Technical Advise on Acid Stripping Polyimide Copper Wire
Question Posted Thursday November 18 2004, 10:40 am
I wonder if you may be able to assist me with a technical issue I have.
We strip the polyimide insulation from the 33 AWG copper wires using sulphuric acid.
Could you advise what effect this will have on the wire properties after it has eroded the outer insulation?
Will this make the wire brittle and easy to break?
Will any residual acid left beneath the insulation and not cleaned away carry on reacting with copper wire and eat away into copper and make it thinner and weaker?
