Hi everyone, first I’m terribly sorry for the long delay but I had an atrocious amount of work who just poped up at the time and I wanted to have all the time I needed to focus on this.
Long story short, I’ve managed to get some practice from soldering practice boards and after a week or two of try and error I’ve managed to understand enough for me to start soldering back those capacitors on my switch’s motherboard.
At first I decided that I would make a post when I would have finished everything, but it is not the case. I am AGAIN comming here for help …
So first thing first, I’ve managed to clean up the board a bit more, since there where still some old solder in place.
Some important details , I think :
When I was practicing soldering techniques I used my soldering iron with a smal tip, I managed to solder/desolder capacitors at a 250C° minimum (I could only find lead free solder wire and it was supposed to melt at 225C°, but apparently not. It annoyed me a bit but I guess that’s fine).
On the switch board however, it just would’nt melt at that temperature. Not with flux paste, not with some soldering wick, not with anything.
I’ve finaly managed to make it melt and clean it by increasing the temperature to 400C°, I was not happy to do this but it wouldn’t work otherwise. There’s still a bit of old solder stuck in the holes of the usb port that I can’t take out but I will try again later.
Right now my problems are :
_I can’t for the life of me make the new solder stick on the pads of the capacitors. It just stays on the tip of my soldering iron or it just sits on the pads but it won’t stick on it. I’ve cleaned it as best as I can and try new tips just in case the old one was bad but it still doesn’t work.
_Second, I have managed to take the capacitors I needed out from the donnor board to use them on the (I hope) still alive one. But, after a whole day of doing all of this my hand kind of started getting NOT that stable anymore and the smaller capacitors jumped out of the tweezer… Now there are somewhere on the floor and there are so small that I can’t find them anywhere… So I need help identifying them so I can buy a lot of them.
So we are looking at that chip and the capacitors at the bottom of it :
And those 2 caps( two pictures just in case) :
So again, sorry for the long delay AND for the long post. If you have insight to share that would great, I’m not about to quit yet !
