| 03:14.53 | DocScrutinizer05 | Shapeshifter: sorry, I don't. I use separate 15bucks desolder pump |
| 03:15.08 | DocScrutinizer05 | and wick |
| 03:17.09 | DocScrutinizer05 | usually it simplifies stuff a great deal when you cut the component to remove into pieces, so you can pull one pin at a tme with a pair of tweezers or pliers while heating the solder of that one pin |
| 03:18.10 | DocScrutinizer05 | another alternative is hot air and reflowing all pins concurrently, so you can pull the uncut component |
| 03:19.15 | DocScrutinizer05 | unsoldering even a 3pin mouse button switch drives me mad without cutting the switch into pieces beforehand |
| 03:20.56 | DocScrutinizer05 | alternatively when you want to salvage the component, you might want to cut the PCB into shards so you can remove one PCB shard at a time from one pin |
| 03:22.25 | DocScrutinizer05 | for large heavy components you can trun the PCB component side down so components can fall out, the apply a torch to solder side of PCB to reflow large areas very quickly |

| 14:33.25 | Shapeshifter | DocScrutinizer05: I managed to desolder all 64 switches using the solder sucker... What an ordeal. First I tried to remove the solder from all switches (which are also held in place by a base plate) to remove the base plate, including switches from the PCB but there was no chance in hell that would have worked, because the slightest drop of solder holding a pin in place was enough to make this fail. I |
| 14:33.31 | Shapeshifter | got really mad and gave up, re-soldered all the switches and wanted to call it a day. I cleaned the PCB using KONTAKT and reassembled the keyboard but then discovered that since I had used so much solder trying to re-solder and re-suck the solder that some of the cleaning fluid, including sticky flux had gone into some of the switches, which were now sticking in the down position.... So I had dinner, |
| 14:33.37 | Shapeshifter | took a hot bath, calmed down and went at it one more time, this time de-soldering one switch at a time, pulling it from the base plate - repeat. Took me close to 2 hours but I got the hang of it in the end. It's not that hard. It just takes a lot of concentration applying heat just long enough and really sticking that sucker down firmly on the pin... Still a huge pain. A de-soldering tool would be |
| 14:33.43 | Shapeshifter | soooo much simpler. But those things are expensive! |

| 15:19.52 | Shapeshifter | DocScrutinizer05: by the way, I once used a 5 buck solder pump and it was abysmal. Now this one I used cost more like 25 but it's /okay/. Engineer SS-02 |
