After 23 years experience in preparing rallye cars, 15 years experience in electronics and mechatronics - yes I do!

And when we were using crimps (because we needed special connectors) we additionally soldered it, too.

The reason is simple: With crimping litz wires you´ll pressing them together in a certain order. At the first moment everything looks save, can´t move anything. But by the time (e.g. caused by temperature) and also with the movement the litzes beginns to move a bit and rearrange them. This can be the point where they start to get lose.

Unfortunately I had to learn this lesson on a hard way, had such failures in my rally cars which at the end costs me at least one time a win in a national championship. And in my business it costs me money...
