It’s been a while since I have posted, so I have posted some videos on everybody’s favorite video streaming service, it’s all about how to solder and how to desolder.

Soldering is one of the most important skills for any hacker, learning basic electronics skills will expand your knowledge of the electronics world.


Desoldering not only allows you to recover old parts from broken, damaged or obsolete boards it also allows you to repair the bad soldering joints when you start out , trust me this will happen.

So this next video is all about desoldering.

    Just as a note de-soldering can be very tricky especially if you are trying to de-solder an I.C. or any multi pinned component. A trick I use to desolder components or even the whole circuit board is to use an air compressor instead of trying to suck the solder off the board I blow it off the board with compresed air. A can of compresed air may work but I suggest an actual air compressor with a fin nozzle.
    I first heat the solder up make sure it heats up well so that you can get it all off the board
    Ill heat it up with the air compressor nozzle sitting on the opposite side from the soldering pencil then when I feel the solder has been heated well enough I will blow the liquified solder off the board with the air compressor.

    After you are done with the component most the time the component will fall right off the board unless it has bent legs.
    Try this technique out and see if it works for you but through all my years of electronic work this is the absolute best way I have found to de-solder components and I highly recomend that you atleast try it just be careful not to blow the liquified solder towards you as it can cause burns.

    That’s a good tip Acetolyne thanks. I do need to improve the videos though.

    Thanks for the nice tut. Even if you read all books about soldering you might not get an idea how to do it right unless you see someone doing it.
    Aquired, processed, saved in my brains! Now going into test mode 🙂

    @Acetolyne: Did you ever have the case that you messed up the board with solder while blowing it off? Does the solder cool down fast enough to not stick on any other parts? What do you have to take care of just for the case?
