Journey Through Embedded Active Components in PCB Substrates with Pacemakers With 200,000 pacemakers implanted in the United States per year, the surgical process to correct heart abnormalities has become routine. When preparing for the process, cardiologists choose from three different incision types to determine the best implant method. Each type of incision impacts patient comfort and the amount of risk involved with the surgery. The incision provides access to a vein and allocates space for the pacemaker. A Read Article Now that They’re Assigned, Find and Report Testpoints in Your PCB Design Whether it is a test in school, a driver’s test, or some sort of casual mention of a test at work, the word “test” can cause normally calm people to have a sense of anxiety. On the other hand, once beyond the test you can see those same people visibly relax. Perhaps that is why when PCB designers finish assigning testpoints to their design it is easy for them to breathe a huge sigh of relief. But, once you’ve assigned those testpoints there’s Read Article Scaling, Not Sinking Your Electronics: BOM Management Advice The most stressful part of owning a boat was when it came time to launch or recover it from the river. The boat was large and together with the trailer and truck, there was a lot of equipment to maneuver up and down the ramp without making any mistakes. If some kind of problem came up I would end up with the boat, the truck, or me sinking into the water. That sense of anxiety was very similar to the feelings I’ve experienced working with Read Article 7 Benefits of In-House Fabrication and Additive Manufacturing If you are like 98% of the PCB designers out there, you know what it can be like to run through the gauntlet of outsourcing a design to a third-party manufacturer to receive a prototype or two. The process is usually a little painful, often pricier than you’d have hoped, and leaves you waiting for longer than you’d expect. I often think that the manufacturing process is similar to going out to dinner at an overrated restaurant; you’ll wait on an Read Article Connect and Conquer: Multiboard Design Adaptation in PCB Design Software Years ago I designed boards at a service bureau where there were several different customers and the boards that I worked on were unique in size and function. And in all of those designs, none of them were ever from the same system. Not only was it more to spread the design work around back then, but the only way to do system design was to create the boards individually and then test the prototypes together. With faster times to market and Read Article John Watson on Altium Enterprise Solutions Going Beyond PCB Design Curious what a professional PCB Designer thinks about Altium enterprise solutions and AltiumLive? Listen to the OnTrack Podcast to find out what John Watson thinks and how the new solutions can help your team. Read Article Minimize Propagation Delay in Logic Gates: Synchronize Pulse Trains When you have an analog watch, daylight savings time can wreak havoc in your personal and professional life. You might wake up and not even realize that you are an hour off schedule. No one wants to admit that they have fallen victim to daylight savings time, and your entire schedule has to resynchronize when this happens. Synchronizing your clock and your electronics components is critical in high-speed PCB design. Applications like bus trace Read Article Choose Unified Symbols for Your PCB Prototype Design Documents I love spending hours at the bench soldering parts together and looking at the resultant signals they produce. It is satisfying to see the signals take shape on the oscilloscope as I refine each block. I’m surrounded by tools and equipment, little bits of wire and solder strewed from the invention process. Joining the beautiful mess are scattered components pulled from sample parts binders stored in the lab. Soon my prototype design will be ready Read Article Customize designs with Consistent and Flexible Custom Rules and Queries In the early stages of a circuit design, I frequently consider mechanical dimensions along with circuit requirements. Knowing dimensions of large components helps me visualize where they will fit with respect to overall three-dimensional device enclosure and the board’s location within the space. During the thought experiment for fit, I begin making notes about tolerances I’ll push as a tradeoff between electrical functionality and mechanical Read Article Don’t Reinvent the Wheel: Use Altium Multi-Channel Design for Easy Repeat Circuit Use If you are like me, you would agree that one of the most wasteful exercises is repeating the same task over and over again. Of course, I am not referring to activities that require repetition in order to achieve a good level of competence. After all, practice does make perfect. Instead, I am speaking of the wasteful recreation of a completed PCB design to use in a different product, which is akin to reinventing the wheel when it is already in use Read Article OnTrack Newsletter May 2018 On Track Newsletter May 2018 VOL. 2 No 2 Welcome to the May edition of the Altium OnTrack Newsletter!

We have an expert point of view in this episode of OnTrack The PCB Design Podcast. Read Article 44 DraftsmanSeamlessPCBDrawingProcess_ - Features:ADSCvid Watch Video Incorporating DFM for Panelization in Your Electronics Oftentimes, in a larger production environment, companies seek small tips and tricks along the manufacturing route in the hopes of significant cost savings. As a ‘low hanging fruit’ of costs savings, manufacturing is (or at least should be) a highly discussed topic early on in the design phase. Keeping manufacturing principles and specifications in mind at the design stage is what is known as design for manufacturing (DFM). There are a handful of Read Article Hybrid or Compact: Fractal Antennas in PCB Design The Mandelbrot Set was always a popular poster among my fellow students when I was in college. The zoomed-out picture hung on dorm room walls and even appeared on some graphic t-shirts. The fact that no one seemed to know about the Mandelbrot Set or understand fractals didn’t seem to matter. It wasn’t until much later that I realized how useful fractals could be in designing antennas. There are many antennas in the PCB world including: microstrip Read Article Build High Density Interconnect PCBs with Skip Vias All high-density PCBs rely on specific via styles to make connections into the inner layers without taking up space for routing. This is always driven by the components used in the PCB, namely fine-pitch BGAs with many high pin counts. One of the options for routing into inner layers as part of fanout routing is to use skip vias. Type-I HDI stackups will include skip vias as part of their routing options in an attempt to avoid the use of buried Read Article Increase Your Component and Trace High Density With Via-in-pad Plated Over Technology I’ve got this awesome four-speaker stereo system with a subwoofer in my apartment that my neighbors love to hate. As much as I enjoy listening to music on this thing, the only part I hate is the mess of audio cords that hide behind the speakers. The last time I tried to clean behind my system, I nearly ripped out some of the audio cords. If only routing my high density of audio cords was as easy as routing traces on an HDI printed circuit board Read Article Pagination First page « First Previous page ‹‹ Page132 Current page133 Page134 Page135 Page136 Page137 Next page ›› Last page Last » Load More
