[Amps] Stripping Litz

[Manfred Mornhinweg]

Litz wire most commonly has polyurethane insulation. This is solderable 
- you don't need to strip it!

Just set the soldering iron to a slightly hotter temperature than 
normal, then take the iron and common rosin-cored solder wire, and 
slowly start tinning the Litz wire, starting from the cut end.

By starting from the end, rather than some distance away from it, you 
immediately tin the end surfaces of each tiny wire, thus coupling a lot 
of heat into the copper. That way the film insulation gets heated from 
the inside and the outside, making it melt down rather quickly.

Instead if you try tinning the Litz wire at a point where it hasn't been 
cut, you are only applying heat to the outside of the exposed isulation 
film sections, while inside them the copper quickly carries the heat 
away. That makes it far harder to solder through the insulation.
