Very confusing, I know edge plating since 20 years but I don't think it is
the meaning here, I found ..

This is also a very good technique for containing the EMI radiation
component that is produced by the internal circuitry and escapes through
the edge of the board provided the edge plating is grounded.

You may be describing edge plating, I'll explain.
There are times when a connection needs to be made from the top to the
bottom of a board and the only real estate is the board edge.
The board is processed normally until electroless copper where it is
routed
to expose the edge needing the connection.
The board/panel is processed normally through final rout.
At it's completion those areas routed before 1st copper now have an
electrical connection between the top and bottom.
When viewed from the top/side it can appear as though metal were formed
or
wrapped around the edge I suppose.

Subject: [TN] Wrap Around Plating
Dear Technetters,
I am a bit confused about a terminology - I checked the archives with no
better understanding.
Wrap Around Plating
The occurrence and usage of those three words are no clear about what is
understood within the PCB industry ..
Are we talking to protective films / masks / resists
Or plating on surface, sides, of feature?
Or about a packaging including embedded features
Is this an other one we don't use but abuse?
Thank you for your help
