    摘要: A drilling method and a laser machining apparatus which can shorten the measuring time of workpiece surface height and improve the machining efficiency in spite of irregularities of about 10-30 μm high in the surface of a table. Surface heights of the table is measured at lattice points in advance. Top surface height at a desired point of the workpiece mounted on the table is measured. Surface height of the point is arithmetically obtained using heights of four points surrounding the point. The difference between the measured height and the arithmetically obtained height is set as the plate thickness of the workpiece. Top surface height of the workpiece at a machining position is regarded as the sum of the plate thickness and the height at that position obtained from the table surface heights.

    摘要: In a machining method and a machining apparatus, prior to machining, an NC control unit makes an X-axis drive unit move a table based on examination conditions specified in advance. Thus, the NC control unit obtains a stabilization time required from the command-reach time of a poisoning command and till the stabilization of position response of the table within a predetermined allowable range. Likewise, for moving a drill in a Y-axis direction, the NC control unit obtains a stabilization time required till the stabilization of position response within a predetermined allowable range. At the time of machining, the drill is moved in a Z-axis direction to cut into a printed wiring board as soon as the obtained stabilization time has passed.

    摘要: An apparatus and method for maintaining a desired position of a collimated light beam are provided. An optical system includes one or more passive optical elements movably positioned in the beam path. Beam position is responsive to movement of at least one of the passive optical elements. The actual position of the beam is detected and compared with the desired beam position. An error signal is generated and the beam path is altered responsive to movement of one or more of the passive optical elements. In further aspects, beam shaping optics, such diffractive optics, are provided to shape the sensed beam portion. In still other aspects, thermal conditions of the laser may be monitored and a thermal map is provided to automatically compensate for estimated beam drift due to thermal conditions.

A compensator/remapper includes a compensator element and a remapper element. The compensator element receives an input laser beam having a range of input angles and lateral displacements and redirects components of the input laser beam into an aligned laser beam having evenly distributed and parallel components. The remapper element is illuminated by the aligned laser beam from the compensator element and remaps the components of the aligned laser beam into a shaped laser beam having a profile that is optimum for remapping into a flat top laser beam.

    摘要: The invention provides a method and an apparatus for forming a plurality of ultraviolet-wavelength laser beams, and a laser machining apparatus, in which the machining efficiency can be improved due to easy maintenance and inspection while deterioration of wavelength conversion means can be prevented to reduce the running cost. A laser beam with a near infrared wavelength output from a laser oscillator is branched into a plurality of laser beams by a laser distribution unit. Each branched laser beam is partially converted into a laser beam whose wavelength is ½ of the near infrared wavelength by a wavelength converter. An ultraviolet laser beam whose wavelength is ⅓ of the near infrared wavelength of the laser beam is formed out of the branched laser beam and the laser beam with the wavelength which is ½ of the near infrared wavelength by another wavelength converter, both the branched laser beam and the laser beam with the wavelength which is ½ of the near infrared wavelength being output from the wavelength converter. The ultraviolet laser beam is extracted and supplied to a portion to be machined, by a wavelength separator.
