Folks


        For an outside layer,  we generally specify 0.5 oz copper with 0.001
inch of copper plating on all conductive surfaces.

        IPC-6012, Table 3-9 lists the minimum thickness after plating as
.0013 inch.

        Can anyone please tell me what the maximum thickness, after plating,
might be ;  and what affects this ?
