Waymo, the company that emerged from Google’s self-driving car project, officially started its commercial self-driving car service in the suburbs of Phoenix. Companies like May Mobility, Drive Read Article
