🔌 Transmission Line Models in PSCAD — Which One to Use? PSCAD offers 4 transmission line models. Picking the right one matters. PI-Section → Short lines, simple studies Bergeron → Most common. Covers TOV, protection, ferroresonance studies FD (Mode) → Frequency-varying behaviour on symmetrical lines FD (Phase) → Best accuracy. Cables, asymmetrical towers, wideband transients 💡 CIGRE recommends Bergeron as the minimum for most studies. Step up to FD Phase when precision matters. Full model comparison and CIGRE recommendations in the document below. 👇 Mohana Krishnan K Selvakumar S Priyadarshini Sridhar #learnwithmePSCAD #PSCAD #PowerSystems #TransmissionLine #ElectricalEngineering #EMTSimulation #PowerEngineering

Most PCB engineers control trace impedance carefully. Fewer think about what happens at the pad. That's where signal integrity problems quietly begin. In high-speed differential design, your trace impedance might be perfectly tuned — and then the signal hits a pad region. Suddenly: → Copper area expands → The pad sits directly over a solid ground plane → Parasitic capacitance spikes → Local impedance drops The result? Reflections, eye diagram degradation, and jitter you can't easily trace back to a root cause. The fix is a ground plane void beneath the pad — but the reasoning matters. This isn't about isolating ground. It's about compensating for a pad-induced impedance dip by reducing parasitic capacitance and restoring continuity along the signal path. But voiding introduces its own constraint: If you void L2 beneath a pad, the signal loses its nearest reference. So L3 must remain solid. Void both L2 and L3? L4 must hold the reference. Break the return path trying to fix the impedance, and you've made things worse. Return path continuity always comes before impedance tuning. When does pad voiding actually matter? Data rates above ~5 Gbps Large pad geometry relative to trace width Thin dielectrics Tight impedance tolerances For low-speed signals, the effect is usually negligible. Context determines necessity. And the clearance size must be simulated — not estimated. Too small → capacitance reduction is insufficient Too large → impedance overshoots Too aggressive → EMI risk and structural concerns Stack-up data + field solver. Not intuition. One more thing most discussions skip: DFM. Excessive or inconsistent anti-pad definitions fragment your reference planes, destabilize copper balance, and introduce impedance variation in production that your simulation never predicted. A layout that passes simulation but stresses fabrication tolerances won't survive volume production. Impedance control isn't just about trace width. Pad geometry and reference plane interaction are equally part of the equation. Good design is buildable design. What's your threshold for pad voiding in your stack-up — and are you simulating it or using rule-of-thumb clearances? #RayPCB #pcbmanufacturing #PCBDesign #SignalIntegrity #HighSpeedDesign #DifferentialPairs #ImpedanceControl #HardwareEngineering #EmbeddedSystems #Electronics #electronicengineering #pcbdesigner #pcbassembly

Does Solder Mask Affect High-Speed Signals? In one case we reviewed, a high-speed signal routed on the outer layer showed higher insertion loss than the same trace routed on an inner layer. Solder mask is usually seen as a protective layer for PCB traces. But in high-speed designs, it can also influence signal loss. One reason is the solder mask above outer-layer copper. Compared with inner layers, it introduces additional dielectric material and loss. For critical high-speed signals, this is one reason many designers prefer routing on inner layers with solid reference planes. Here is a summarized function of solder mask and its influence on PCB performance: 🔗 https://lnkd.in/dEasMGEn Curious to hear from other engineers: For high-speed signals, do you usually route on outer layers or inner layers? #PCBDesign #HighSpeedDesign #SignalIntegrity #PCBManufacturing #HardwareEngineering #DFM #KnownPCB

Does Routing Angle Really Matter?⚡🔍 In PCB design, small geometric decisions can introduce measurable electrical effects at the system level. Trace routing is not just about aesthetics — it directly affects impedance continuity, signal integrity, EMI/EMC behavior, and manufacturability. 🚀 In high-speed design, routing geometry is never trivial. #PCBDesign #SignalIntegrity #HighSpeedDesign #EMC #ElectronicsEngineering
