We have discovered a way to break a longstanding tradeoff in the design of a fundamental block used in phased arrays and signal processing systems! The humble, passive phase shifter featured in this article, published today in IEEE Transactions on Circuits and Systems I (Regular Papers), has achieved record-high resolution for a digitally controlled delay element (10 bits), while maintaining low insertion loss. Typically, higher resolution worsens loss due to resonances, finite Q, etc. We addressed this issue by moving beyond those resonances and working in a 'post-resonance regime' — a simple yet powerful idea! Please give it a read and share your thoughts! https://lnkd.in/eT7pUJwV

10 high-speed #PCBlayout design rules 1. Have a common ground plane right below the signal traces 2. Ensure adequate spacing between vias to avoid hotspots 3. Place vias symmetrically to eliminate impedance discontinuities 4. Maintain minimum bends while routing 5. Add serpentines to length match the traces 6. Maintain at least 3W spacing between the signal traces to minimize crosstalk 7. Implement daisy chain routing to avoid long stubs 8. Do not place components and vias between differential pairs 9. Design differential pairs with symmetrical paths and keep signals in parallel 10. Route differential signals on the same layer -- Read the article for more. -- Share this post with PCB designers and engineers. #ElectronicsDesign #SignalIntegrity #ElectricalEngineering

#Signalintegrity signifies the signal’s ability to propagate without distortion. It is the quality of the signal passing through a transmission line. When a signal propagates from a driver to a receiver, it doesn’t remain the same; whatever was originally sent will be received with varying degrees of distortion. This signal distortion happens due to factors like #impedance mismatch, reflections, transient oscillations, #crosstalk, ground bounce, and jitters in PCBs. Signal integrity issues are not a major concern at lower frequencies but are important when a PCB operates at a higher speed and frequency (> 50MHz). In the high-frequency regime, both digital and analog aspects of the signal need to be addressed.

This 1-minute design review from Mohamed Elbhoty could use some cleanup in the schematic and the DRC error list, but still a cool board. Also it's one of the few PCBs I have seen where cabling was added to the PCB layout as a 3D model, so you know it looks great in 3D!

💡 PCB design is full of rules of thumb—some built on DFM formulas, others passed down as industry “tribal knowledge.” In a fun chat, Andy Shaughnessy talks with experts Kris Moyer and Kelly Dack about when to trust these shortcuts, when to do the math, and how to find the right balance ⚖️. It’s all about smart, practical design: https://lnkd.in/g_BJQDbX

Can you save costs if you eliminate vias? Here's the question this engineer is asking: "I’m designing a simple two-layer PCB (35mm x 25mm) and can potentially complete the layout without any vias. I’m curious to know if eliminating vias from my PCB design can potentially provide some cost savings. Is it worth the effort to design the board without vias, or are the potential savings worth it?" Know the answer? https://lnkd.in/g9jwRy6h #pcbmanufacturing #pcbdesign #pcb #electronics

Pro tip: Always remember to add test points to your PCBA. They’re incredibly useful when it comes to debugging hardware, uploading firmware, and making sure everything works as it should. Here’s a challenge—can you spot the test points on this board? They might seem like a small detail, but they can save a lot of time when things get tricky. Let’s see who finds them first!

This RF MCU PCB comes from Krzysztof Strehlau, and I initially thought this was not an #esp32 but after checking again I think one of my remarks about the ground pin are wrong!

This 1-minute design review for a #usb drive comes from Amine Mehdi Mansouri. I often see ferrites on the VBUS line, and that VBUS line is sometimes powering a digital ASIC without an additional regulator to control the output. Just remember that correct functionality does not always equal EMC compliance! Want to have your design reviewed on the Altium® Academy youtube channel?

Flex circuits offer a significant mechanical advantage by eliminating points of interconnect. Each interconnect in a high-speed controlled impedance signal path is a potential source of signal reflection, which can degrade performance. https://hubs.li/Q02Lvpz80

Episode 155 of the Reliability Matters Podcast is now available. Ultra HDI Panel Discussion (recorded live at SMTAI). As the demand for smaller, faster, and more powerful devices grows, the need for innovative solutions in circuit design has never been greater. UHDI's represent a significant leap forward, allowing for more connections in a smaller space, pushing the boundaries of what's possible in electronic assemblies. But what exactly are UHDI's? Essentially, they refer to circuit boards with incredibly fine pitch interconnects, enabling higher functionality and complexity in much smaller form factors. This breakthrough is transforming industries like consumer electronics, aerospace, automotive, and medical devices, where space, weight, and performance are critical factors. In this episode, we’ll explore the advantages UHDI's bring to the table, from increased design flexibility and performance to better thermal management. We'll also discuss how UHDI's are set to impact the assembly process. With tighter tolerances and more intricate layouts, UHDI assemblies will require new approaches to assembly, inspection, and reliability testing. To better explain UHDI technology, we’ve put together a panel of subject matter experts. Tara Dunn, Director of Training and Education at the Surface Mount Technology Association (SMTA), will moderate a panel discussion with other subject matter experts. In addition to Tara, our other experts are Anaya Vardya CEO of American Standard Circuits, Chrys Shea from Shea Engineering Services, Michael Sivigny, owner and General Manager of CeTaQ Americas, and Oren Manor, Op-Center Core Program Business Director at Siemens Digital Industries Software. Ultra-HDI is here! And if you haven’t seen it on your assembly line yet, it’s coming, so stay tuned as we unpack the future of Ultra High Density Interconnects and what it means for the next generation of technology. #reliabilitymatters #uhdi https://lnkd.in/gZA3-RPw
