Abstract

An improved method for controlling magnetic quality of electroless plating in which the plated substrates are subjected to magnetic film deposition for a true plating time determined by offsetting the total plating time by the activation time, the activation time being the time for surface potential transients to decrease and steady state surface potential to occur.
