I successfully desoldered the LCD connector, but unfortunately when I was wicking the factory solder to tin the pads, I rubbed off some of the solder mask. Does anyone have advice or a diagram I can use to make sure all the traces still work? It would also help since I think I need to run jumper wires on the scratched off parts. The first 2 images are the before, the next 2 are the aftermath.
Questa è una buona domanda?

I’ve got a board and I’m trying to find the traces for you. I’m not done yet but I’ve got somewhere for you to start at least. According to my testing all these pins should be connected to ground.
Hope that helps. I’ll keep looking for the other pins but it’ll take time. I’ll get back to you when I get more info.
Have a great day!
Edit:
Here’s some of the pins. These are the ones that are on this side of the board. Working on the others still.

Thank you so much! If solder is sticking to the exposed parts I scratched off, does that mean the copper is still there and I do not have to fix the traces?
Yeah most likely they’ll be fine. Sorry I haven’t gotten back to you with the other pins but I’m working on it. Hopefully I’ll get back to you later tonight or possibly tomorrow with the rest.
@albertg87002 I see. Thank you so much. Do not fret as I am in no rush and you're doing this out of the goodness of your heart
Ok, I’ve gotten done some of the pins. I’ll update my original post with the picture. All the pins/pads of the same color should have continuity between each other. Unfortunately the other pins are more difficult to trace because they go through the board, but I’ll figure it out and update you when I do.
With your outlines, it appears that I just scraped off the solder mask and none of the connections were damaged. Thank you so much for the help!
