I'd like to learn how to do electrolytic nickel and gold plating on
copper sheets. Any web resources/links etc. ? I tried to search on
google but almost all results were commercial companies.

My exact application is to
1. edm wire cut copper foil (100 microns) - about 10mm x 10mm piece
2. clean off the corrosion on the edges due to wire cut process
3. nickel plate and make total thickness 130 microns
4. gold plate about 2 microns.

(I'm not sure whether I need to do step 2).

Please help.

Thanks
Mike
