Hi everyone Bonjour JP
So far it's been awesome but i manage to mount the CN3A on the wrong side.
it took me a bit of work with a solder sucker but finally manage to pull it out.

Now I can see some coper (i guess) from the pcb and I'm really concerned I've ruined !
I'd like to know before soldering on the right side this time..

Can you tell me what you think ?
Merci d'avance, Vincent

Check that the vias are OK. They connect the top and bottom pads.
What is your PCB revision?

REV1.3

Well I checked with the multimeter the top with the bottom of the damaged pads it seems there is continuity!
The damage is only on the surface of the pcb but some pads seem to touch with the copper wiring so I was afraid.

DO you think it's fine ?

Thanks JPK, 
I triple checked.

There is continuity everywhere. 👍
