Hey! There are SMT mountable IDC contacts with 2.54 mm
separation. They can make you crazy!! You MUST measure them for
connectivity and you must handle them with extreme care and few cycles!!!

9) SMT handles mechanical stress extremely badly. SMT-only mounted
   contacts is just braindamaged most of the time.

SMT has it's benefits, but some people that ought to know better try
to do EVERYTHING SMT, and that stuff is ugly and fails greatly.
The same clueless people beleive anything not running at 3.3V or lower
as just stupid old stuff... that it actually works better is not even
in their scope of understanding.

Sigh!

Sigh!
