EEVblog #688 – How To Rework Solder SMD Chips – BTTF Time Circuits Repair!


Dave shows you how to rework and replace a blown SSOP surface mount SMD chip with ChipQuik, solder wick, and drag soldering. And also mentions other methods using a hot air gun and pre-heater.
Can he fix the Back To The Future Time Circuits and restore the timeline to it’s original order?
Bonus rant about the lack of PDF schematics in Github projects.

The BTTF Time Circuits were designs and made by Shackspace

      Yeah, I guess is no much of a deal to trow a pdf inside…
      But you see? You had to have Eagle and KiCAD installed long time ago. Is what makers use in designing open source projects. And I guess the author didn’t imagined that a holly pro will come down from his higher planes of existence to try his low-tech ecosystem. :))

      Dave, you had to do your injection with translation microbes (Farscape SciFi) before coming down here.

        I won’t mind a guide with steps that allow to build a working environment similar to the one used by the original dev. At least as a last resort to preserve sanity.

        • Vasile Guta Ciucur

          He tried KiCAD once…

            yeah, obviosly. He wants to get rid of anything that makes him loose time.
            In my case, i’d love to clone myself although i’m not sure some of my clones would be happy doing crappy things while i do the good stuff. 😉

      I’m surprised how great the 50fps looks. Thanks Dave!

    • Usually it’s bad form to put binary output files into your source control software, but they should put the pdf somewhere accessible. Of course, it may be a different thing if the program to generate the binary output isn’t freely available.

        I won’t mind a guide with steps that allow to build a working environment similar to the one used by the original dev. Sounds like a vital part of any open source project at least as a last resort to preserve sanity.
