Let's Make Robots!

Just made my first SMD soldering

Today I made my first SMD soldering. This is where I started:

FT232RL and SSOP28 adapter

And this is what I ended up with:


Looks pretty good to me. I haven't tested the chip in action yet so I can't tell if it survived the process. Following Sparkfun's SMD HowTo (http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=36) it took me about 30-45 mins from start to finish. I think I bridged every pin on the chip but solder wick really does miracles! If this thing works I have to say it wasn't that hard.



Update Nov 4, 2010:

It works like a dream, well almost. I had some issues with Picaxe 28x2 and data transfer from FT232R to 28x2 didn't work. It worked just fine to the other direction. I had problems with Picaxe 08M too but got it working after I started using pin 3 instead of pin 1 for serin command. I didn't read the manual very carefully for serxxx commands so it might just be a RTFM thing. With ATTiny2313 it works like a dream even at 250k baud.

Not much to say about it so I'll just post some pictures of finished USB Serial thingy. (Could do a new "Something else" but I'm feeling kinda lazy)

Testing with 08M, ProgEdit and Putty

ASCII characters 1-8 going to ATTiny and coming back at 250k baud speed.

That's about it.

Your no longer a smd virgin.  It looks like you had a tender and enjoyable experience.  The IC looks like she faired well too.  I was thinking at one point to make a Jig with a Magnifying glass & arm for the soldering iron to translate movements.  Maybe its overkill ... well Congrats Nuumio !

Excellent! - I have just ordered a few smds, tragically, I got the numbers mixed up in the order so I'll have to reorder - but in any case, your effort looks better than I could hope for - My challenge will be to mount them on home-etched pcb...

I routinely use a smd resistors, leds and caps, but no ics yet.

Let me know if you try any smd free-forming... that's a new world of miniscule horror.

SMD free-forming sounds like a fun way to fry your ICs. Unless you have hands of a brain surgeon ;-)


Perhaps we need the brain of a hand surgeon?

I keep them handy on the mantle piece for decoration - right next to the palm trees.

Looks pretty good! Good luck with your first test.

I had some troubles with it last night but now it's working. It looks like the Picaxe 28x2 I used to test this thing doesn't work like it's supposed to. When trying to read from input pin with serin command I get nothing or just some noise every now and then. Today I tried with 08M and it works. Although serin didn't work on pin 1 but it works on pin 3.

I'll update the post later with pics of my "serial board".
