Symmetric Stripline Impedance Calculators and Formulas Symmetric Stripline Inductance or Impedance Calculators and Formulas In a previous article, we looked at the inconsistencies that can arise when using different calculators to compute the impedance of surface and embedded microstrip traces. Many of the same issues mentioned in the previous article apply to stripline impedance calculators. Symmetric striplines are easier to address than asymmetric striplines, both numerically and analytically. Here, we’ll give a short comparison of the various impedance formulas Read Article
Ethernet Layout and Routing Standards: MAC, PHY, and RJ-45 Connectors Ethernet Layout Routing Guidelines: MAC, PHY, and RJ-45 Connectors Magnetics termination has little to do with actual magnets. Here are some important ethernet layout routing guidelines (MII, RMII, RGMII, etc.) to ensure signal integrity. Read Article

PCB Librarians and SMART PCB Component Management PCB Librarians and SMART PCB Component Management In the 1972 classic movie “The Candidate”, Bill Mckay, played by Robert Redford, ran for the State Senate. Although he was a long shot and an underdog, McKay ends up surprising everyone with an incredibly close win. After the concession speech of his opponent, a vast mob surrounds McKay. He fights through the crowd, trying to reach his campaign Manager Marvin (played by Peter Boyles). Finally reaching him, he pulls him aside into a hotel room Read Article
How to Establish a PCB Library for Your Design Practice How to Establish a PCB Creator Library for Your Design Practice When we think of a library, we first think of a building which holds materials of some kind. In April of 1800, when the seat of the government moved from Philadelphia to Washington, one of President Monroe’s first acts was allocating $5,000 to purchase books for Congress to use. Once established, the Library of Congress originally held a total of 740 books and three maps. Now, it contains 32 million cataloged books and other print materials in Read Article
Parametric Information and PCB Data Management Parametric Information and PCB Data Management In the words of Tim O'Reilly, the founder of O'Reilly Media and a major proponent of Open Source & Software Development, “We're entering a new world in which data may be more important than software.” I tend to disagree with that; I believe that data is enhanced by software especially when we are talking about data related to PCB Management. I’m a long-time user of Altium software and very pleased with the way the software has evolved. So get Read Article
How Can You Make Sure PCB Design Data Is Both Accessible and Secure? How Can You Make Sure PCB Design Data Is Both Accessible and Secure? As a grandfather, one of the great joys of my life is to play with any of my five grandchildren. On top of their fun list is to play on the teeter-totter at the playground. They usually enjoy it until grandpa gets on one side and they try to lift me. Then the poor little tykes get a harsh lesson in leverage, balance, and just how heavy grandpa is. In PCB Design, it is all about balance. IPC-2221 reminds us that the design process comes with its Read Article
Operational Process Improvements and PCB Data Management Operational Process Improvements and PCB Data Management Is it practical or indulgent to look at exactly how the principles of good PCB Data Management can and should change our normal PCB Design processes? It is practical and necessary for operational processes to benefit from continual improvement. Let’s explore how to do so with PCB data management. Root Causes You need to allow specific PCB Data to change your operational processes so you can analyze and find the root causes of problems. However Read Article
Printed Circuit Assembly and Design for Cost Printed Circuit Assembly and Design for Cost The design process for an electronic system requires decisions that will influence the cost and performance of the printed circuit assembly (PCA). General Principles There is value in being able to quickly estimate the impact of design on cost. Because of the increasing pressure to shorten time to market, design engineers may not have the luxury of using trial and error and price quotes to fine-tune a new design. In addition, the further down the Read Article
