'[EE] TSSOP Packages'

Hey,

Does anyone know of a prototyping board to handle TSSOP parts?  I am looking
at using an amplifier (
http://focus.ti.com/docs/prod/folders/print/tpa3120d2.html) that comes as a
24-pin TSSOP and I am not sure how to prototype with the part.  I am looking
at a way of placing this part into a breadboard.  Will an SSOP adapter also
work with TSSOP?

Thanks,
   Keith

This looks like the kind of thing you need:

I'm using something similar for my own prototypes. No, a SSOP adapter
won't work. SSOP and TSSOP are different sizes. TSSOP can be quite
hard to solder - it has a very fine pin pitch.

Cheers,
Zik

Keith,
     These Guys have helped me in the past. They make one of about
everything.

      Is this maybe what you are looking for?

Soldering manually TSSOP is a piece of cake. Using solder paste + hot
air even the SQF40A (5x5mm and 10pins per edge) is solderable from the
first try.
I have soldered 2.5Ghz SQF parts with success. My recommandation will
be "prototype directly on the final PCB design". In that way you'll
learn two different things: how to design multilayer PCB and how to
document yourself for such a job for creating successfully PCB in one
revision.

Tssop is not hard for soldering, plus a good solder paste/flux does help a lot. the LGA (Land Grid Array) and BGA (Ball Grid Array) is hard to handle, and require x-ray device for testing.

Doesn't TI have a dev board for this part?  Ask your local TI rep for one.

Solder paste + soldering iron works reasonably well too.

I'd second that. I would also recommend building in "test points", depending
on what you're doing maybe even one for each pin, something that you can
either stick a wire into, or grab onto with a scope probe. Really helpful
for troubleshooting. If the board space allows, you may not even need to
remove the test points for production. More likely though, what would happen
is you'll find yourself redesigning the board anyway to fix the boo-boos
you've made along the way -- this would be the logical place to remove the
test points.
