[sdiy] strange pcb layout practice.

[Nils Pipenbrinck]

Hi there.

I just had a view on a Korg Trinity output board (a friend of mine has to
resolder the jacks). I took a look at it and found something, that makes me
wonder:

On the pcb there are several places where they use 0 ohm resistors to
connect one ground trance with the other - no problem so far, it's a single
sided pcb, so they have to bridge here and there. What I don't understand
is, that they don't use one single jumper but 10 in parallel.

They do this most of the time if they "bridge" over a signal trace.

But why the hell are they using 10 or more bridges, and not just one? Is
this one of those tricks I don't know about? Is this good practice if you
don't want RF signals to stray into the signal?

Maybe someone knows why they do this? I can't see a good reason.
