Patent ID: 8769809

Claim:
A method of mounting a component using an apparatus comprising a plurality of spindles respectively comprising nozzles, each of which is configured to rotate about a first pivot provided at a center of the each spindle, a head body which is configured to rotate about a second pivot provided at a center of the head body and substantially parallel to the first pivot, and the head body configured to rotatably support the spindles, and a controller configured to control the spindles and the head body to perform the method, the method comprising: performing a pickup operation comprising: rotating the spindle about the first pivot from an initial orientation to a pickup orientation with respect to the head body; picking up the component; and rotating the spindle from the pickup orientation to the initial orientation so that the component is oriented to a mounting orientation at which the component is to be mounted on a substrate, wherein the rotating the spindle about the first pivot from the initial orientation to the pickup orientation occurs before the picking up the component; and performing a mounting operation comprising transferring the picked-up component to a mounting position of the substrate during which each of the spindles is retained at the initial orientation with respect to the head body.
