Patent ID: 8866041

Claim:
A manufacturing apparatus of laser diode units, each of the laser diode units comprising: a submount; and a laser diode mounted on the submount, the manufacturing apparatus comprising: a holding stage that holds a submount bar in which a plurality of the submounts are arrayed in a row and are physically integrated and on which a plurality of solder members are arrayed in a row, a plurality of the laser diodes being respectively mounted on the plurality of the submounts, the plurality of the laser diodes including a first laser diode and a second laser diode, the plurality of the solder members including a first solder member corresponding to the first laser diode and a second solder member corresponding to the second laser diode and adjacent to the first solder member; a load application device that applies a pressing load to one of the laser diodes placed on top of the solder member and that presses the one of the laser diodes against the solder member in a state in which the submount bar is held by the holding stage; a heating device that locally heats the solder member in the state in which the submount bar is held by the holding stage; and a controller that controls the heating device and the load application device in a manner that the first solder member is locally heated and melted with the heating device and is bonded to the submount bar while the load application device applies the pressing load to the first laser diode, and thereafter, the first solder member is heated and softened as the second solder member, which has not yet bonded the second laser diode to the submount bar, is locally heated and melted with the heating device while the load application device applies the pressing load to the second laser diode.
