Calibration apparatus, calibration method, and manufacturing method for an electronic device

摘要

Provided is a calibration apparatus, including: a holder for fixing an electronic device; a first motor for rotating the holder with a first rotation axis as a center; a second motor for rotating the holder with a second rotation axis perpendicular to the first rotation axis as a center; and a stopper for restricting a rotational position of the holder about the second rotation axis to a range between a reference position and a perpendicular position reached by rotating the holder by 90 degrees from the reference position, in which the first motor rotates the holder to which the electronic device is fixed at a predetermined speed in each of states in which the rotational position of the holder about the second rotation axis falls in the reference position and in which the rotational position of the holder about the second rotation axis falls in the perpendicular position.
