Conductive ball mounting method and surplus ball removing apparatus

摘要

A conductive ball mounting method of the present invention, includes a step of, arranging a mask (40) in which an opening portion (40a) is provided, on a substrate (1) including a connection pad (C1), arranging a conductive ball (62) on the connection pad (C1) through the opening portion (40a) of the mask (40) by supplying the conductive ball (62) onto the mask (40), separating the substrate (1) and the mask (40), in the step, an extra conductive ball (62) left on the mask (40) drops through the opening portion (40a) of the mask (40), thereby a surplus ball (62a) is mounted on the substrate (1), and removing the surplus ball (62a) on the substrate (1) by making the surplus ball (62a) adhere onto an adhering head (78).
