The desirability or not of ripple in electro plating
I need good information on DC current requirements for general plating, especially with reference to the desirability or not of ripple, and how much should there be/ can be tolerated. I do copper, brass nickel, tin silver and gold. I want to start doing small chrome items as well, say up to 50 square inches. What should the current considerations be?

Ripple is bad for chrome, 5% max at whatever load you use. Three phase takes care of this nicely. single phase works ok as long as you keep the load at 80 to 90% of max load. There are other methods of controlling ripple in single phase systems, but some have a very limited range that would comply with the 5% max. Electrocleaning does not care about ripple, and periodic reverse may be desirable for some cleaner formulations.
