I'm drawing up a small board for the Recom RAC10-12DK AC-DC converter. It can be made very compact, even with IEC input, fuse and output filter onboard. But to achieve that, I've to run the output tracks under the converter. Do I risk picking up radiated noise or are these little boxes shielded well enough ?

So, back to the drawing board or not ? ;)

Thanks for the answer. Yes, I have a topside gnd plane right now and the power lines running under it. The big squares are smd shielded inductors. Normally, I would populate either the left or the right side, it gives me more flexibility.

I guess my question should be: is it ok to use that topside gnd plane for the gnd output or should it be used only as shield ?
