Abstract
A conductive ball transferring apparatus including: an arranging member having in its top face a plurality of recesses in a predetermined arrangement pattern each capable of receiving one conductive ball therein; a tilting mechanism for tilting the arranging member with respect to a horizontal plane; a speed controller for controlling the moving speeds of the conductive balls that move along the top face of the tilted arranging member in a direction the arranging member has been tilted; and a transferring head for picking up the conductive balls arranged by the arranging member and transferring them onto predetermined positions. With this structure, the moving speeds of the conductive balls are stabilized and the conductive balls are arranged into the recesses quickly without fail, and thereby the transferring head can pick up these conductive balls onto predetermined positions promptly.
