Here are a few soldering tutorials that might be of interest to you.
These first two are your day-to-day standard soldering methods. There are many of these types of videos online.
This next set of tutorials is for high reliability “proper” soldering techniques. This is actually why I am writing this post. These are used in the aerospace industry. Be warned that these are tedious and time consuming methods to apply. You will note the use of a panavise which is a great tool for soldeing and electronics work. He also has a spring for holding the wires which I am not sure if that is a standard item or something he found. Comment below if you know.
