First surface mount component

[solarwind]

So today I soldered my first surface mount component - a PIC32 100 pin
TQFP package with 0.4 mm pin pitch. It was perfect.

I would post pictures, but unfortunately, my camera is damaged.

I did it with a simple radio shack soldering iron, liquid flux, copper
desoldering braid and a TQFP adapter board.

I first put liquid flux on the adapter board's pads with the flux
applicator pen. Then I placed and aligned the surface mount component
on the pad. This was the most difficult part.

I then put some tape on it so it wouldn't move around and soldered a
few pins to hold it down. Then on the opposite side I used the drag
solder & flood method (albeit easy on the solder) and continued the
rest of the way - all around the chip. Some pins were bridged - so I
took some handy copper desoldering braid (this stuff is awesome) and
dragged it across all the pins with the hot iron. The excess solder
was effortlessness absorbed and I was left with a cleanly soldered 100
pin 0.4 mm pitch TQFP component!

Some of you may believe that I tend to ask too many questions
regarding seemingly simple topics such as PCB etching or surface mount
soldering - but it helps - because I got it perfectly the first time -
no mess ups.

Interestingly enough, when I did my motorcycle insurance course, the
instructor assured me (and was willing to bet) that I would drop the
motorcycle since I had not driven one before (but had studied it
carefully beforehand). Needless to say - I didn't drop it at all - or
lose control. I didn't take the bet though :(

I just hope this trend follows through till next week when I etch my
first PCB :)

Next up: etching a PCB for the PIC32 on a single sided copper clad board.

Congrats!

Would you mind sharing a link to the type of adapter board that you used?
I've never seen one before and would be interested to learn how it works.

It's nothing special.

Good for you... beginners luck! I've just spent half a day removing and replacing a
100 pin TQFP by hand to fix a short underneath the chip... only to find that after 5
mins of power on the short has magically come back again~!

Very nice selection of things, but, the surface mount boards are minimum
25 pieces. Woulds be nice to see smaller quantities, or even a selection
of a couple of half a dozen varieties. :)

I think Wouter sells similar things piece by piece
http://www.voti.nl/shop/catalog.html?PCBs

Not sure if he sells outside of EU?

Congrats! Yeap, a TC solder pen and braid does wonders :) Any links to your
work?

Surely you need to check again. I have bought one off's of these from them.
Qty         1    + 25  +  100 +
US$ (each) $1.50 $1.40 $1.30
etc

Took a 2nd look at the page. The way the page is displayed with my
Firefox 3.0.11, the prices are set down 2 lines relative to the
quantity. I looked at the "each", and there was nothing  next to it. The
first price was for "25+". Sorry for the misunderstanding.

I sent the webmaster a note to check it out. :).
