DRCs in PCB Design: How They Can Save Your Design from Sinking For many years I owned a small boat which gave me hours of fun on the water, but there are a few critical rules that have to be obeyed. One of those rules is that you MUST install the drain plug before putting your boat in the water. It’s a lot cheaper to go for a swim intentionally, rather than unexpectedly in order to retrieve your new boat. Everyone knows that rules are there for our protection. But sometimes, whether accidentally or on Read Article Considerations for Designing a High Voltage PCB I used to think that high voltage applications were only used in power engineering. Since I had no desire to work at a power plant or transformer station, I was safe from having to learn high voltage PCB design considerations. Alas, my interest in space applications proved me wrong and forced me to confront my laziness. It turns out high voltage applications show up in almost every industry, from manufacturing and power plants to medical and Read Article Assessing the Post-Development Hardships of Uncontrolled Data Management For every, team, and business, getting to the release state should be the moment where you can breathe a sigh of relief. This moment, unfortunately, doesn’t always lend itself to joyful celebration. Project completion can mean a) you and your team have successfully constructed a design without any flaws in the documentation process and can now prep for its release, or b) you’ve successfully completed your design but realize a minor (or major) Read Article IoT Resource Bundle From the early days of printed circuit boards, the electronics industry has made huge strides in board materials, copper printing methods, miniaturization, rigid-flex, ELIC, EDA, and much more. Many of the devices we use in our homes, our vehicles, and in our workplaces would not be possible without this continuous evolution of PCB design and technology. The scope of creativity from individuals is unbounded. While the infrastructure for IoT can Read Article RF Technologies for Low-Power Wireless Communications: Ambient Backscatter I love family reunions, though, with forty people in my extended family they can get a bit hectic. Whether we’re playing cards, swimming, or at the dinner table there’s always someone telling jokes and stories. In fact, most people are trying to talk so sometimes you have to yell to be heard. It can also be difficult to communicate in the electromagnetic spectrum. Your devices often have to “shout” their own signals into the void in order to Read Article PCB Editor View Modes PCB editor view modes allow designers to locate and correct errors in particular areas of the board. Altium Designer features multiple ways to view your design, allowing you to be most efficient and to help avoid errors. These different PCB editor view modes have allowed users to find and fix design problems, such as why a flex board does not fold, why components are on the wrong layers, and why dead copper is not being shown anywhere on the board Read Article How to Prevent Hairline Short Circuits in Your PCB Circuit Design What’s worse than finding a strand of hair in your pasta when you’re out on a dinner date? Finding it after it has ended up in your mouth. There are two ways to avoid awkward scenarios like this. For one, you can keep a close eye on your food and make sure it is hair free before it enters your mouth. The second is to ensure that there is no chance of a hair ending up in your food; in this case, you might need to go to a new restaurant. In PCB Read Article High Voltage PCB Design: Creepage and Clearance Distances for High Voltage Designing high voltage PCBs following specific spacing guidelines is critical. In high density circuit boards, spacing is even trickier and more important for protection. Read Article IoT Hardware Boards and Platforms Are Becoming Flexible Do you remember all the fads and obsessions you had when you were a kid? When I was younger everyone was going crazy for Pokemon and whatever electronic gadgets they could get their hands on. These two crazes eventually combined into one ultimate trend, the Tamagotchi. It was a huge hit, building on the portable electronic fever and children’s love of tiny unrealistic animals. Recently two fads in the PCB world have combined, flexible electronics Read Article Capturing Key Design Details in PCB Documentation One of the most important yet often avoided aspects of documenting a design is the formal design document. Too often we finish the design, generate fabrication, assembly, and validation documents then consider the job done. Properly capturing the system specification, design intent, design process and traceability back to the specification is a time-consuming and arduous yet very necessary task. The design document must capture all aspects of the Read Article USB Type-C: A New Frontier for Power and Data Transmission When it comes to PCB design, imbalanced power demands in your board can knock the wind right out of your sails. Power discrepancies can quickly turn the tide of your design process and can be extremely difficult to amend without having to do considerable rework. So what’s the solution for getting your voltage levels just right, and is it possible to increase the transmission of data while reducing your power consumption? To start, you’d need a Read Article Structural Integrity and the Challenges of Rigid-Flex PCB Design With the advent of rigid-flex, we’ve been able to fit more in a smaller form factor than ever before. Not only that but rigid-flex designs have an edge over rigid designs in weight and reliability. I could write a blog on just the advantages of rigid-flex, but I’ll leave that for another day. Rigid-flex is great, but there are some things you need to be aware of when you work with it. What I’d like to highlight in this blog are the routing Read Article Designing General PCB Controller for your Circuit Board Layout I always thought that to be successful you need to emulate the success of others. When I started my career, there weren’t any single board computers like Raspberry Pi, and no one took Arduino seriously for industrial applications. You can imagine how bad it was the first time I did maintenance on a general purpose controller that I designed. It was a fire alarm controller that had over 50 wires manually screwed onto it. I had to replace a faulty Read Article PCB Circuit Products: Should You Design for Repairing? As an engineer, I always feel like it’s a personal failing when I have to call someone else in to fix my stuff. Whether it’s electronics or the occasional bit of haphazard woodwork, I can’t ask for help until I’ve tried to sort it out. Plumbing, however, is another story. Then I call for help immediately. The problem with the impulse to fix your own stuff is that a lot of companies don’t actually want you to. I can’t count the number of times Read Article Semiconductor Fiber Could Replace Fiber Optic Cable Transmission Lines The Internet is a strange and wonderful place. I grew up at the end of the age of dial up Internet when chat rooms were all the rage. Now I occasionally enjoy using the Internet to play some online games, which was impossible back then. My telephone router and its copper network could barely support enough bandwidth to load an image. Now our networks have been upgraded with blazing fast fiber optics. While these communication systems are Read Article Spin Wave Breakthrough Could Lead To Ultra Low Power Non Volatile Memory At my university, we weren’t required to take quantum mechanics. The whole premise behind it is that you can never truly “know” anything, just the probability of something right? It sounded a bit silly to me. Then I got into high-level electromagnetics and signal processing and had to deal with a lot more numbers that didn’t make sense. I’m glad some people decided to take that course because they are the ones making breakthroughs in quantum Read Article How Google Glass Technology Works and What Makes It Tick Arthur C. Clarke once said, “Any sufficiently advanced technology is indistinguishable from magic.” If that’s the case then Google must employ a lot of witches and warlocks. They’ve been pushing the tech envelope for years and many of their ideas are now coming to fruition. Products like their self-driving cars are almost here, and I’m personally hopeful about a smart sensor platform that Google helped fund. By far the coolest take we’ve been Read Article Pagination First page « First Previous page ‹‹ Page173 Current page174 Page175 Page176 Page177 Page178 Next page ›› Last page Last » Load More
