No board should be without sockets. Period.
Even in prototype boards, you should use that. They are cheap
comparing
to the price of your time for a future problem
diagnose, or for the care
of
the board in case you need to change one or two ICs.
Sockets are cheap,
love
them! ;o)
Actually, lots of boards should not have sockets!
For example, the RGB video combiner I'm designing at the moment, even those
couple of extra pF can spoil things. I'll also cite early double sided
boards, before through-hole plating - it is virtually impossible to solder
both sides of a socket. Add anything working above about 10MHz, and you'll
have it about right.
Oh, and anything you want to be reliable......
Remember all those "I reseated the chips in their sockets and it worked"
posts you've seen on this list!
