What Goes into PCIe 5.0 Layout and Routing? Here are some PCIe 5.0 layout and routing guidelines for your next high speed add-in card and motherboard to support PCIe 5.0 devices. Read Article The Importance of PCB Documentation When it comes to real estate, it’s all about location, location, location. When it comes to ensuring a PCB will be built as designed, the emphasis is on documentation, documentation , documentation. This article describes the documents that need to be provided by the board design group to the fabricator, assembler , and test organization. Included is the description of the different drawings needed along with files and notes. All of these Read Article Through Thick And Thin — How Do You Get High Current Into a High Speed PCB? The typical large currents in today’s high speed PCB designs require a different approach. This article will describe the stackup requirements associated with these very large current PCBs and how to design them so that they can be readily manufactured properly. Read Article How Vias Can Affect Very High-speed Signals In a variety of articles posted on Altium’s resource center as well as in several other technical articles, papers, and conference proceedings, the advantages of differential signaling and its ability to deliver very high data rates have been touted. But, as with many things in life, those things that are beneficial can also have a downside. Such is the case with today’s products that deliver 32 Gbps and above data rates and the vias that are Read Article A Short Tour Through The PCB Design Process In several previous articles, I have addressed the PCB design process in terms of the tools involved, the basics of electromagnetic behavior on transmission lines , signal integrity , power delivery design and numerous other PCB design-related topics. But, one of the most important basics is to have a good sense of the factors that are considered to have the fastest design flow. This info spans the buses and types of signals including operating Read Article Bandwidth Requirements For Single-Ended vs. Differential Signals This article provides an overview of the benefits of differential signaling and how it operates in a working electronic product. Read Article The Switching Behavior Of A Series-Terminated Transmission Line Series-terminated lines and differential signals serve as the links in all CMOS devices . While I have written extensively on differential signaling, its operations and its benefits, I have not addressed the switching behavior of a series-terminated line. That is the purpose of this article. The Basics The salient points about a series-terminated transmission line include the following: In this type of transmission line, a series termination is Read Article Developing a PCB Testing Procedure for New Designs As noted in several of my previous articles, at Speeding Edge, we are big proponents of putting test structures into PCBs. The impetus for incorporating these structures covers a wide variety of topics—it’s a new design; you’re using new component technology; a new laminate or a new fabricator to name a few. There are many critical performance characteristics required of today’s electronic products. They operate at high frequencies, move enormous Read Article Altium Concord Pro: Real-time PCB Component Traceability for All Requirements 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 . PCB designers and project managers in highly regulated industries face a number of obstacles when managing the design process and preparing for manufacturing. Aside from paying attention to industry standards, and performance requirements, and coordinating electrical Read Article Modeling PCB Interconnects as Causal Systems Real PCB interconnects are causal systems and must be modeled with the correct time-dependent behavior. Read Article IoT PCB Design: It's More Than Just Hardware Development Altium 365 makes IoT PCB design and coding easy. Share your designs, control revisions, and fork projects directly in Altium Designer or through Altium Concord Pro. Read Article The Benefits of High-Dk PCB Materials The terms “high-speed design” and “low-Dk PCB laminate” are often used in the same articles, and often in the same sentence. Low-Dk PCB materials have their place in high speed and high-frequency PCBs, but high-Dk PCB materials provide power integrity. Low-Dk PCBs are typically chosen as they tend to have lower loss tangent. Thus high-DK PCB materials tend to get overlooked for high speed and high-frequency PCBs. When we look at power integrity Read Article The History and Use of Cross-Hatched Planes Read to learn all about hatch ground in your PCB instead of using ground planes. You'll learn about how this type of ground region impacts signal integrity. Read Article Which Capacitor Types Should You Use? Capacitors are used in far more applications than just bypassing noise, and there are many more types of capacitors than just ceramic and aluminium electrolytic. Read Article A Guide to Challenging Projects Starting a project? Here's an expert advise from Mark Harris to get you through challenging design projects. Read this blog and see if this method will work for you. Read Article The Increasingly Important Role Of Dielectric Loss Tangent In PCB Laminates Learn more about dielectric loss tangent, the role it plays in high-speed designs, and how it varies as a result of the glass to resin ratio and frequency. Read Article What Is a Solder Bridge? Best Practices in PCB Design A PCB variant is often simply thought of as a new layout created from an old design. However, if you’re creative with your routing and layout, you can use a solder bridge jumper to configure portions of a single PCB layout for multiple variants. This lets you quickly create variants of a PCB layout without rerouting traces or changing your schematics. If you plan to use jumpers in your PCB layout, there are some important guidelines to follow to Read Article Pagination First page « First Previous page ‹‹ Page63 Current page64 Page65 Page66 Page67 Page68 Next page ›› Last page Last » Load More
