All this being said, yes crimping is better and my preferred method is Molex.  However I don't have the crimper necessary for this job so I soldered...So did an electrical engineer who showed me...You can get by with soldering.  There is an inflexible container for the solder joints.  They will

When we need higher mechanical strength from a solder, we use 2% silver solder. It's a lot stronger and not terribly more expensive. Melting temperature is about the same. Len Moskowitz ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub

​Eutectic alloying is a fascinating effect​ - a metal like lead melting at 621.4°F is mixed with tin melting at 449.5°F and the resulting melting point is even lower at 361.4°F. There is no paste phase as with non-eutectic mixtures. For electronics it is a great idea to use a eutectic solder
