Abstract
PURPOSE: To form a high quality plated coat by electroless plating without causing defective throwing and uneven plating by adding metallic cations to at least one of a sensitizing soln. and an activating soln. used in a pretreating process for electroless plating.
CONSTITUTION: When a substrate of a nonconductor of electricity such as ceramics is plated, the substrate surface is cleaned and made hydrophilic degreasing, washing, etching and washing. It is then sensitized with a mixed aqueous soln. of stannous chloride and hydrochoric acid, activated with a mixed aqueous soln. of palladium chloride and hydrochloric acid, and immersed in an electroless plating soln. of Ni or Cu to form a plated coat on the surface. At this time, by adding metallic cations of Li, Na, K, Ca, Sr, Ba, Fe, Co, Ni or the like except Sn and Pd to the sensitizing or activating soln., a high quality plated coat is formed.
