What should I do to fix a PCB on my mouse?
What should I do to fix a PCB on my mouse?
I have an Xtrfy m4 wireless and I accidentally damaged a small part of the board. I’m confused about how many lines there are and how to connect it properly. If anyone has experience, could you assist me in figuring this out? Also, I’m not sure how to add images on this site, so I found the link here: https://drive.google.com/drive/folders/1...sp=sharing
Before taking off the PCB, was the mouse still working? You've contacted Cherry.
The mouse functioned properly once activated, yet when I power it on or connect it via cable, it still doesn’t establish a connection. The computer doesn’t recognize it as a device, which aligns with my understanding that the line responsible for transmitting information was the issue. I reached out to xtrfy before noticing this problem; I explained the issue and they admitted uncertainty, suggesting something might be internally damaged—possibly true. If the crack were larger, I would have discarded it and purchased a replacement, but this one is small and seems fixable.
Use a micro dremel to reveal damaged traces, then join them by soldering a wire to exposed contacts. There could be several broken traces. Warning - a good micro dremel will cost more than half of a new mouse. It might not be worth it unless you already have all the necessary tools.
You don't require a micro dremel, a glass fiber pen will do. Or if you're more traditional, a small screwdriver works fine—just gently remove the protective layer. (I wonder what it's made of?)
Yes, everything appears fine. I’ll apply some pressure to help again before attempting repairs, and hopefully they’ll provide a schematic for the board or at least a section of it that I require.
