Techniques to measure and avoid jitter in #PCBs ?? A signal's deflection from its ideal rising and falling edges is called jitter in PCBs. Jitter in clock signals can impact the timing synchronization and consequently disrupt the overall signal integrity of a system. ?? Clock signals with less jitter are essential to meet high-speed data communication. ?? Non-uniform impedance, crosstalk, interference, and power supply noise are some prevalent factors that reduce the signal-to-noise ratio (SNR) and cause jitter in communication channels. Clock jitter in your designs can be detected using an eye diagram. In this article, you will learn: ??Sources of jitter in your PCBs. ??How to measure clock jitter using an eye diagram. ??Design techniques to eliminate jitter in circuit boards. ??Various types and sources of jitter in PCBs. ??Read the article: https://lnkd.in/gf-ii4pA #pcbdesigners #hardwareengineering #electricalengineering

Humanoid #robotics PCB design and advanced manufacturing techniques ??Humanoid robotics circuit boards enable communication between sensors, actuators, and AI processors, a critical factor in building advanced robots. As robotics technology evolves, high-density, flexible, and thermally efficient boards play a key role. ??When designing printed boards for humanoids: ??Select high-frequency flexible materials like DuPont Pyralux TK and Panasonic FELIOS R-F775. ??Use flexible printed circuits (FPC) to integrate cameras, sensors, and AI processors for facial recognition, environmental awareness, and real-time decision-making. ??Incorporate rigid-flex PCBs to provide structural support and flexibility, aiding in smooth motion, balance, and terrain adaptation. ??Integrate microcontrollers/microprocessors in the main circuit board to process sensor data, run AI algorithms, and control actuators in real-time. ??Read the article to learn more: https://lnkd.in/gh7jwvuf -- > Repost for better reach. #humanoidrobotics #hardwareengineering #electricalengineering

Non-PTFE vs. PTFE vs. ceramic-PTFE PCB materials ?? Selecting the right material, whether PTFE or non-PTFE, is crucial for your RF designs. This choice significantly affects signal loss, dimensional stability, and board reliability. It's not just a simple decision; it depends on the specific needs of your applications. ?? PTFE? and ceramic-filled PTFE laminates offer superior electrical performance and are preferred for radio-frequency applications. ?? On the other hand, non-PTFE materials strike a balance between high-speed signal transmission and hassle-free fabrication. ??

5 important #DFM checks for PCB designers A successful #PCB starts with a well-designed stack-up—get it right before diving into layout. Once your stack-up and component placements are in place, routing comes next. Even if you haven’t finalized all the rules, it’s key to separate critical and non-critical elements early on. Drill setup is just as important, especially when designing for specific industries like medical, aerospace, or military. Always ensure your #PCBmanufacturer approves your drill specs to avoid fab roadblocks. Finally, details matter—proper solder mask application, silkscreen clarity, and well-formatted design files make all the difference in ensuring a seamless transition from #PCBdesign to fabrication. Plan ahead, and set your board up for success! Watch the full webinar: https://lnkd.in/gN_VR9tz

Imagine if your?#RF PCB design achieved seamless signal transmission, minimized power loss, and eliminated impedance mismatches—right from the start. Integrating #antennas into PCBs requires?precise tuning of materials, impedance, and layout. One wrong move can lead to poor reception, high insertion loss, and excessive #EMI. Join Vandana C. C. to learn how to optimize antenna selection, impedance matching, and #PCB layout to ensure maximum performance. What you’ll learn: ? How to choose the right antenna for your application ? Key material properties for RF PCB laminates ? Strategies for #impedance matching and reducing signal reflections ? Best practices for antenna placement and grounding ? #DFM rules to ensure manufacturability and reliability

What is kitting in #PCBassembly? ?? Kitting is the process of putting together a set of components as a kit required to assemble circuit boards. Here, the customer provides all the components that go on the board. ?? Kitting brings all the materials/parts into one single package. It is extremely beneficial for the commencement of assembly since all the required components are available, verified, and placed in appropriate packaging. ?? Every board design and quantity requirements vary according to the customer. Hence, the kit criteria for each assembly project are different. In spite of these, there are particular rules to consider and standards to follow. ?? The analogy could be that of cooking a recipe when all the ingredients are collected either from the market or from the kitchen and pantry. All these ingredients are brought together on the kitchen table and then cooked. ??

6 common challenges in designing an #HDIPCB ?? The increased component density and multiple signal layers result in complex routing requirements within a limited space. This leads to routing congestion and increases the risk of crosstalk. ?? Traces of varying lengths due to a compact layout can lead to propagation delays and skew between signals. ?? Impedance mismatch in HDI due to insufficient trace widths and spacing causes signal reflections and signal degradation. ?? The compact layout can make it challenging to ensure low-impedance power distribution and effective decoupling, leading to voltage fluctuations. ?? For HDI designs operating at high frequencies, electromagnetic phenomena such as skin effects and dielectric losses become significant, leading to signal attenuation and distortion. ?? Miniaturized components, densely packed traces, high-speed signal switching, and component power dissipation can lead to localized heating, damaging ICs. ??Read the full blog to learn more: https://lnkd.in/g7vfSMah --> Reost for better reach. #highdensitypcb #pcbdesign #hardwareengineering #electricalengineering
