Abstract

PURPOSE: To perform plating stable over a long period by measuring the concn. and refractive index of an electroless plating soln. and automatically replenishing the consuming components of the plating soln. or automatically refreshing part of the plating soln. by these.
CONSTITUTION: An electroless plating soln. 2 is taken out from a plating cell 1 and is circulated by a circulating pipe 6 provided with a concn. detector 3, a refractive index detector 4 and a pump 5. When the concn. of the plating metal ions etc. in the plating soln. decreases, the concn. detector detects this and operates the solenoid valve 19 of a replenisher replenishing mechanism 16 for consuming chemicals, thereby automatically replenishing the concn. decreased components of plating metal salt, reducing agent, pH controller, etc. Also, the conductivity of the plating soln. is measured with the refractive index detector 4, based on said results, it drives a scooping mechanism 20 which in turn causes part of the plating soln. to be scooped out by a pump 22 and a required amount to be scooped out from a replenishing mechanism 23, whereby the replenishers for consuming chemicals are supplied into the plating cell 1, thus the plating soln. is refreshed and the vat period is considerably prolonged.
