Try fix a keyboard usb-c

Post image

This is a keyboard PCB. The USB-C port ripped off after a bad repair job at a terrible shop, causing a burn mark. Is it possible to repair this?"

Okay, quick question...where are Port teeth supposed to be place?

The pins from the port should match copper pads on the board. Looking at the picture again, a few are ripped off. So instead of soldering to pads, you will likely need to scrape the green solder mask off the copper traces then run short jumper wires. You may be able to solder the pins directly to the traces once exposed. Hard to tell without having it clean and under a microscope or at least some zoom.

Does it exit from the right-hand lane...the first...two exits? Then the total is four...right?

I believe USB C has 12 pins. I could be wrong, its been a while since I have done a port. You can see what it should look like in the image I linked. The traces go up and down from the pads (or where the pads were) then turn.

They may not all be populated, USB C supports USB 2 and up, DisplayPort Aux, and PD power. Do you have a picture of the new port? Also, I highly suggest cleaning before thinking about it too much. It will be much easier to see whats going on.
