Greetings.
I have a 6 layer mixed signal board with the following stackup.
top
ground plane
Mid layer
Mid layer
power plane
bottom
In one corner of the board i have some really sensitive analog circuitry encased within a shield box. I'm wondering how beneficial it is for me to put ground pours on the top and bottom layer (encasing only the analog part) in addition to the internal ground plane. I'm not sure if this will help or deteriorate the performance.
All replies appreciated.
