[hpsdr] [OZY] QFP or BGA?

[Alex]

I was checking with the folks that make the SMT manufacturing equipment. 
QFNs are nasty little things that even cause problems for the automated production lines.

Also board assembly costs are getting pretty cheap for small runs.
Personally I'd rather have machine assembled units, I'm getting too old to hand solder SMT.

Give me a "B", give me a "G", give me an "A";  what's that spell? "B G A"   : )

Clock in another NO vote on BGAs if there are any other viable
solutions. Granted, BGA parts will eventually need to be dealt with on
some of the planned designs but in those cases where there are
alternatives let's try to stick with the non-BGA solution.

While I am sure they _could_ be mounted in a non-professional
environment, I'm not sure I'd count on doing it successfully multiple
times. Leaded or semi-leaded devices are so much easier to deal with
either with hot-air or toaster oven technology (or even a soldering
iron..)

I'm going to talk to some of our BGA rework people and see what they
recommend for mounting BGAs outside of a production environment.
