[PSES] SV: [PSES] Stripline - discontinuity in adjacent ground planes

Note that the worst situation may occur when both planes are equal, In this PCB, they are more or less equal. It's an 8-layer stack (bottom/ Layer8=GND, Layer7=Signals, Layer6=GND, and .). But the signal traces in Layer7 have now continuous return path in both L8 and L6. Regards Amund

When going for a RED certificate from a Notified Body, have you received a risk assessment template to fill in or do you supply with your own self-made risk document? (Maybe based on CENELEC guide 32 . ) Best regards Amund

Hi Ken No, I have not considered edge-plating. I’ll look into this now. We have some high frequency noise (400-500MHz) from differential lines leaking out from an inner layer of a multilayer pcb. Edge-plating might be a good solution. Thanks for the tip. BR Amund Fra: IBM Ken
