    Prioritize Precision Querying in Circuit Board Design Software There is nothing worse than losing your car keys when running late to an important meeting. Car keys are small and remembering where you put them becomes impossible given the projects taken on in the interim. They could be anywhere. These days it is possible to use RF devices to locate your keys. Having user-friendly technology keeps stress levels low. Working with a complex circuit design within EDA tools can pose the same problem. With Read Article
    USB Charger Project in Altium Designer: Part 1 When I’m in my office, I keep my pluggable USB charger around, otherwise the battery on my phone is likely to run out. If you want to build your own USB charger, you can create your own USB charger board with the powerful schematic design and layout tools in Altium Designer. Here, I’ll present the overall design process for a portable USB charger. The charger requires 12 V of power and charges two external devices through two USB ports. We’ll Read Article
    More than a Right-Click Menu Multi-Channel PCB Design When it comes to creating a schematic I want the tools to work for me and not the other way around. I want easy access to, I want to place and connect those, and I want to be able to do all of this without having to jump through a lot of hoops to get there. Sadly many PCB design CAD systems don’t seem to share my opinion. I’m looking for an easy right-click menu solution while most CAD systems appear to want me to memorize a of ancient texts and Read Article
    Showcase Your Designs and Win Featuring San Diego PCB Design Would you like a chance to showcase the cool electronics you’re creating? Altium is giving engineers, students, makers, and hobbyists like you the opportunity to have their electronics featured on the Altium Stories YouTube channel! Contest Rules Video must be between 3-7 minutes in length Videos must include the following: Introductions and information about your engineering/designer/creator background Projects you Read Article
    Methods For Calculating And Measuring Impedance, Part 1 In a previous article, I talked about the various transmission line properties that affect impedance. In this two-part article, I will address the methods used for calculating impedance. Included at the end of Part 1 is a list of 2D field solvers along with brief descriptions of their capabilities. Part 2 of this article will address other design aspects that influence impedance, including the frequency at which impedance should be measured Read Article
    Requirements Management and Quality Functional Deployment “Ending up in the wrong place is the result of bad directions, not bad driving. Product failure in the marketplace results from errors in requirements, not implementation.” - Thomas L. Musto, Chairman, IBM Corporation (Retired) A definition of QFD: Quality-Functional-Deployment (QFD) [literal translation of the Japanese characters] is an analytical method to help you transform customer needs (the voice of the customer [VOC]) into engineering Read Article
    Relative Permittivity of PCB Substrates: High-k or low-k dielectrics? The relative permittivity of water makes this pencil appear bent If you’ve paid attention to refraction, then you know something about the physics of relative permittivity. The semiconductor industry has managed to continue scaling to smaller technology nodes by using materials with high dielectric constant (so-called high-k dielectrics), but can you see similar benefits in your PCB with similar substrate materials? What about the use of low-k Read Article
    How to Create a PCB Manufacturing Cost Estimation Unless I receive a layout job directly from a manufacturer, my clients will usually ask if I’m a manufacturer. My company doesn’t manufacture boards, but I think it’s important to keep clients informed of the manufacturing costs for new PCBs. Once I started gathering estimates for some of my first projects, I started to better understand the primary cost drivers of PCB manufacturing and how to properly structure a comprehensive estimate for my Read Article
    What is Burn-in Testing for Electronics? Once you’re planning for production of any new board, you’ll likely be planning a battery of tests for your new product. These tests often focus on functionality and, for high speed/high frequency boards, signal/power integrity. However, you may intend for your product to operate for an extreme period of time, and you’ll need some data to reliably place a lower limit on your product’s lifetime. In addition to in-circuit tests, functional tests Read Article
    PCB Via Current-Carrying Capacity: How Hot is Too Hot? One common question from designers, particularly new designers that are learning about industry standards, is regarding the current-carrying capacity of conductors in a PCB. Trace and via current-carrying capacity are legitimate design points to focus on when designing a new board that will carry high current. The goal is to keep conductor temperatures below some appropriate limit, which then helps keep components on the board cool. While the Read Article
