    First i apologize for my bad English because it is not my native language.

    I decided to open this thread in the idea that it will be useful to the community of this forum.
    I am not a great specialist in electronics, but i have some years of experience in microsoldering and especially in reballing. I have seen that there, are enough users who have faced in the process of repairing Switch with pads removed from motherboard in the process of replacement the USB-c port. This happens, when the person performing this operation uses inadequate tools or incorrect settings of the hot air station, namely temperature, the air flow or the flux, etc. I am trying here to present two methods of reconstructing the missing pads from the motherboard to the usb-c port. None of the methods belong to me, i also found them on the internet and i used them successfully in the in the repair process with destroyed usb-c pads.

    The first method.
    I used a connector ribbon cable and under the microscope i cut the small pieces of copper after i previously peeled them with a surgical knife, about the size of the original pad left on the motherboard. I scraped on the logic board of the switch with a surgical knife in the place where the pad was lifted until i removed the solder mask that covers the circuit and i managed to make the circuit visible. I put a little flux and with the soldering iron i put the tin on the circuit. Then carefully i put a piece of cut copper in the place where the original pad was and carefully fixed it with a little UV solder mask, which i dried quickly with a UV lamp. Then with the soldering iron i made a bridge with tin between the circuit and the new pad implanted on the board. That is how i proceeded to all the lifted pads.

    Method two is a bit more complicated.
    I cut 15mm from the connector ribbon cable and under the microscope, with the soldering iron i solder the circuits directly to the pins on the usb-c port. I mounted the usb-c port on the motherboard and the other end of connector ribbon cable i stuck it on the other side of the usb-c port. I scraped on the ribbon cable and i managed to make the circuit visible. Then i pulled wires from the ribbon contacts to the alternate points on the motherboard as in the diagram below and i isolated with UV solder mask.
    Both methods require patience and good microsoldering tools. A microscope or a good magnifying glass will require for a successful operation.

    At least include your PayPal.me link.
    One of the admins/mods should make this a sticky thread

    Difficult to say which are the pads that are directly responsible for the charge. You may need all the connected pins for the charging process to work. Remember that they are components on the motherboard that are responsible for charging the battery. I do not think it is as simple as it seems to connect only the power and ground pads. Someone who is very good should answer this. Maybe this helps you:

    The schematic of side B (tegra side) is marked in reverse according to my board and the testpads. (for eg D+ D-)

    Indeed. That is why I want him to add his pp.me link so repair shops that use his work can pay him

    It worked with any 0201 caps i have removed from mobile phone motherboards. I don't recommend it, but it works. Those are just for isolation purposes, if im right.

    Hi all,

    As it is difficult to order parts in these times, do you think it can start Switch without capacitors?

    Thanks a lot.
    Best regards
