After watching some videos on grounds / return paths / shielding etc I came up with a design that I was wondering if someone could assist in assessing below simplified diagram with notes to see if it is a good grounding strategy also considering PCB EMI/EMC ?
Simplified diagram attached.
I have this massage machine prototype that im going to install on a box and there will be a little of the coil vibrator chasis exposed. I already grounded it in the photo. Is this ok?ins
Hello, I am working on a high density circuit where space is very limited. It is 4 layers, with bottom GND, and a mid GND. The power electronics will carry 20 Amps. The image below shows the ground polygons I have. I am wondering if I should split the polygons as indicated by the green line...
Hello.
I'm building my first stereo amplifier, and I would like to share with you the ground/earth scheme I designed, for anyone to point errors in it, and hopefully make a better approach. It is based on local star ground scheme.
The amplifier is splitted in three boards:
