Good morning,

In many of our designs we use Litz wire.  To make a connection with Litz wire the enamel coating from each strand must be removed.  Historically we have used a small solder pot to tin the ends of the Litz wire.  Currently we have a situation where these tinned wires (about 20 AWG) are breaking when bent around a turret connection.  Initially we thought it was due to the solder pot having been turned up too high, but I just ran some tests with the pot at normal temperatures and the wire is still brittle.  (Gee, what is my "standard" temperature.... just measured it at 900°F.... oops, that's a little high).

What temperature do you folks run small solder pots at?  Should I be in the 700-750°F range?

Are there any other thoughts on why the wire is so brittle?

Thanks in advance,

Phil Nutting
