Everything you need to know about crimping is here. Note the section on the type of crimper to be used vs. the $2 ones that most people have. Makes a big difference to have a proper rachet crimp.

Good article. Like almost everything else, use the right tool,the right materials and the proper technique and life is much easier.
Getting the connector crimped 360 degrees around the wire is essistial to getting the proper crimp.
I have seen and used connectors like those shown,but they had little "windows" in them to ensure the wire was fully inserted before crimping.
