Today I learned all about the many different methods of pad repair! After watching a couple videos, I came to the realization that basically, people do whatever they can to make the pad work again.
YouTube Videos Watched:
- “PCB Solder Pad Repair & Corrosion Clean Up- the Epoxy Method”- https://www.youtube.com/watch?v=vx50YtEC2S8
- “Silver Conductive Pen- DIY PCB Trace Repair”- https://www.youtube.com/watch?v=WY3d8N21OAE
- “Quick Circuit Trace Repair”- https://www.youtube.com/watch?v=a5A61fIu0kk
The Methods Explained:
- The Epoxy Method- clean pad with flux, solder wick, and isopropyl alcohol. Use a flat edge to remove extra adhesive/solder mask. Then clean the pads again, and create new pads. Flux and tin the traces, then epoxy, solder the new pads on, and then epoxy again.
- The Silver Conductive Pen- a pen that can connect circuits by releasing conductive material. Thus, with a silver pen, you can remake your own pads and traces easily by drawing them on the PCB. Note: a squeeze and push pen is best for PCB work.
- Jumper Wires- tin a wire and solder it onto the traces you need replaced.
