Etching Rate of FeCl3 to Nickel and Copper Surface

Etchant for Nickel, Palladium and Copper. Is there an etchant for removing Copper and Nickel; if possible Pd also. Is Nitric acid a good option?

I had difficulty in etching copper panel with one side plated with nickel by using FeCl3, could anyone told me the etching rate of nickel and copper?

You haven't given enough information to answer your question. Need to know concentration, temperature, condition of copper surface, etc. I suggest you use a test panel and measure the rate directly.

If you are having problems etching I would also suggest you look closely at the surface conditions to make sure you don't have something on the surface acting as an etch resist.
