How Material Characteristics Factor into High Speed PCB Signal Performance
Evaluating laminates for a particular PCB implementation can be a complex, multilevel process , especially when it comes to the operation of key components on the board, such as high-speed differential pairs. This article will examine some of the factors that come into play with the evaluation process: materials with a low dielectric content versus materials that are low loss; comparing the advantages and disadvantages of each of them; taking

What Happens to PCIe Signals Traversing Blind Vias at Higher Speeds?
In our one, two and three-day courses, which we conduct at technical and trade conferences as well as at private on-site classes, we will frequently be asked about particular technology trends and their impact on current designs. Of late, a number of these questions have focused on how the use of PCI Express (also known as PCIe) at higher frequencies impacts signals that change layers through vias. Limits on the number of vias in PCIe generations

Take Control of the Electronics Life Cycle with Cloud Collaboration
The electronics life cycle is a funny thing in that it relies so heavily on component lifecycles. Despite this relationship, every electronic product lifecycle follows a similar track as any other product. New products start with early adoption, later rise with sustained growth to peak adoption, and fade as new products become available with better features. Once you accept this fact, you can determine how to plan out your design and business

RGB + White LED Strip Controller for Designers
I’ve been playing around with RGB LED strips recently for lighting up my test equipment rack as well as some display shelves. On the display shelves, I have the RGB LED strips behind the shelves, which gives a great definition to the objects on the shelf. But I also want to have a high CRI white LED strip on each shelf to light up the objects. Typical RGBW LED strips available through online marketplaces do not have very good white LEDs, and I’m

Designing a Four-layer PCB Stackup With No Plane Capacitance
At first glance, it might seem that designing a 4-layer PCB should be an easy task, but just like any other board, it requires the right kind of layout and stack-up. Kella Knack gives as an expert advise on how to successfully design Multi-layer stack PCBs.

Silk to Solder Mask Clearance: The PCB Design Rule You Need to Add
I was impressed that, right out of the box, the stock design rule checks (DRCs) in my copy of Altium 20 pretty much covered all the bases on how to make a “standard” printed circuit board (PCB). Altium Designer defaults to “10 mil” rules, which means that the standard spacing and widths of copper tracks is 10 mils. What's more, most of the other spacings also default to 10 mils. This includes track to track, pads to tracks, through-holes to other

How to Calculate Power Dissipation
Understanding the power dissipation of an individual component, an electrical block, or even the whole electronics system is essential for electronics engineers. It is important not only to avoid exceeding the maximum limits of components but also to calculate unknown parameters in input or output sides because power dissipation is related to system voltage and current. In this article, I describe my practices for analyzing power dissipation in

US Department of Transportation Seeking Alternatives to Advanced Navigation GPS
GPS-capable devices range from your phone to your smartwatch; simply type in your destination and follow the directions. Simple, right? According to the Washington Post , we should all stop using GPS as it’s ruining the navigation centers of our brains. Despite the neurological effects on perception and judgment, the U.S. Department of Transportation (DOT) aims to find alternatives to GPS to provide redundancy. What started as a defense

Low Noise, Low EMI Voltage Regulator
A couple of months ago, I purchased an entry-level cinematography camera: the Black Magic Ursa Mini Pro 4.6K G2. I'm planning to use it for project videos, factory tours, and trade show interviews with it mostly being mounted on a shoulder rig. In addition to the camera itself, this requires a surprising number of devices to be powered. To save having lots of batteries to keep track of, I want to run everything off the main camera battery

Best Single Layer PCB Design Software for Your Single-Sided PCB
A one-sided PCB design needs the same attention to detail in its design as a large multi-layer board, it needs Altium Designer. ALTIUM DESIGNER The most powerful, modern, and easy-to-use PCB design tool for professional use. It may seem like the world of PCB design revolves around complex multi-layer high-performance PCBs or other exotic design technologies, but the need for single-sided PCB designs is as great as it ever has been.

Voltage and Current Waveforms on a Series-Terminated Transmission Line
In both of our books, Right the First Time, A Practical Handbook on High Speed PCB and System Design , Volumes 1 and 2, as well as in our on-site and public courses, we talk about the value of a series-terminated transmission line. With this type of transmission line, no power is being used unless the line is being charged up. This enables a lot of computing with a minimum of power. But having a clear understanding of how this type of line

Building the Library - Unified Data Model
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 This may come as a shock to some, but I was raised on a farm back in Pennsylvania. Every spring, we would prepare for the planting season. It was amazing to me to take the seeds, plant them in the field, tend them, and in time end up with a crop. Within

PAM4 Vs. NRZ Modulation Techniques
If there has been one constant about products designed for the internet/networking market spaces, it’s the data rate and frequency of operation at which the technology operates. In some cases, it can be argued that these two dynamics (data rate and frequency) are not necessarily proportional. Still, the former of these meets the criterion of being TNGT (the next greatest technology). With software, the evolution of products is mostly

Altium 365 Library Migration: How it Works and Why You Should Use It
Your libraries are the cornerstone of your PCB design projects. Without them, you wouldn’t be able to load up custom footprints, access schematic symbols, or much else for your PCB projects. When you need to share projects or existing component data with your team, what’s the easiest way to get the data you need without creating long email chains? Before working with Altium 365, we were stuck using tools like Slack, email, an FTP server, Dropbox
