heat resistance temperature of flexible cables?

[penta]

Sorry for any rudeness or strange wording due to machine translation.

Trying to self-install.
I am wondering what is the heat resistant temperature of the flexible cable?
I have heard of this type of cable melting when soldered, so I would like to confirm.
I don't want to put as much load on it as possible considering the possibility of replacing it with another chassis later on.

It's made of polyimide. It should not melt when soldered.

(If it's melting, your soldering iron temperature is WAY higher than it should be).
