METHOD OF ABRADING A HARDENED RESIN A method of treating a metal-plated board for the removal of a hardened, alkali-soluble resin layer therefrom, comprising the steps of: (a) contacting a surface of the resin layer with an aqueous alkaline liquid such as an aqueous sodium carbonate solution to swell the surface; (b) abrading the resin layer having the swollen surface, step (b) being preceded by or simultaneous with step (a); and (c) then washing the abraded surface with an aqueous neutral liquid such as water.
