How to Solder this Accelerometer

EMPTY_C

I am working on a project and i was hoping to use the freescale semiconductor part number MMA7331LT, but i don't know how to solder it... this it the the documentation i found:

Any help would be awesome!

If it's a one-off prototype put a small amount of solder paste on the pads and use an embossing heat gun. Drag-soldering should work, as well.

Yes... this is currently a one off prototype... i have never soldered like this before... is there some sort of articles i could read on it?

Wow, if you haven't already ordered the part, Parallax has this: MMA7455 3-Axis Accelerometer Module.

The nice thing is no soldering needed! I just got one in the mail and am attempting to talk to it with my Propeller PDB. I'm using a modified version of
the Propeller Object of the week, "SPI Assembly - Serial Peripheral Interface".

So far, I've been able to write to the chip's internal registers OK, but when I try and read the X, Y, and Z G-force readings, I'm not seeing the output I expect to see--which is probably due to pilot error on my part. Maybe Beau could hack together a Spin/Asm demo for this module?
