I have two seperated pcb one is power supply pcb and the other one is noise sensitive DAC pcb.
I put vias on both pcb to make a pin to pin power connection please see attached picture.
In power pcb i use noisy isolated dc/dc converter (switch freq. 100khz). To clean up noise, i use LC filter + cap multiplier right after isolation and then a linear regulator.
I must connect power supply ground plane to the DAC pcb ground plane. The question is, which location/locations is good to do that on both pcb?
