Double-sided soldering with a SMT oven


Double-sided soldering with a SMT oven… in our weekly chats, people asked how the machine does it, kinda like the human, but automated – the glue thing, that is.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

  1. This is a bit overkill — I don’t bother with the glue, the solder tension will hold most SMD components easily when the board is flipped over (so just do the layer with the heavy connectors last). You do have to make sure the board is supported at the edges, however.

  2. That’s cool. Where can this switch activated solder paste dispenser can be purchased ?

  3. David is right. I’ve soldered at least 10 double sided PCBs just by putting them upside down in a converted toaster oven and nothing ever fell off.

    The air pressure activated syringe is very nice though. Normally I use a paste screen but this is much better (read cheaper) for doing a single board.

  4. Even larger components that might fall off could be supported with some kind of fixture or none at all depending on the height of other components on the board.
    I worked at a CEM for several years and usually the only time SMD components were glued to the board was when they were going to be soldered with PTH components through a wave solder machine.

  5. Er, did I miss something, really cool equipment and all, but do they keep this engineer in a dungeon?
