There is an Old formula utilizing Iodine and Potassium Iodide. in Water.
        I believe it was 10-20 g/l I with similar amount of KI , run at
about 140-160 F
this is from memory , I have the formula in my office , I will return
there Monday , I will post the exact formula then.

Hello,
I am looking for a suitable etchant for Au films deposited on Ni, which
DOES NOT affect the Ni (i.e other than aqua regia). Could anybody help
me?
Thank you!
