[sdiy] toaster oven reflow

[Craig Critchley]

I tried this for a (non-synth) USB project that had a small QFP with 0.8mm
leads.  It worked pretty well, and certainly speeds things up vs.
hand-soldering tiny parts.  You don't have to build anything - it's just a
toaster oven.

You really have to watch how much paste you use and spend some time cleaning
up bridged pins, but that's probably going to happen no matter how you
solder QFPs.  If I had another project where I could only find surface mount
parts and I was making a PCB, I'd probably do it this way again.

I wouldn't use any oven used for food preparation for soldering!  The solder
paste consists of very tiny particles of tin/lead solder mixed into flux,
and I wouldn't want that stuff anywhere near food.  I found a cheap toaster
and dedicated it to the cause.
