BALL MOUNTING METHOD AND SUBSTRATE-WORKING MACHINE

摘要

Provided is a substrate-working machine, comprising a work device that selectively executes the work of mounting a conductive ball onto a circuit substrate using a ball holder (82) and the work of transferring an viscous fluid onto the circuit substrate using a transfer pin, and a tray in which the viscous fluid is stored, wherein, when the conductive ball is mounted onto the circuit substrate, the viscous fluid is transferred onto the circuit substrate using the transfer pin and then the conductive ball, immersed in the viscous fluid, is mounted on top of the transferred viscous fluid. This configuration enables the conductive ball to be secured onto the circuit substrate by using the viscous fluid transferred to the circuit substrate using the transfer pin and by using the viscous fluid adhered to the conductive ball due to the conductive ball being immersed in the adhesive fluid, and enables the conductive ball to be appropriately mounted onto the circuit substrate using a large quantity of the viscous fluid.
