METHOD AND APPARATUS FOR CARRYING CONDUCTIVE BALL

摘要

PROBLEM TO BE SOLVED: To securely mount a conductive ball such as a solder ball on an electrode of a work even when a carrier for holding the work is bent. SOLUTION: A solder ball 6 is vacuum-sucked into a suction hole 28 formed in a lower surface of a carrying head 23. A carrier 12 that holds a work 2 and is carried on a carrying passage is bent so that the work 2 held on the carrier 12 is inclined. The work 2 is resiliently supported on a resilient member 41 disposed in a recess 40 in the carrier 12. Once the carrying head 23 is lowered and hence the solder ball 6 makes contact with an electrode 4 of the work 2, the work 2 compresses the resilient member 41 and is rocked vertically to take a horizontal attitude so that all the solder ball 6 is securely mounted on the electrode 4 of the work 2.
