Usually a breakage is due to a cold solder joint but also can be cause by extremely high temps, low temps, high humidity or vibration/shock.



For maximum durability on my own stuff this is what I would do. If I was using non insulated crimp terminals.

Make sure you crimp first and solder second. If you solder first and crimp second you will break the wire. Dont forget to protect your connection point with adhesive heat shrink.

Thats how the guys in the shop do the little eyelets is crimp them then fill the end with soldier, but a butt connector, never. They fail in moist floor boards in a Crown Vic, I can only imagine a military vehicle..
