Fix for damaged PCB
Sometimes removing the components are not going well even for experienced modders so good to know what options we have when the damage is done. The surface of the card is covered by a thin layer of paint, what is coming off relatively easy by scratching the surface with a sharp blade or other tool, revealing the real size and way the copper on the surface. It will give the opportunity to have wider surface for soldering or bridge the missing pads. Against oxidation the surface can be covered again with nail-polish if necessary. On the following picture the connections around the OpAmp can be seen.
If the hole of the capacitor damaged a very thin wire can help. Solder one side to the remaining copper and lead to the other side of the hole then install the cap, then ready for soldering as normal. Or use the other side of the PCB and the leg of the component to bridge the missing bit. Maybe not fancy, but electrons don’t care, and easier as well.
