Thanks Gert
I want to read your advices with great attention. Just one immediately follow-up ==>This Misc layer, is it an extra layer for signal routing, as a Sbott3? Mvh Amund Fra: Gert Gremmen Sendt: 10. februar 2020 09:57 Til: Amund Westin <[email protected]>; [email protected] Emne: Re: [PSES] PCB layout technique - multilayer 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.

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.
