Picture of Solder on PCB traces
Have you ever needed to solder a component onto an already completed PCB, or wanted to fix a broken trace or even mod something like a gaming controller? Well here's how!

Step 1: Supplies!

Picture of Supplies!
You won't need much for this instructable, just the basics.

You'll need:

1. The ability to solder (I'm sure you already know that by know)
2. A soldering Iron (the smaller the tip, the easier it is to solder small traces!)
3. Solder
4. A PCB or something with a trace
5. Something to scrape the trace with (an exacto knife or screwdriver or something else thin)
6. Something to solder to the trace
(Optional) 7. Helping hands to hold circuit boards
(Optional) 8. Flux

Difficulty:
Very Easy

This is infinitely useful to me, the demolisher of traces and abuser of solder. Really, I'm awful at this... Now I'll be able to fix a lot of silly mistakes! Thank you very much!

Great work. I've had some success repairing small traces using 28- and 30-gauge magnet wire too.
