There are sever pads missing when my meson chip was removed. Are they all fixable/repairable? And how do I know which ones are NC. I think most of them are but I’m not sure. Can some please let me know if there is a diagram to know if this is fixable or not?
Questa è una buona domanda?

The blue pads are NC.

@refectio Would you consider rebuilding 10 missing pads in such a tiny space a feasable job ? Just curious ;)
@arbaman I didn't have access to the picture when I posted my answer. It's not super clear but as far as I can see, most of the missing pads are NC. There are only two that have to be rebuilt; N1 is ground and is in a corner and D3 is important but luckily has an access point close by.
As for rebuilding 10 pads, I've seen some techs post some pretty amazing rebuilds so it's certainly doable. It's all about fine motor skills and to a certain degree...patience :>). I'd certainly do it if I felt I messed up my repair attempt or if it was a data recovery job.
Just to piggy back off of your very informative answer. I can make a jumper for D3 to the access point?
Thank you again for all your help.
Yes, D3 connects to C2439.
@minho Thank you for all the information. It is all truly appreciated. I will post pictures of the job once complete.

if you add a photo it might help people see what pads are missing
