Trace width for audio board

[Jeffrey Landgraf]

Experts,

My Schematic is ready and I will start layout of an audio board. Is there
any recommendations for trace widths? Board layout is not dense and will be
a 2 sided board. The signal is all low level i.e. +4dBm input and output.
I've done some experimental routing based on a rough layout of just a few
opamps and it appears 20 mil traces will fit nicely. Is there a rule of
thumb for the minimum or maximum trace widths for audio?

Thanks,
Jeff

It doesn't matter at AF.

I would use 12 mil traces, because they will fit between the 60 mil
pads I use on DIP ICs.
