Soldering a SPartan 3 TQG144 at home possibel?

Hello,

 

It is very easy to solder the Spartan 3 in the TQFP package. You can just use the "drag" soldering technique to get all of the pins soldered.

I've soldered lots of TQFP stuff at home, even the larger 204 pin packages. The drag method Jack mentions works reasonably well, you can also use that method to tin the pads and then reflow on a hot plate or in a reflow oven to attach the part. The key is to use plenty of flux and be patient and make sure the part is exactly lined up. I then wash the board with acetone and an old toothbrush to remove all the flux and use a lighted loupe to inspect for solder bridges.
