Patent ID: 8091767

Claim:
A substrate manufacturing apparatus that manufactures a ball-mounted substrate and comprises: a ball mounting apparatus which includes a ball vacuum chucking apparatus including a vacuum chucking head that carries out a vacuum chucking process to vacuum chuck balls at edges of suction inlets formed in a vacuum chucking surface and which mounts the balls vacuum-chucked by the vacuum chucking head on a substrate, wherein the ball vacuum chucking apparatus further includes: a holding vessel that has an opening and holds the balls; and a vacuum chucking/holding unit that vacuum chucks and holds the balls held in the holding vessel on a front end portion thereof, and the ball vacuum chucking apparatus carries out a supplying process that brings the vacuum chucking/holding unit that holds the balls on the front end portion thereof and the vacuum chucking surface of the vacuum chucking head relatively close to one another to supply the balls to the vacuum chucking head in a state where air is being drawn through the suction inlets, wherein the ball vacuum chucking apparatus includes a rotating mechanism that rotates the vacuum chucking/holding unit, the vacuum chucking/holding unit is disposed at the holding vessel and is constructed so as to be capable of being rotated about a base end portion thereof by the rotating mechanism in a state where the balls are held on the front end portion, and the rotating mechanism rotates the vacuum chucking/holding unit during execution of the supplying process so that the front end portion that holds the balls faces the vacuum chucking surface.
