How about our project of LM3886 layout

[AlivinCai]

Any suggestion is welcome!

Just one, though I think it rather crucial...

Just how are you going to attach the heatsink with all that PCB space behind in the way?

Those mini tracks running around signal side of 3886 might be too thin, not sure.

We will place the resistor(30k) at the bottom layer,

so the heatsink will be ok. We just use the thin trace round LM3886 for sheiding.

A Little off topic, but what pcb software are you using. that board looks really nice.
