PDS Design For Ultra-low Power Implementations 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 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 Assembly 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 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
Implications of Embedded Software Everywhere 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

DFSI: Stripline Differential Impedance Calculation Made Easy 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 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 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
