Hi Warren,
Yes, I do have one of those fancy soldering setups... but, I don't like
the way things are trending in the IC package department.
25 mils pitch wasn't too bad but, the DSP chip I'm looking at using has
pins on 20 mil ctrs.; And the Up-Converter chip is 19 mils -- Whoooo is
making up these numbers!!
I just get a mite frustrated when every new part comes in a new
(smaller!) package -- meaning a new PCB footprint to make up and
sometimes another set of tips for the soldering station (at $$$ per!).
Makes me want to built something (to compensate) where the filament
leads are fastened to the socket with ¼-20 bolts! :-)
73,
Marv WC6W
