    Does anybody know anyone or does anybody have experience soldering fine electronics? I'm talking fine as in soldering four wires to a computer logic board? Or advice? Thanks.

    It isnt too hard to do. Get a soldering iron for like 15 bucks at a hobby store or hardware store. Get some solder. You can get rolls for a couple bucks. Heat up the iron touch the solder to it and get a small bead on the tip. Put the wire youre connecting to the spot on the board and wipe the bead on the tip of the iron across the two. It should come off and connect the two pieces. If it is not perfect you can get another bead or melt the one you swiped across and manipulate it into place. The key is to not keep it sitting in one spot more than a couple seconds so it doesnt char the board.

    If your working on cicuite boards I'd recommend one with a thermostat so you can run cooler than the non adjustable. Thin solder would help as well.

    See if you can find a good you tube video similar to the job you are trying to do. Sometimes you can pick up some good hints. Practice on an old circuit board first until you are comfortable with your tools. Tin your iron. Tin the wires. Tin the tabs on the circuit board. Use flux or resin core solder. Flux cleans and helps the solder flow properly.

    I took apart a MacBook to replace the optical drive with a data doubler, but when I used my splunger to disconnect the subwoofer / right speaker wire from the logic board as instructed on ifixit I came to know that I has actually busted off a soldered connection. There was no connector there at all as Apple apparently did not use an actual connector for the early production of this particular model. I was doing this work for my sister. I have pointed out the location on the logic board with my splunger.

    hmmm. That looks tricky to get down without soldering the circuits together as the connections are so close together. Are you planning on removing the wires from the connector to attach them individually? I don't know how you could get the solder in place and keep it liquid enough to attach with the connector in the way.

    Correct, I plan to eliminate the connector and solder the wires straight to the board. I wonder if I could find anybody who's able to do this kind of thing for me as apple obviously isn't going to! lol

    Bring it when you head my way. As it happens I just brought my ee box back from work (along with all my mugs. Books and beer glasses!)

    we can take a look and ten to 1 we can get it done.
