Hello, Using an iron, desoldering pump. I did not use flux. I attempted to desolder my mouse switches for Mouse 1 and Mouse 2, and replace them. When trying to replace the switches, the result was : Mouse 1 worked properly, while mouse 2 didn’t respond. Clearly there is an issue with it. On the back side of the PCB, the copper plate is clearly not even there anymore, while it looks like it’s fine on the front side. Question: Is there any way to salvage this? If not, If i had to redo this, what could I do better to make sure it doesn’t happen again? Here is what it looks like:

@imnen When doing any type of soldering always use flux and you can never use too much . I cant really tell from the pics but you may have broken a trace, there not really visible in the pics . When desoldering I myself prefer to use a heat station to have better control over heat and to not accidentally screwing up traces with my soldering iron. I also prefer wicking to a pump but thats just my preference and everyone has there own preference . without flux your probably not getting a clean surface and the solder isn’t flowing out well. You can make new pads by bearing out the traces and laying in new solder pads . most important thing to remember is flux is our friend . Just one last thing are you using the right amount of heat for the job and are you using the proper solder and flux . Go onto youtube and take lessons, gleen some knowledge from others who know what there doing
