Hi all,

I just soldered 6 more Altera Cyclone II chips in the QFP208 package
for a project at work.  After about the 3rd one I finally got my
technique worked out so I could do them quickly (about 15 seconds per
side).  The pins on the Altera QFP208 package are very very flimsy
(unlike the Xilinx Spartan 3's in QFP208).  It takes a very delicate
touch when hand soldering to not deflect the pins sideways to the next
pad especially since I like to use the drag soldering technique.

On the OZY, as a minimum I think people will want the Altera FPGA,
Cypress FX2, and the RC networks pre-installed.  While you are doing
this you might as well have all the other SMT ICs installed along with
the resistor network packs.
