Dear members:

I plan to etch four square-shaped electrodes on the surface of a PVDF film.
I intend to purchase the PVDF film from either one or both manufacturers.
One of them provides its films with a Ni-Cu coating and the other coats them
with Ni-Cr alloy. Now my question comes at this point: which etchant is
appropriate in each case? Have you come across any commercially available
products suitable for this need? Do you have any particular recommendation?
Thank you.
