  Just wanted to say nice job persevering through this. I know a lot of experienced builders who would have just said F it. Way to push through what surely was a difficult and frustrating experience. Glad you were able to fix everything. One thing that might be beneficial is using a little expoxy (permanent) or some kapton tape to affix the wires to the pcb so they don’t end up getting yanked or damaged. Nice work.
context: TLDR: massacred my PCB while de-soldering, learned how it works, fixed it all. 
  See horrifying pictures below, not for the fainted hearted.
  My deepest apologies to any soldering enthusiastic that would get a panic attack from seeing this.

  A few months ago, I was fortunate enough to find a Whitefox keyboard in a thrift store. Bought it for 15$. link 
  It has hako clear switches, a bit too heavy for my liking. So I decided to change them for something lighter. I set my choice on some Gateron CAP milky yellow V2. 
  First blunder of the build: 
  After lubing the first switch I get distracted and close the switch the wrong way. Sure enough, this bends the metal connector inside the switch. Lesson learned, the rest of the lubing went smoothly.   
  Time to de-solder: 
  Equipped with an old soldering iron and a decent solder sucker, I proceed with neither patience and care. It was a massacre.
  I did not know at the time, and soldered the new switches in. It all became clear during testing. Quite a few keys were not responding. 
  Luckily, I am not the first one being that bad at de-soldering. 
  Big thanks to laroberto for posting his own misfortune with a whitefox keyboard, this gave me the hope and help I needed. link 
  Fresh start with: 
  - new soldering iron.
  - new multimeter.
  - schematics of the board
  - Patience and focus
  First step: Diagnostic
  With the multimeter, I could see there were 2 types of issues:
  - burned/burned pads
  - broken circuit connections, between two switches or between the switch and the diode close by.
  Second  step: fix and test
  - Fixed each switch one by one, in some cases after fixing one switch some others in the same column would also work. 
  In the end, everything worked out well, and I'm extremely pleased with my patched up keyboard, that now sounds and types like a charm. 
  I can imagine I was also very lucky, not breaking anything that was not easily "reparable".
