Lifted too much solder - none left!
Hi,
I hope somebody can help me with this. I was soldering a few wires on an electronic board which has very fine contacts (Apologies for the terms but I am a real sunday solderer!). It was going fairly well until I used soldering braid to clean up one and ended up with no solder at all on the contact on the board. Now I seem to have a black dot instead of any solder on the point and therefore I cannot complete my work. Can anything be done to salvage this board?? Thanks!! |

jderudder:
You didn't "lift too much solder"..... you pulled up the solder pad, by probably using too much heat for too long. As another reply suggested you can run the wire through the hole and use a short jumper wire to connect to the circuit... unless, of course this is a multi-layer board and you pulled the plated through hole out, then you may be screwed. You may want to scrape the black dot with an exacto knife... if there is metal under there you can tin it and re-solder... in that case, you dodged a bullet and you are very lucky... go buy a lotto ticket.

Now I know why I should have got a proper soldering iron in the first place. I have one of those all ON or OFF and the heat was probably too high for this. I think my only option left is to solder some hookup wire directly on the pin of the chip. With a good iron this time, do you think this is feasible? |

You should pratice on some junk electronics that you don't need so that you don't screw up your good board more. I migt also suggest finding some wire wrap wire to do this because small wire is eaiser to deal with than large wire. - Mike - Mike |

You would not want to cause an intermittent after fixing the pulled pad issue. - Tim - |
