Remote work and git for hardware development with Altium 365 Breaking Out of the Office with Altium 365 A few years ago, I was working as a PCB design engineer for a company in the stunning Italian countryside, designing power inverters for water pumps. The work was as intricate as it was commensurately fulfilling, with every board presenting an extremely sharp dI/dt and stringent EMC and reliability requirements. Driving to work each day, with the hills slowly emerging from behind the freeway to reveal the tiny dot that was our factory, was scenic Read Article

What is Burn-in Testing for Electronics? What is Burn-in Testing for Electronics? Once you’re planning for production of any new board, you’ll likely be planning a battery of tests for your new product. These tests often focus on functionality and, for high speed/high frequency boards, signal/power integrity. However, you may intend for your product to operate for an extreme period of time, and you’ll need some data to reliably place a lower limit on your product’s lifetime. In addition to in-circuit tests, functional tests Read Article
PCB Via Current-Carrying Capacity: How Hot is Too Hot? 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 regarding the 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 Read Article

Bluetooth 5.1 SoC vs. Module: Which is Best for Your Design? Bluetooth 5.1 SoC vs. Module: Which is Best for Your Design? The list of features available in Bluetooth just got a little longer since the release of Bluetooth 5.1. Component manufacturers have taken this mobile technology to the next level for IoT devices by integrating wireless comms with an MCU for embedded processing. This is just another step in the continuous push to pack more functionality into a smaller footprint. If you want to incorporate a Bluetooth 5.1 SoC into your new product, you have two Read Article

PCB Mountable Connectors: SMD vs. Through-hole PCB Mountable Connectors: SMD vs. Through-hole When I designed some of my first boards, I was always working at DC or low speed, and any signal integrity problems from my connectors were an afterthought. These initial boards were for low frequency measurements of an electrochemical sensor. The only circuitry involved was a low-pass filter circuit with through-hole passives, a PCB mountable connector for a lab-grade power supply, and a parallel connection to an SMU. After learning the finer Read Article
Designing Pressure Tolerant Electronics: It's All About Mechanics Designing Pressure Tolerant Electronics: It's All About Mechanics After a recent inquiry from a customer about a high power board that must withstand high gas pressures, my team suddenly realized we needed to do some research on designing pressure tolerant electronics. This area is not as popular as designing electronics for ambient pressures, but the design techniques used here enable important scientific expeditions and industrial applications in high pressure environments. Whether the board will be placed in Read Article
High Voltage SMPS PCB Layout to Minimize Heat and Noise High Voltage SMPS PCB Layout to Minimize Heat and Noise Whether you are performing AC-DC conversion or DC-DC conversion, switching power supply layouts are common in high voltage design and must be constructed carefully. Although this system is quite common, it will easily radiate EMI due to the fast changes in voltage and current during switching. Designers can rarely adapt existing designs into new systems as a minor change in one area can create an EMI problem that is difficult to diagnose. With Read Article
How to Select an Inductor for a Buck Converter How to Select an Inductor for a Buck Converter An SMPS is one of those quiet (yet electrically noisy) devices that makes your favorite electronics run smoothly. They sit in the background quietly doing their duty, yet your board wouldn’t operate without them. As part of DC-DC converter design for power-hungry applications, component selection is quite important for ensuring stable power delivery to a load with high efficiency. Among the numerous DC-DC converter topologies, a buck converter Read Article
Driving Haptic Vibration and Feedback in Wearables Driving Haptic Vibration and Feedback in Wearables Augmented reality, virtual surgery, limb replacements, medical devices, and other new technologies need to incorporate haptic vibration motors and feedback to give the wearer a full sense of how they are interacting with their environment. Unless these cutting-edge applications include haptic vibration and feedback, users are forced to rely on their other four senses to understand the real or virtual environment. Low cost components to support Read Article
Modeling Copper Foil Roughness in Altium Designer's Impedance Profiler Modeling Copper Foil Roughness in Altium Designer's Impedance Profiler Advanced transmission line models for long interconnects require that designers include copper foil roughness calculations in order to determine accurate impedance. Without the right models or design software, you’ll be left to estimate the skin effect impedance, dispersion, and parasitics in your PCB. These models can be difficult to work with by hand if you’re not mathematically inclined, but the right design tools can be used to quickly Read Article
High-Speed Signal Routing: The 5 Important Constraints High-Speed Signal Routing: The 5 Important Constraints Your modern digital board is most likely classified as high speed, regardless of whether you looked at the datasheets for your components. Designing your board successfully will take some important steps when you begin your design. Aside from floorplanning and stackup design, your routing strategy will need to operate within some important constraints. After you capture your schematic as an initial layout and create an initial component Read Article
