Abstract
Method and plating bath apparatus for setting the ionic strength of a plating composition using Donnan dialysis by flowing the plating composition along a first surface of a membrane while simultaneously flowing a deposition metal ion exchange composition along a second surface of the membrane such that the deposition metal ion crosses the membrane from the deposition metal ion exchange composition to the plating composition while an exchange cation different from the deposition metal ion crosses the membrane from the plating composition to the deposition metal ion exchange composition.
