Basic kludges: 5 minute SOIC-DIP adapter @ Evil Mad Scientist Laboratories.

So, you’re almost done building the new circuit board when suddenly… Doh! We’ve got the right chip handy, but only in the wrong package!

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here:

Adafruit is on Mastodon, join in!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Ouch. Very ugly but I goess it works!

  2. Jesus, that is some horrible hack!

  3. gang – the point of this was for it to be a “basic-kludges-5-minute-soic-dip-adapter” – if you have better, more elegant and nicer looking way to do this in a bind, in less than 5 mins – please post a link to your how-to 🙂

  4. I like this solution better

  5. > You want ugly? THIS is UGLY! (not mine!)

    I admire the so-called ‘Manhattan’ construction, and it’s very skilled, but can’t make myself do it. My lil’ projects look almost like Printed Circuit boards underneath, but with wire…

    I *DO* love the SOIC hack. So many of the ‘good’ new ICs are now only SOIC, so that’s an alternative! VERY well done.

  6. In that situation, I’ve always superglued the SOIC package right side up into the center of the DIP socket, then tacked pieces of fine gauge wire (often magnet wire) between the corresponding pads with some solder.
    Pre-supergluing the package keeps everything in place to make the soldering easier (assuming your iron has a fine enough tip to get in there, and your hands are steady enough not to mangle the plastic), leaves the pins in the order on the datasheet, and results in a roughly DIP-height object when you are done.
    It is also _very tedious_.

  7. Honestly, it’s not much easier to use pre-made SOIC to DIP adapter PCBs because the clearance between the IC and DIP leads is so tight.

    Of course, I was really lucky…the last time I needed to do this, AdaFruit created a solution for me!

  8. @K Scharf –

    As I understand it, that style of tack-solder breadboarding is the norm for people doing radio frequency analog work. Plug-in breadboards don’t work due to noise, stray capacitance, etc.
