Hi all,
I'm dealing with a PCB that has a floating section isolated from the rest
of the board for safety purposes (patient applied part).

Jeeez, I have just the opposite problem GROUNDING a PCB at a
certain location.
The device is a metal enclosed digital device, about the size of
a video cassett tape

Floating "grounds" on PCBs tend to be problematic, especially at high
frequencies. Minimizing the effective capacitive reactance between the
floating "ground" and the real ground will ensure that t
ly means that you have a larger potential antenna.

Hi all,
I'm dealing with a PCB that has a floating section isolated from the rest
of the board for safety purposes (patient applied part).
I found out some problems with emissions, due to the coupling between the
floating part and of the PCB and the earthed one.
