[sdiy] pin headers on the wrong side of a PCB

Laurie, Tom and Pete,

Thanks for your responses.  Pete, I also had the idea of pulling the pins
out of MTA connectors and sliding the plastic part over longer pins, but it
seems like an awful lot of labour, and I'd prefer not to "misuse" parts in
that way if I can avoid it.

Laurie and Tom, I agree that right-angle connectors would be very
convenient.  However, I'm a little worried that the connectors could be
forcibly ripped off of the PCB (traces and all) if soldering on the same
side -- it would be nice to be able to also secure them on the other side
somehow -- that's the nice thing about those long Arduino pins.  In that
sense, Pete's idea seems safer.

I see that there are MTA pin headers that have no locking clip -- they are
just straight pins.  What do we think about making connections that don't
lock?  Of course, most ribbon connectors don't lock, but they are typically
two rows and quite tight.  Perhaps that would be good enough.  Would you
think that such a thing would ever actually come disconnected in a 5U
modular case?
