I've not noticed that. I use cost solely as
the criteria for
when to specify a socketed part on a board of mine. But, that
is OVERALL cost (which is burdened by in-warranty repairs, etc.)
Please do not take this as a slam, but have you done real floorwalking
amongst the assembly lines with your boards? Most design engineers have
not - many have never even seen an assembly line*. Depending on the
^^^^^^^^^^^^^^
As opposed to a 'line of assembly code' (aorry, couldn't resist).
More seriously, there is, I will agree, one heck of a difference between
prototyping and production. It makes no sense at all to socket most (if
any) devices in most production boards. It _may_ make sense to socket rather
more stuff in a prototype, or an experimental set-up.
I suspect that most of the stuff we do here (related to classic
computers, I am not talking about stuff list-members do as part of their
jobs) would come under the latter category. If you think of that
PDP8-clone board kit that's been discussed here recently, I would think
that almost all (if not all) of thsoe will he hand-assembled. Pop each
component in by hand and solder it. Nobody (I think) is going to use a
pick-and-place machine and a wave solder machine on it.
