Professional PCB Repair
If you are serious about PCB Repair, you can make an occupation out of it. For example, see these folks: https://www.circuitrework.com/ Not to mention youtube channels such as Learn Electronics Repair.
Conductive Epoxy Application and then Remilling Boards
This is a way to reuse double sided PCBs, by applying conductive epoxy over and then milling new traces. See: https://hackaday.com/2025/05/04/pcb-renewal-aims-to-make-old-boards-useful-again/ and https://smartlab.cs.umd.edu/assets/pdf/pcbrenewal.pdf See also Solder
External Resources
- https://caps.wiki/wiki/Special:AllPages - Aims to document repairing electronics. Open wiki. Still in an early stage, not a lot of pages yet. A little dry, but some interesting resources such as: https://caps.wiki/wiki/Capacitor_Cross_Reference_Tools https://caps.wiki/wiki/Capacitor_Brands
