Trip to the Weizmann Institute of Science in Israel My name is Piotr Lazarek and I’m a second-grade student of the secondary school “Filomata” in Gliwice. My passion for physics, informatics and new technologies has resulted in an innovative project; an autonomous vehicle which measures concentration of different elements inside soil. I dedicated two years of my hard work to designing and creating a prototype of the device. I’ve already posted an article about my work, so if you’re interested in Read Article How Do the Seamless Transfer and Use of PCB Design Data Improve Workflows? Introduction One of the more thrilling events in track and field is the 400 Meter relay race. Understand, I don’t run; rather I enjoy watching. However, the most critical part of every race is the transferring of the baton to the next runner. I was watching a race some time back where one team was way ahead of the others and was coming around the final turn for the last hand-off. But, THEY DROPPED THE BATON, and they ended up losing. How Read Article PCB Design - It is a Team Sport Introduction A poem by John Donne is the source of a phrase we are all familiar with: “No man is an island.” Although he was speaking of how human beings do rather poorly when isolated from others and need to be part of a community to thrive, this principle is especially true when it comes to the PCB Design process. That no single person—or better said, roles—are involved in the PCB design. I would contend that for any PCB Design to be a success Read Article Solving Component Library Errors During PCB Layout Reuse With the right PCB design package, you can even reuse layouts for these old cell phones I recently bought a new computer after data on my old hard drive started to “magically” become corrupted. Once I broke into my new computer and transferred my data over, I became worried I wouldn’t be able to reuse my old data. When it comes to simpler things like text files or images, you’ll have no problems; you can immediately reopen and reuse these files Read Article 77 GHz Radar for Automotive Radar PCBs: Routing and Signal Integrity Technology moves quickly these days, and automotive radar has transferred from primarily operating near a 24 GHz to a 77 GHz wavelength shortly after its introduction into new vehicles for object detection. Recent regulation changes have allowed the transition to 77 GHz, which provides a number of benefits. Shorter wavelengths facilitate wider bandwidths, and provide better resolution, smaller device form factors, and longer range. This band just Read Article Automotive Telematics Systems Design In 2015, the cost of the electronics in a new car surpassed the cost of raw steel for the first time in history. We shouldn’t be surprised; the increasing number of electronic systems placed in cars over time made this change in cost structure inevitable. As cars become more autonomous, more connected, and include more creature comforts, this trend is only going to continue. After the OnStar system was popularized by General Motors in the 1990s 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 Advanced Electronics: Understanding Design Challenges for Space Applications Part 1 Electronics design for space applications is a subject I’ve always been passionate about, and understanding the reasons particles can damage circuitry has always fascinated me. In this article, we’ll discuss how a Beta or Gamma particle can create—for a short period of time (usually referred as SEE or Single Event Effect)—a large current in your design which could lead to permanent damage if ignored. We’ll discuss a technique I have used in my Read Article Mike Buetow on PCB West Free Expo pass and more. Mike Buetow shares details about the upcoming PCB West in Santa Clara on September 9 to 12. Watch this OnTrack Episode for complete event details. Read Article How Does Altium Designer Improve PCB Design Workflows? One of the great pleasures in my life is to be the grandfather of—as of now—five grandkids. It’s interesting to watch them go through various stages of learning. There is Caleb, who is four, and Ashley, who is five (though she loves to remind everyone that she is NOT five, but five and seven months). Both are in different stages of learning. Ashley’s question for everything is “WHAT”, and Caleb, his question is “WHY.” What are we doing? Why is Read Article Major League Hacking Fuels Passion for Engineering Students Judy Warner : Jon, please share briefly about your background and what inspired you to co-found Major League Hacking. Jonathan Gottfried : I grew up tinkering with technology, but when I went to college to study Computer Science it was so much more academic than the creative building that I loved to do. I switched majors to history, started doing programming work as a consultant on the side, and ended up graduating and becoming a Developer Read Article Electronics Lab Equipment: Kitting out a Lab from Scratch Setting up a new electronic lab from scratch? In this article you'll learn essential information from budget, tools, your first soldering station, prototyping equipment, and more. Read Article Engineering Laptop Buying Guide Mid 2019 Previously, I covered buying a desktop computer for engineering purposes in The Definitive Engineering Computer Buying Guide Mid 2019 . I only touched on engineering laptop/notebook computers at that point, if you’re looking at buying an engineering laptop this is the guide for you. If you’re looking for a laptop specifically for engineering work, my expectation is that you are traveling a lot or are a student. Either way, you’re not looking for Read Article The Definitive Engineering Computer Buying Guide Mid 2019 If you’re looking for a new PC for engineering (electronic or otherwise), you don’t need to break the bank. This guide is for those of you more focused on engineering than keeping up with the latest PC hardware. Laptop vs Desktop Unless you plan on moving around a lot, or just don’t have a place to put a desktop computer, buying or building a desktop computer instead of a laptop will save you a lot of money and give you significantly better Read Article Selecting the Best Flex Fabricator What are the key things to consider when selecting a fabricator for flex and rigid flex? When a designer is embarking on their first flex or rigid flex layout the challenge of learning a new material set and new design rules is often compounded by the added challenge of researching and selecting a new fabricator who has the capability to manufacture flexible materials. It really isn’t surprising, there are many fabricators that work with both Read Article The Impact of Stackup Design on Signal Integrity As noted in several of my blogs as well as those of others, signal integrity is one of those elements within a high speed PCB design that has to be factored in from the start of the design concept. From its inception, signal integrity is carried through from design to board fabrication and final assembly. But, there are aspects where signal integrity is not always at the forefront of the design process, including the creation of the PCB stackup Read Article Validation Structures for Signal Integrity Let’s say you’ve just received a populated switch or GPU PCB from your favorite PCB fabrication and assembly site. You sit down at your computer and start up your GUI or console to begin transmitting data. Trouble begins—the protocol to bring up the link isn’t working. What do you do? Checking the voltages and jumper positions is easy enough, but what about the signal integrity of your channel? Assuming that you did all of the required Read Article Pagination First page « First Previous page ‹‹ Page89 Current page90 Page91 Page92 Page93 Page94 Next page ›› Last page Last » Load More
