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. Its

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 the floating
ground is AC Cold
One of the major causes of emissions can be excessive loop areas caused by a
long return path for signal currents due to the division of the ground
plane. Review the ground return path for signal lines that bridge the gaps.
Ideally, the signal return path on the ground plane should be directly
