    Hi,
    Please consider cutting the pins close to the capsule to remove it and leaving only the pins on the PCB.
    Then remove the pins one by one with the soldering iron.
    In the end, use the solder plate, but only to clean the hole, which is completely free.
    For years I used this process, because a PCB cost a lot of money and the chip only cents!
    Don't take chances!
    Thanks for your work!

      Hi, yes this is a good method if you know for sure the chip is bad. I dmeonstrated it here - ruclips.net/video/5A7fzoQ3a34/видео.html

    Nice, thanks.
    When working on rare boards for specific use my way is to cut the pins of the top of the IC chip, then pull the pins one by one while melting solder whit iron.
    There are industrial board were ic's are pressed in the board, thats the only way posible.
    Destruction of IC, but its mostly logic or driver type, not to exotic.
    Boards are unobtanium.

    Great video. Nice explanation of how address relates to screen output and RAM IC.

    I've always been a fan of the manual pump, TBH :) x

      It works a treat. If only the Smart Card could do the desoldering too.

    I like your videos keep up the good work.
    I have a pukka Hakko de-solder machine, but I still prefer my RS metal green tube hand de-solder pump most of the time.

    Try one of the Green RS pro solder suckers, they're not cheap but we'll worth buying.

      Is that the manual piston style one?

      @@HappyLittleDiodes : Hi: Yep that's the style, quite a powerful thing to be fair. For smaller de-soldering jobs I tend to use that rather than wait for the de-soldering station to heat up, as I said they're not cheap but worth the money if you use it regularly.
