摘要： An improved method and apparatus for drilling blind via holes to connect between upper conductive layers and lower conductive layers of printed wiring boards with laser lights. The resin layer contacting the targeted conductive layer is drilled to remain the residual layer with laser lights, and the residual layer is removed with a UV laser beam whose energy density is lower than the decomposition energy threshold of the conductive layer and higher than that of the resin layer. The apparatus for this drilling has at least two laser paths. The spatial energy distributions are made top-hat-shaped with beam homogenizer units in the paths, and the diameters and the energy densities are adjusted independently.

摘要： An apparatus for machining a thin-film layer of a workpiece, which is a transparent glass on which a thin-film layer is disposed on a top surface thereof, includes a workpiece-underside support mechanism for supporting the workpiece in a vertical direction by an air floatation mechanism and a suction mechanism, a clamp device for gripping the workpiece so as to follow the movement in the vertical direction of the workpiece, and a machining head for machining the thin-film layer with a laser beam. The machining head machines the thin-film layer on the top surface of the workpiece by irradiating the workpiece with a laser beam entering through the underside of the workpiece. Further including nozzles, the thin-film layer is machined while the cooling medium is delivered from the nozzles disposed by the thin-film layer side.

摘要： There is provided a laser drilling method that prevents hanging, expansion, or crinkles of copper foil caused when an ultraviolet laser beam that requires no surface roughening is used for a thin double-sided copper-clad film. The drilling method of the copper-clad film comprises the steps of: using an ultraviolet laser as a laser beam; drilling after bonding a resin film to the backside of the film which is the opposite side to the laser-beam-incidence; and delaminating the resin film on the backside after drilling. The resin film bonded to the backside prevents the copper foil from hanging, thus allowing the laser beam to be efficiently applied to the copper foil, and allowing the copper foil to be completely removed by ablation. In the case of a blind hole, the resin film bonded to the backside prevents expansion of the copper foil. Crinkles can be also prevented.

摘要： A composite sheet whose product price can be reduced with a smaller number of manufacturing processes. A laser oscillator outputs a pulsed beam at a frequency f. A mask shapes the outer shape of the beam into a triangular, quadrangular or hexagonal shape. N pieces of time-sharing means time-share the beam to form N beams having a frequency f/N. N pairs of positioning means position the time-shared beams. A condensing lens condenses the beams. A rotating drum displaces a workpiece. A control means controls the time-sharing means, the N pairs of positioning means and a pedestal. The N pairs of positioning means are positioned to irradiate predetermined positions with the beams. The pedestal is moved. The time-sharing means are thereupon operated in predetermined order. The workpiece is machined to make holes whose outer shapes depend on the mask so that distances between sides of adjacent holes are equal to one another.
