Intro to High-Speed Design TOPICS IN THIS SOLUTION Complicated PCB Design for High-Speed Applications High-Speed Constraints Are Used in Every Phase of the Design Process Analyzing the Design for Consistent Operation that Meets Specification You’re creating products that are made for the present day, which means moving past traditional PCB technology and design techniques. It takes more than innovation to perform these tasks well - how do you create high-speed interfaces Read Article What is PCB Data Management? Successful design and manufacture of any PCB requires managing data. Every PCB project includes a ton of data on the components, front-end schematics, the physical layout, and manufacturing files. There is other documentation that may be needed that is not captured in your PCB design software. This all has to be tracked and managed by the designer because working with incomplete or out-of-date data will result in a design that doesn't perform as Read Article PDS Design For Ultra-low Power Implementations When it comes to low power implementations, products are characterized as very rarely having high current options, being small in size, being optimized for power management and having the necessity for batteries to last as long as possible. There’s a broad spectrum of products that fall under these criteria including, but not limited to, smartphones, smartwatches, remote monitoring devices and medical devices to name a few. In terms of PDS design Read Article Power Play—Successfully Designing Power Delivery Systems Across the industry, the design element that continues to cause the most problems is the power delivery system (PDS). And, as a consulting firm, for the last several years the majority of problems that we have been called in to solve have always centered on PDS problems. As noted in my previous blog on guard traces and their ineffectiveness, every time we have been called upon to solve an EMI problem, we have always ended up fixing the PDS. This Read Article Meshing Design with Electronics Assembly and Flux Cleaning PCBAs require flux cleaning during assembly, as well as other cleaning steps to remove other soils. Read this blog by expert Barbara Kanegsberg to learn more about cleaning processes. Read Article The Art of Selecting Connectors Connectors are the unsung stars of both a product and its hardware development. Any Apple user knows the romantic tale the company has spun from infatuation with the first magnetic power connector through the betrayal of the 3.5mm jack to today’s ‘it’s complicated’ status thanks to the baggage their dongles create in pursuit of beauty. Product developers have similar emotional experiences with their prototypes. An unreliable connector that has Read Article Embedded Software Is Everywhere: Potential Implications The amount of smart, connected products is increasing faster than ever. It was only very recently that IoT technology jumped from our phones and computers to our refrigerators, our lighting systems, and our vacuum cleaners. It's starting to seem like nothing is excluded from this extensive digital overhaul. In 2016, the smart home market was worth about $24 billion. By 2022, it's expected to reach $53 billion. Smart homes and robots are no longer Read Article Weekly Digest: Documentation, Datasheets and Reliability In this article, we’re rounding up and collecting everything we’ve published this week for your weekend reading. Articles from PCB Design Experts For people who like to read there’s never a shortage of informative articles on the PCB Design Blog .

How to 'GIT' Collaborative with Altium - by Ari Mahpour PCIe BGA Fanouts and Escape Routing - by Zach Read Article DFSI: Stripline Differential Impedance Calculation Made Easy As a PCB designer, you may hear your signal integrity overlords dictate controlled impedance with a specific value and tolerance. As someone who has requested these things, I know designers have trouble with implementing this in their trace geometry. This article details what impedance is, how it is calculated, and a practical way for PCB designers to determine the proper geometry for their application. When designing high-speed serial circuits Read Article Why PCB Prototyping in the U.S. is a Crucial Element For Success Within today’s global design and manufacturing environment, moving PCB manufacturing offshore is our industry’s de facto product development process. Many believe that PCB prototyping could and should be moved offshore to take advantage of the rising skill and capability levels of the offshore resources in Taiwan, China and Korea. This has led to a crisis in the U.S. PCB prototyping industry. U.S.-based companies find it difficult to stay in Read Article How to "Git" Collaborative with Altium Designer Getting collaboration right with any ECAD tool can be rather challenging. For most of us we tend to stick with the “old school” methods: Work on your design Send a zip package via email to another Other works on the design and sends a zip package back to you for review You work on your design and send back to the other Repeat forever This method not only clutters up your inbox but it also forces you to work in a serial fashion. The solution to Read Article Datasheet Reliability with Ben Jordan In this OnTrack episode Judy Warner and Ben Jordan discuss about Datasheet Reliability. Can you trust them? And what does “Gilded” mean? This & more about verifying app notes. Watch the full episode. Read Article PCIe Card Guides: BGA Fanouts and Escape Routing With all the chips that appear on a PCI or PCIe card, laying out and routing these boards might seem extremely complicated. However, the standardized architecture of PCIe provides considerable flexibility for designers. One issue that is a bit complicated is PCIe BGA fanouts for components on these cards. The trick to implementing a fanout and escape routing strategy is ensuring that you comply with the PCIe layout and routing specifications Read Article Series Termination Resistor Calculation With transmission lines, some things never seem to be simple. Determining the termination technique and the values of components in a termination network shouldn’t be a difficult task. Most PCB design programs force you to look online for calculators, or you’ll have to run the calculations by hand. Instead, your design software should make it easy to test a range of component values in your termination network. Some components, traces Read Article Standard PCB Thickness and Your Layer Stack I’ll confess that I love 1990’s sitcoms. If Jerry Seinfeld were a PCB designer, he would probably ask “what’s the deal with the 1.57 mm board thickness?” It’s a fair question after all, and it makes you wonder why some standard values (e.g., 50 Ohms impedance in RF systems ) are used in PCB design and other areas of engineering. There are good reasons why these and other design values have become in standardized in PCB design, even if they aren't Read Article The Essential Tools You Need for PCB Design Whether you’re building a house or building a PCB, you need the right tools in your toolbox. Every designer needs to have CAD tools for component placement, but even command line-based CAD software can be used for accurate component placement. With modern electronic devices becoming more complex at all levels, designers need tools that help expedite essential design tasks. Choosing the right set of PCB design tools requires weighing a number of Read Article LVDS PCB Layout Guidelines for Ensuring Signal Integrity When you first get started in high-speed PCB design, you'll spend a lot of time encountering and understanding an alphabet soup of acronyms. MIPI, USB, PCIe interface, SATA PCB layout... the list of acronyms used to name high-speed digital interfaces is long. Low-voltage differential signaling (LVDS) is an older interface that was standardized for differential data transfer at high speeds, but it remains in use today for a variety of imaging and Read Article Pagination First page « First Previous page ‹‹ Page100 Current page101 Page102 Page103 Page104 Page105 Next page ›› Last page Last » Load More
