JF, I have been in the MIL industry , so I'm not used to hunt for the
cheapest solutions. Anyway, for us it has been forbidden for decades to tin
the wires because of 'long time creeping' until there is no contact
pressure. Poff. ZZspffft. Instead we crimp metal barrels on the wire end.
There are lots of such stuff on the market. Not applicable on
microelectronics,though.
