Proper anode to cathode ratio for plating? What are the consequences if too low?

July 10, 2013

Q. We are electroplating Pd/Ni 60/40 alloy. What are the consequences of a small anode to cathode area (ex. <1:1)? Thanks!

A. Hi Tess,

Optimum anode-to-cathode ratio for Pd/Ni alloy plating is 1:1 to 3:1. Too low anode area may result rough plating, pitting and/or poor thickness distribution,

Regards,
David

A. Hello Tess,
You will experience lower deposition rates, less than desirable thickness distribution, and also plate more metal from solution than you want. If too low, anode polarization is also possible.
