There's at least one company that builds SMT to DIP adapters, so you
can plug SMT packaged chips into DIP prototyping systems and the like.
Of course manufacturers don't want to use DIPs.
Actually that's BS! The military and NASA both REQUIRE them. They're a
lot more resistant to vibration for one thing. Besides I didn't say
MANUFACTURERS, I said "individuals". MOST manufacturers are only concerned
with how cheap they can make the stuff, they don't give a hoot about
durability, reliability, repairability or anything else.
They are electrically
inferior. For that matter, they are also obsolete --
if they made DIP
packaged chips they would certainly be very low volume products.
I seriously doubt that.

I understand the preference for DIPs in amateur work, though SMT isn't
really all that hard. But I can't imagine any reason for wanting DIPs
in new commercial designs. They are bigger, slower, not RoHS
compliant, ...
