I have a small board, the outline of the edge have two half circles, it need copper pated wall. I know we can use via if it is in the middle of the board. But how about the edge ?
The board outline is attached. Thanks for your help.
Is the edge plating to increase current carrying capability?
You are using threaded mounting hardware inserted through the half circles... Usually we can't risk metal shavings broken/scraped off by the screw threads, causing a short somewhere else.
