My feeling is that for the sort of things most of us
do here, a
turned pin socket is the most reliable of all. Yes, soldering the IC
directly may have a (slightly) lower risk of bad connections, but
given that we do (or at least I do) component level repairs, may want
to remove ICs for testing, etc, there is a risk to the PCB if the IC
is soldered directly. As you say, cheap sockets are cheap for a
reason. They do develop bad contacts!
One recalls those execrable low-profile cheap sockets from TI in the
early 70s. Horrible stuff.
Aren't in fact, all wirewrap (board+pin) board sockets machine-pin? I
don't recall seeing one that wasn't. Given the great track record of
wire-wrapped designs that says something, surely.
