This point seems to be disputed, and I believe that the mil-specs and aviation rules come in on the side of crimp-only, rather than crimp-and-solder. A double crimp connector that has one crimp grab the wire insulation, while the other crimp grabs the wire, seems to be the preferred high end solution.>> ... Push fits are used in cars a lot- they nearly always fail eventually.Its been said before but - - Crimp connectors in automotive use ALWAYS fail eventually. Eventually can be very short. I always solder crimp connectors after crimping if I have any investment in their reliability.
The wire screw terminals on our driver board are high quality clamps, and haven't ever given us trouble (unlike the cheap ones on some boards we have gotten), but we are going to replace them with ring terminals anyway.* Screw down connectors will be of the "clamp" type in any quality equipment. "Chocolate block" type connectors where the screw end directly contacts the conductor have no place in mission (or life) critical equipment
