May I suggest that you change the category of this post to - or repost it under  - the JLCPCB category.

If you want to have the inner portion of that routed hole plated, you need to specify castellated holes in the JLCPCB checkout. 

@cjohnson, I think the problem is that Fred has used a plated through slotted hole to try to create an edge plated profile. Assuming that the board was made by JLCPCB, they seem to have been happy with this technique. Whatever the process that has been used to cut the board out from the panel however, it has trashed the edge plating on separation. BTW, This is a continuation of this topic: [https://easyeda.com/forum/topic/plated-edge-area-dbffab47939a408b855386568ee520ea](https://easyeda.com/forum/topic/plated-edge-area-dbffab47939a408b855386568ee520ea) @Fred, It's difficult to give any meaningful advice because your project is private so only you can see it and you have not given any information about how the board has been cut and separated.

Edge plating will always be unreliable.  If you are using it for RFI/EMC continuity, you are far better off with the cupro-bronze spring clips or something like that.  Or even 3mm aluminium section bolted to the board.
