Calculating plating speed with Hull Cell

Q. Hi to all the experts of electroplating. I need your help regarding electroplating speed of an electrolyte: please tell me how to calculate the plating speed of a electrolyte using the standard HULL CELL panel?

A. Hi Veerendra

A Hull cell is not used to measure plating speed.
Its principle use is to determine the optimum range of current density or to diagnose problems with organic additives, etc.

Use your hull cell to find the best operating current density; then plate a sample panel of known surface area at this CD and measure the thickness.

Don't be tempted to run the process at the absolute maximum current density, however tempting to reduce the process time, as it will be more sensitive to small variations in the process.
