Problems solved by technology

However, as mentioned above, in the related art, since the spiral trajectory of the laser beam is firstly generated by CAD, and the digital information of the trajectory is provided to a controller of the laser beam irradiation device, any time only If the type of the semiconductor package to be manufactured changes, it is necessary to repeat the generation of the spiral trajectory

[0008] Therefore, since the spiral trajectory generation takes a lot of time, the productivity is low
