Abstract:
A solder-ball bonding device for connecting a first bonding surface to a second bonding surface, the first bonding surface being on a pad formed on a slider held by a slider holder of a disk device, the second bonding surface being on a pad formed on an end of a lead set on the slider holder, and the second bonding surface being set substantially perpendicular to a surface including the first bonding surface, comprising:a solder-ball holder having a stocker for stocking a plurality of solder balls and ball holding holes to hold solder balls supplied from the stocker in predetermined positions, the solder ball holder being set in a position at a predetermined distance from the slider holder so that the first bonding surface and the second bonding surface are at acute angles to a vertical direction, respectively, and so that a virtual line formed by intersecting the surface including the first bonding surface and a surface including the second bonding surface becomes substantially parallel to a horizontal plane; a vacuum pad having a sucking opening formed at a top, the vacuum pad being able to suck a solder ball held in the ball holding holes into the sucking opening, and the vacuum pad being able to carry and release the solder ball at a position where both the first bonding surface and the second bonding surface can contact or be close to the solder ball; and an optical device to apply the solder ball with a condensed beam by a condensing inputted laser beam, the optical device having a laser output opening to output the condensed beam, the laser output opening of the optical device being able to access the solder ball close to or in contact with the solder ball, the solder ball contacting both the first bonding surface and the second bonding surface.
