[sdiy] Ground planes

[David Ingebretsen]

Is there any value to adding a ground plane fill to a PCB for the typical
types of circuits for audio module? How about one on both sides of a two
sided PCB? Is there any difference in putting it on the top versus bottom?

I'm getting ready to send a board off to be made. It's easy to add it, but
I'm not sure the theory behind it other than even with "thermals", it's a
pain to solder pads connected to a ground plane. 

I've noticed some PCB's I've purchased have them, but many don't and I
haven't heard any artifacts either way.

Thanks,

David
