Question How to repair pcb in my mouse

[ArsenK]

I have Xtrfy m4 wireless and i accidentally broke a small part of the board, I don't understand how many lines there are and how it should be connected, if someone knows and understands this, please help me figure it out. I don` t know how to add image on this site, so there is link on google drive: https://drive.google.com/drive/folders/1ApxS4oBO9QtY3xFdR0GC1S4JlZfni_aS?usp=sharing

Prior to removing the PCB, was the mouse still functional?

Have you reached out to Cherry?

The mouse worked, now when I turn it on or connect it with a cable, it receives power, but does not connect, the computer does not see it as a device, as far as I have already understood it was the line that was responsible for transmitting information. I contacted xtrfy even before I saw that this was the problem, I described to them what was wrong with the mouse, and they told me that they could not say anything for sure, maybe something was really broken inside, they were right.

If this crack was bigger, I would have just thrown this mouse away and bought a new one, but this one is small, and I think it can be fixed.

You would have to source the PCB from Cherry or another mouse.

You might be able to bond/glue the broken area to stabilize the current PCB to keep from flexing.

Was anything else damaged?

Use a micro dremel, expose broken traces,
then connect broken traces by soldering a wire to exposed contacts.
Might be multiple broken traces.

Note - a proper micro dremel will cost you more than half of a new mouse.
Probably not worth it, unless you already own all the tools necessary.

You don't need a micro dremel, you can use a glass fiber pen.
Or if you are ghetto, like me, a small screwdriver and very very carefully, you just need to scratch away a little bit of protective layer.
(Which I think is just plastic? )

No, everything else looks good, I will massage to support again before trying to fix anything myself, maybe they will give me a schematic of this board or at least a part of it that I need.

I'll try to use what I already have, and if it's not enough, I won't try to fix it.

Okay, thanks, I'll try it. Yeah, it's a kind of varnish.

PCB can be multiple layers.
Good luck digging in more than top layer with a fiberglass pen.

Yeah because a mouse is gonna have multiple layers....
Or because someone with minimal experience is not going to completely ruin a multilayer PCB if they need to go beyond the first layer.
