    Default Can anyone here do SMT rework?

    If you have the tools & skills to perform SMT rework, please contact me. I have a small repair job that needs done, replacement of a 28-pin TSSOP.

    Thank you!

    I've used some of that solder temperature lowering stuff ( forget what it is called ) and then use a heat gun. You need to clean if off real good with solder wick.
    Soldering, I just use small chisel point iron and lots of liquid flux. I tape it down until two corners are tacked. I inspect when done with a microscope.
    The heat gun is what I use for shrink tubing and the micro scope is just a cheap scope.

    Chip-quik. I've used Cerrobend 158 filings (powder) and a 150W PAR spotlight to do the same thing. Use a toothbrush to clean things up.

    I vastly prefer using a hot air rework station to remove SOP, TSSOP, QFP, etc. Just make slow even passes round all of the chip legs in a circular motion then pick up the part with tweezers.

    Yep thats the stuff Chip-quik alloy. I suspect it has indium in it. I see one can get it from amazon. I'd gotten a couple piece of it from a friend. Works great. You just need to clean well when done ( you have to do that anyway ).

    If "here" is Oslo, Norway the answer is yes.

    The OP posted the same post on Lemon64 after I offered here so I guess he's trying to find someone closer.
