  • Publication number: 20060046481
    Abstract: A manufacturing method for wiring circuit boards enhances product yield and promotes uniform electrical characteristics among the products by reducing fluctuations in the thickness of the electroless Cu plating film. In a plating bath (53) containing an electroless Cu plating liquid (EPL), wiring circuit board workpieces (100) are held in an upright position so as to leave gaps permitting distribution of the EPL. A bubble generator (57), which produces bubbles in the installation area of the workpieces (100), is disposed between the bottom of the bath (53) and the workpieces so as to help form an electroless Cu plating film (40) on each workpiece (100) and so that bubbles from the bubble generator (57) rise up along both sides of each workpiece.
