TechNet,

   What is the best technique to clean flux off of a polyimide flex circuit
after population?  Thus far, we have been cleaning the flex circuits with
alcohol but it is time consuming and tedious.  We use a machine to clean
rigid boards, but I am hesitant to use it for our flex circuits.  How are
you all cleaning your soldered flexible printed circuit boards.

                                Thanks,
                                Nancy
