[sdiy] 0.100 pin header reliability.

I won't argue against 20 years of positives. But maybe your experience
would have been just as positive without soldering?
The reason I don't crimp-then-solder is because the Molex info sheets
for the KK series state specifically not to do so. They claim the
soldering actually makes it less reliable.
Regardless, I plan on switching to IDC type connectors. While the
crimp method is supposed to be a superior connection (Molex KK series)
the contact pins of the AMP connectors seem to sit more snug in the
housing and show less play when fitted to the header pins than the
Molex type.
  Also, I started using connectors as a compromise to the best
connections (direct soldering, no connectors or headers). The Molex KK
take a lot longer to do than the IDC method and I wasn't saving any
time compared to hard soldering the leads to the pcb.
