ELECTROLESS COMPOSITE PLATING METHOD AND EQUIPMENT THEREFOR

摘要

PURPOSE: To prevent fine particles from being deposited on the bottom surface in the inside of a plating tank by providing a feed pipe of fluid to the lower part in the inside of the plating tank and moving the feed pipe of fluid along the bottom surface of the plating tank. ;CONSTITUTION: A rockable feed pipe 2 of fluid is provided in the inside of a plating tank 1. When plating liquid 20 is force-fed to a liquid feed pipe 13, plating liquid 20 passes through a vertical part 4a and reaches a horizontal part 3 and is spouted toward the bottom surface from a blowout hole. Fine particles deposited on the bottom surface are raised while being blown off and approach the material to be plated. When a hydraulic cylinder 10 is moved and a link mechanism 11 is driven, a feed pipe 2 of liquid is rocked and displaced as shown by A2, B2 and C2. Since the horizontal part 3 of the feed pipe 2 of fluid is moved along the circular arc-shaped bottom surface by holding the prescribed interval, plating liquid 20 is sprayed in the whole surface of the bottom surface from the blowout hole. The fine particles deposited on the bottom surface are blown off in the whole surface of the bottom surface and removed.;COPYRIGHT: (C)1993,JPO&Japio
