    Hi everyone!

    I learnt a new trick today for removing components from a computer board, or from a pcb with many components.

    If you want to scavenge lots of components from these boards in no time at all, this will help you.

    Rather than using a solder sucker and a soldering iron, use a plumber's blowtorch. Set it to low, and then heat up an area briefly before tapping it on the edge of a table and then all the components just fall out! You can easily remove 10 ics in about 5 seconds!

    You have to be very very careful with the application of the flame as there is a fine line between removing a chip and burning it. But the method can work very well. Done it myself.

    Be sure to hold the fumes in your lungs for a long time, don't let it go to waste!

    You could also use a heat gun. Just heat the opposite side of the parts you wish to remove.

    darn... Allen beat me to it... :)

    I use my gas soldering gun for desoldering, with the catalyser it can be used as a hot air gun and is adjustable from 200°C to 800°C, perfect for almost all components.

    If you are two about the job. It is often less stress on the chips. One use the heat source and the other pull the chip of the board
