Hi.

Thank you for your links, but I already knew them.

Can you confirm the order of the following layers :

1 Top layer
2 Ground layer 
3 Shield layer
4 Bottom layer

The order would be it rather like this : 1 3 2 4 ???


Analog ground is connected in multi points together "bottom layer" to "ground layer" throught the "shield layer" ?

Hi.

Yes. The order of the layers is as you mentioned.

And based on the thermals on some plated through-holes connected to AGND, the AGND plane is indeed spread out on all layers.

Thanks,
Shine
