The tolerance for 1 oz ED foil is .00014". I do not see this as
feasible assuming the plating target is ~ .0010"

Subject: [TN] Copper plating question
Good Day To All,
I have a copper plating distribution question. Is it possible to hold
the
pattern copper plating thickness to +/-.0002 across a panel. Anyone want
to
venture what kind of Cp and Cpk they might hold? Thanks in advance.
