Just 2 hints of thousands:If you implement 2 ground planes make sure the ground references on top and bottom are related to the closest ground layer .
The stack will than be: Stop -- GND --Stop2 -- PWR - Misc - Sbott2 - GND -Sbott ((S=signal))
(basically you route 2 x 3 layer boards critically, and bond them together with a power plane in between.)
The signal should not cross the board and be tempted to flow on an opposite ground layer, but
will remain always close to the corresponding ground layer.Make sure both ground layers are extremely well coupled together, esp on board edges
If you implement SMPS locally give it a local top layer ground area to connect the principal
switch elements together. Connect by a dice pattern 5 via to main GND Good luck. Gert Gremmen On 10-2-2020 8:27, Amund Westin wrote: contact to the nearest ground layer,
I’m looking for articles about how to do good EMC layout on multilayer PCB.Choice of PCB layer stacking (8 or 10 layers) and basic routing techniques are the issues of most importance right now.Appreciate if you have some experience about good or bad layer stacking.
