Laser marking apparatus and method for controlling same

摘要

In a laser marking apparatus, a rotatable index table is provided in an index unit. The index table is provided with first and second support sections for supporting lead frames. Positions of the first and second sections are alternately switched between a stand-by position and a processing position by the rotation of the index table. Laser marking is subjected to IC package surfaces of the lead frame supported at the support potions located at the processing position. The lead frames after the laser marking process are transported from the stand-by position to a discharging section by a transporting device. The lead frames before the laser marking process are transported from a supplying section to the stand-by position by the transporting device.
