  • Publication number: 20200234984
    Abstract: A component mounting machine includes a control device that controls a wafer supply device and a component transfer device. The control device includes a die information storage section storing the position of the dies stored in the wafer supply device associated with a rank of the dies, a block information acquisition section acquiring the condition of the dies to be mounted on a block provided on a board, a rank designation section designating the rank of the die to be picked up by the component transfer device, and a position designation section designating the position of the die to be picked up by the component transfer device. The position designation section designates the position of the die so that the die having the rank designated by the rank designation section is continuously picked up over the multiple wafers stored in the wafer supply device.
