METHOD FOR GENERATING LASER BEAM RADIATION TRAJECTORIES FOR PROCESSING SEMICONDUCTOR PACKAGES

摘要

PURPOSE: A method for generating laser beam irradiation trajectories for processing a semiconductor package is provided to easily produce a spiral trajectory by processing a via hole of a package with a spiral pattern which is automatically produced. CONSTITUTION: A via hole is processed by irradiating a laser beam to a mold unit of a semiconductor package along a spiral trajectory. One of spiral trajectory patterns is selected in the controller of a laser beam irradiating device. The spiral trajectory is generated by inputting information about the selected spiral trajectory pattern. A laser beam irradiation condition is inputted.
