Surface mount soldering workshop

  • Sep 6, 2011 · 7:00 PM

This was discussed in the meetup last night... Everybody will put a 16 to 32 pin QFN/MLF (http://en.wikipedia.o...) chip onto a breakout board, bake it, add solderless breadboard headers, and hook it up to your Arduino. These are the hardest, smallest surface mount chips (with the pins on the edge). Most likely we'll use PCA9555 chips (http://focus.ti.com/d...) -- its an i2c 16-bit IO expander (get more digital in/outs on your Arduino!!) -- which you can take home... Also you can make a suggestion or bring your own chip if you want. I haven't contacted Sprout yet, but it looks like they want $5 each to use their space and the materials cost is probably another $5. I'm not sure how to use this meetup site. Right now I am trying to gauge interest.

    I would like to learn more about Charlieplexing and using XBees.

    Todd: I'd be willing to do more workshops if there is interest. What topics do people want?

    Here are the details I promised you:

    If you have other questions don't hesitate to ask on the blog. Thanks!

  • g.andrew.stone

    I had lots of fun & enjoyed sharing my techniques! Is it fair that I rate my own meetup? :-)

    September 9, 2011

  • Todd

    Thanks for the great workshop. Would like to see more workshops on other Arduino related topics.

    September 9, 2011

  • g.andrew.stone

    Awesome! Thanks for that -- it looks correct to me and everybody I'm sorry I didn't get to it but I've just been very busy these last 2 days!

    That deal extreme site is dangerous. I've been there before but never looking for anything I NEEDED (like solder paste) I always wanted a bluetooth OBD-II interface!

    September 7, 2011

  • g.andrew.stone

    Hi everyone! Thanks so much for coming! I'll send better details this evening I hope! Those DX links are the right stuff! Code is located at: http://i2cdevices.svn.sourceforge.net/viewvc/i2cdevices/latest/ioexpander/pca9555/pca9555.pde?revision=1

    Found the data sheet (thanks Brian, doh!) I can't figure out how to use the wire library to talk to the chip. Do i have to write my own?

    Here's the paste and flux I found on dealextreme:

    The datasheet's linked in the event description above.

    September 7, 2011

  • Kevin G. O.

    Were the code or datasheet links sent out anywhere?

    September 7, 2011

  • Kevin G. O.

    This was terrific and I learned a lot! The logistics were difficult with so many people, but Andrew did a terrific job and was quite patient with us. Additionally I got to talk to more people than I usually do at these meetups.

    Great job, Andy. I really enjoyed learning a new technique. Thanks!

    Andy did an excellent job presenting - I learned a lot, despite having come in with bare minimum experience with Arduino/other microcontrollers. It did get crowded at times and it was hard to see the chips baking, but other than that I got to see and do everything. It was a very well thought out workshop and everything went pretty smoothly. Thanks Andy!

  • Collin R.

    A little crowded at time but the presenter did a great job. And the project was just the right amount of work for the 2 hours (mostly).

    September 6, 2011

  • g.andrew.stone

    It should be fine; I ordered 30 chips and we are currently at 28 people.

    September 5, 2011

  • Steve M.

    Hi Kevin. Long time... You guys can have mine if there is a shortage.

    September 5, 2011

  • Kevin G. O.

    I know you've already ordered, but I'm now a +1, as I'm bringing my 13yr. old mentee. I'm hoping we can reserve one of the extra boards.

    September 5, 2011

  • Steve M.

    Dave. You are probably more current on hardware than I am. The last time I "taped out" a board it was by laying down Gerber tape (including chip pin pads decals) on a mylar drawing sheet. It wasn't quite as long ago as it seems. Board layout software was available but my cheap start up wouldn't buy it for me. Darn parents. ;-)

    August 31, 2011

  • g.andrew.stone

    Wow, 24 people is great! It might be a little crazy but that will just add to the fun! I bought 30 chips this AM so if it goes beyond that the late signups will not be able to bring home a "party favor" :-).

    August 31, 2011

  • Dave A.

    Awesome. I once was adept at building circuitry -- bulit Heathkits, my Sinclair ZX81 computer, and even got paid to lay out the prototypes for some semi-popular arcade video games in 1982. But now I'm a new beginner. I'll bring my arduino, cable, soldering iron, and laptop (with Arduino software / processing / visual c++ / Adobe CS5 installed).
    @Brad I'll try to remember to bring video equipment.

    August 31, 2011

  • g.andrew.stone

    @Avni: nothing is necessary. I will bring lots of stuff. But to reduce sharing, you can bring all the stuff you've got, like: Your Arduino, USB cable, and laptop. A multimeter, a soldering iron, a circuit board vice, an exacto knife, a cheap plastic mechanical pencil (will get covered in solder paste). A solderless breadboard & some jumper wires. Anything you want to show and tell after the SMT fun!!

    @curt: Yes this workshop will be fine for beginners

    August 30, 2011

  • Steve M.

    Curt. We're are all beginners here in one way or another. Please come.

    August 30, 2011

  • Curt S.

    I'm new to arduino but would love to participate if this ok for a beginners. I wouldn't want to slow the group down.

    August 30, 2011

  • Avni K.

    Hi Andrew - Can you let us know what we need to bring? Thank you!

    August 30, 2011

  • g.andrew.stone

    Hi everyone! If you can't make this date PLEASE PLEASE change your status to "can't go", because I will be purchasing the SMT chips very soon! The total cost will be $10 per person (5 suggested donation for the space, 5 for the PCB and chips). I'll also bring some extra breakout board PCBs if you want to buy a couple extra for your own use after the workshop!

    August 29, 2011

  • g.andrew.stone­ changed the date and time to Tuesday, September 06, 2011 at 7:00 PM

    The 6th or 8th work for me as well. 6th is better if i have a choice.

    August 27, 2011

  • Kevin G. O.

    The 6th and the 8th both work for me. Really looking forward to it!

    August 27, 2011

  • Brad K.

    I am out of town until the 14th, If someone could record this it would be great.

    August 27, 2011

  • g.andrew.stone

    Oops, Sprouts accidentally told me wed was free but actually it is booked. I asked them about either Tues 6th or Thurs 8th... any preferences?

    August 26, 2011

    I'm actually not able to the 7th at 7. Any other Monday, Tuesday or Wednesday in September would work, however. If it turns out I can't make it, I'll just have to hope I can attend the next one! :-)

    Sep 7 @ 7pm works for me...thanks for organizing!

    August 26, 2011

  • g.andrew.stone

    Hi everyone, tentatively I'm thinking of doing it Wed Sep 7 at 7pm. Any issues with that date? And BTW share this w/ your on facebook, etc if you want to. You don't have to be in the Arduino group to come!

    $5 solution for more IO pins on the arduino is a godsend.
    plus, learning to surface mount is a big plus.
