Hand soldering QFN package?
 

Has anyone tried hand soldering leads on a QFN package? perhaps dead-bug
style using wrap wire? Or?

I have 20 or 32 pin QFN chips I'd like to play with but the tiny size is
rather intimidating. I have successfully soldered SSOPs.

thanks, Tom

Best way that works for me is using a hot plate to heat up the pcb to 170C.
then apply a drop of flux on the bottom of the chip, melt solder on the pcb
footprint and place to chip down. capillary action will direct the chip in
place.
