Plated Edges - How to design?

Good day,

In order to reduce the ESD risk on a capacitive touch sensing board, I would like to implement edge plating on the design in order to surround the edges on all four sides.

I am aware that a fully plated edge around the whole rectangular PCB-perimeter is not possible due to the bridges/tabs that connect the PCB to your frame.

Thea wrote in mid-2023, that edge plating was supported.

What copper clearances around the board edge do I need to apply that you know what planes shall be connected to the plated edge and which not/be pulled back?

Is there anything else I need to keep in mind in order to prototype this on your 4-Layer-ENIG pool?

Looking forward to hearing from you.
Best regards,
Yannik

To provide help, I would need to know which PCB design tool you are using.

Hey Thea,
Thank you for looking further into this. The EDA tool I am using is KiCAD (v8).

Before you ask, the layout work itself has not started yet, since I wanted to ask for clarification and possible caveats first.

Best regards,
Yannik
