worth the hassle of trying to chase down phantom problems. This
goes for soldered designs as well as WW.
I'll 'third' it...
I will use nothing but turned-pin sockets (that's what they're called in
the UK) now. I once spent most of a day tracking down a fault that was
caused by a flaky contact on a folded-metal type of socket. Never again.
I've got more enjoyable things to do...
Speaking of machined parts versus something else...
Anyone notice how commodity PCs have screws that have clearly
been *cast* onstead of *turned/Machined*? Everytime you thread
one into a hole, you generate a nice supply of metal shavings.
Not good.
To get back on topic, when did this trend start? The IBM PC,
PC/XT, and PC/AT used machined/turned fasteners. Lots of classic
non-consumer hardware used various "captive mechanisms" instead
of plain old screws and bolts.
And how about sharp edges inside a chassis? Older hardware tends
to have spent a little time in the hands of a whitesmith, who
added lots of finishing detail like smooth edges that don't cut.
