Electronic – Should we remove unconnected copper island among connected traces


Currently designing a PCB I find out there are some copper island. I was wondering if we should better keep them or remove them and why ?

Is there any manufacturing risk of having those ?

Yes, you should remove it in most cases, because it can act as an antenna or cause other problems.

You can do this in Altium by selecting the 'remove dead copper' check box.
