Method for mounting a component

A method of mounting a component using an apparatus comprising a plurality of spindles respectively comprising nozzles and configured to rotate about a first pivot provided at a center of the each spindle, a head body configured to rotate about a second pivot provided at a center of the head body, and the head body configured to support the spindles rotatably, a power transmitting shaft connected to the spindles through a gear, and a controller configured to control the spindles and the head body to perform the method, the method comprising:

• controlling the head body to rotate about the second pivot and the spindles to rotate about the first pivot;
• if the power transmitting shaft rotates the gear about the second pivot in a first rotational direction when the head body does not rotate about the second pivot in any rotational direction, controlling the spindles to rotate about the first pivot in a second rotational direction opposite to the first rotational direction due to connection between the spindles and the gear,
• if the head body rotates about the second pivot in the first rotational direction when the gear does not rotate about the second pivot in any rotational direction, controlling the spindles to rotate about the first pivot in the first rotational direction due to the connection between the spindles and the gear, and controlling the spindles to rotate along with the head body about the second pivot in the first rotational direction due to connection between the spindles and the gear, and
• if both the head body and the gear rotate about the second pivot in the first rotational direction, controlling the spindles not to rotate about the first pivot and to rotate about the second pivot in the first rotational direction due to the connections between the head body, the spindles and the gear so that the spindles retain their orientations with respect to the head body.
