Let's take a look at back-drilling in PCB manufacturing 🧐 💡 It's a clever technique that removes leftover copper in vias—called stubs—that can distort signals in high-speed designs. By carefully drilling just deep enough (without hitting the active layers), engineers create cleaner pathways for data to travel. The result? 📝 Sharper signals, fewer reflections, and more reliable performance to meet today's technology demands. Sometimes even used in place of certain HDI attributes. #PCBdesign #BackDrilling #SignalIntegrity #HDI #NCAB #NCABgroup

BMT Partners With ATLAS ELEKTRONIK UK to Advance Autonomous Navigation Read The Full Article:- https://lnkd.in/eiV9rQ4q “BMT’s partnership with ATLAS ELEKTRONIK UK underscores the importance of simulation-based assurance in developing safe, reliable autonomous systems,” said Will Alexander, Campaign Lead for Maritime Autonomous Systems at BMT ATLAS ELEKTRONIK UK’s Principal Software Engineer for Command, Control, and Autonomy Systems, Ian Renton, atlas reflected on the collaboration: “In my view, this type of exercise is an invaluable addition to our existing test procedures." Steve Perry from the UK Ministry of Defence (MOD) Naval Authority and Technology Group (NATG) – Propulsion, Manoeuvring & Navigation Systems, then concluded: “Establishing the MASS SEAS assurance methodology has enabled the Naval Authority (NA), as the safety certifying body for MOD shipping, to delegate the assessment of the COLREG capability of innovate new platforms using cutting edge technology to a Recognised Organisation."

7 best practices for designing #RF vias 1️⃣ Design the via to maintain low return loss at the input, especially when dealing with wide bandwidths extending into the GHz range. 2️⃣ Ensure the presence of vias does not negatively impact the insertion loss. While insertion loss is not usually the focal point for vias, it is still a critical factor. 3️⃣ Maintain a minimum spacing of  λ/10 between the ground vias. For instance, at 2.4 GHz, the clearance should be 6 mm. 4️⃣ Place ground-connected vias near the PCB edges to reduce RF losses through the laminate. The EMFs are less confined near the edges. However, avoid placing them too close to the edge to prevent mechanical issues. 5️⃣ For mmWave PCBs, implement a via fence around grounded coplanar waveguides to enhance high-frequency isolation. This technique also suppresses frequencies below a cut-off and prevents mmWave interference with other signals. 6️⃣ Avoid return or stitching vias for slow-speed signals with rise times higher than 20 ns (e.g., GPIOs, I2C, and control signals) because such signals are less sensitive to impedance discontinuities. 7️⃣ Prioritize transition methods and the implementation of return paths (e.g., stitching vias) for higher-frequency signals or those with fast rise times to minimize radiation or crosstalk. 👇Check the link in the comments for more details. --> Repost for better reach. #rfengineers #radiofrequencydesigners #hardwareengieers #electricalengineering

💡 Even when using Ada or SPARK, debugging is still important for embedded systems, especially when you are working on logic close to the hardware. In this demo, Mark Hermeling shows how to add Lauterbach GmbH Trace32 to an Ada project in VS Code desktop, using Alire to build on the desktop and in a GitLab CI/CD pipeline.

🔊 Navigating Reverberation Chamber (RVC) testing methods and automation with ROHDE & SCHWARZ ELEKTRA 🔊 The R&S®ELEKTRA test software is a valuable solution for automating RVC test methods to streamline testing processes, delivering unparalleled efficiency and accuracy. As Reiner Goetz, Product Manager at Rohde & Schwarz, explains, “The complexity of immunity testing has shifted to software when using a reverberation chamber, and R&S®ELEKTRA is a great tool to automate your testing and make your measurements faster and more reliable. Rohde & Schwarz also provides fully compliant EMI test receivers, broadband amplifiers, signal generators, antennas, and other essential system components for immunity and emission testing in reverb chambers.” For closed-loop power control (Annex G of ISO 11451-5): R&S®ELEKTRA provides a specialized interface to seamlessly support field probes, enabling faster evaluation of statistical field strength in the RVC. Key measurement parameters such as cumulative distribution function threshold levels can be configured. The precise control improves measurement efficiency, and comprehensive E-field statistics are included in reporting. Bas de Groot, Owner of Comtest Engineering, shares on RVC chamber design, "A reverb room is equipped with an integrated mode stirrer system that turns stepwise or continuously during testing. The benefits of reverb chambers include high repeatability, the ability to test heavy and large EUTs, and a better representation of real-life environments. Applying fast stirring enables you to significantly reduce the time required for conducting an immunity test on your product by up to a quarter. The latest designs of the Comtest stirrer systems are perfect for fast stirring and are compliant with expected future requirements to test emissions of multimedia equipment according to CISPR 32 and full vehicles.” As real-world electromagnetic environments evolve due to the rise of highly integrated electronic products and numerous interference sources, traditional two-dimensional testing methods fall short in addressing these complex scenarios. This shift highlights the growing demand for RVCs that can effectively simulate these intricate electromagnetic environments and tackle EMC testing challenges. R&S®ELEKTRA emerges as a valuable and ideal tool for testing within RVCs, providing the automation and precision needed to navigate these complexities effectively.

Lauterbach TRACE32® development tools now support PX5 RTOS! We are pleased to announce that Lauterbach TRACE32 development tools now support PX5 RTOS. This TRACE32 tool support includes access to the PX5 RTOS internal structures and data, enabling developers to gain a deeper understanding of how their applications behave and utilize chip resources for faster and easier development. The TRACE32 PowerView software provides not only a static display of the current status of PX5 OS objects, but also the dynamic behavior of the OS objects over time, (e.g., an OS task scheduling analysis as well as many sophisticated real-time analysis functions, including symbolic function call trace and detailed performance analysis functions.) This latest integration helps PX5 RTOS developers accelerate their time-to-market, reduce overall costs, and deliver the best-quality products.
