      The excellent Australian web site EEVblog has put up a YouTube video
      showing ChipQuick chip removal "solder" being used in real time for
      multi pin SMD chip removal from PCB's. This may be of use and interest to
      Softrock builders. It may also be a repost, in which case, apologies
      :) Although costly, and probably having a similar low melt "solder"
      equivalent at a lower price, I for one will be getting some of this
      stuff!

        There is absolutely no "magic" in this solder wire. It's just good old "fuse
        wire" used in the 50's, an eutectic compound with lead, tin and (most
        important part) bismuth. The temperature of the eutectic is far lower than
        regular solder. If you have a "true old fashion" hardware store, I'm pretty
        sure they still have such "fuse wire" in stock and will happy to sell it...

        You can make your own flux with rosin (violin players and mountain climbers
        knows where to buy rosin crystals at low price) mixed with isopropyl alcool.


        Anyhow, a good reworking station is more useful if you play a lot with QPFN
        packages :-=

          Why do most of these sort of videos last so long? At least one can fast forward...

          The method I use is a hot air embossing tool.
          Make a hole in some aluminium foil for the IC and it protects the rest of the components.
          And some use one in conjunction with SMD soldering.
          And heatshrink and Birthday cards..

          Softrock ICs may be removed by using a piece of enamelled wire, anchored one end and slipped through the gap between the pins and
          IC. Pull horizontally to release each pin as it is heated with an iron.

          Somebody recommended fitting the Si570 a little off the board so a thin wire could go under it. I tried that, but others thought it
          a bad idea.

          Hi Chris, It s available in wire form like a stick of solder and is quite brittle. It s also available as a paste
