摘要： A method and an apparatus for perforating a printed circuit board are provided so that the processing efficiency and the board densification can be improved. In test processing, a conductor layer 50i is irradiated with a pulsed laser beam 4a whose energy density is set at a value high enough to process the conductor layer 50i while emission 23a from a processed portion is monitored. Thus, the number of pulses of irradiation required for processing a window in the conductor layer 50i is obtained. An insulating layer 51i is irradiated with a pulsed laser beam 5a whose energy density is set at a value high enough to process the insulating layer 51i but low enough not to process a conductor layer 50i+1 under the insulating layer 51i. Thus, the number of pulses of irradiation required for processing a window in the insulating layer 51i is obtained. The conductor layer 50i is irradiated with the laser beam 4a the obtained number of pulses of irradiation, and the insulating layer 51i is irradiated with the laser beam 5a the obtained number of pulses of irradiation. Thus, a hole is processed in the printed circuit board.

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 method for determining a position of a reference point in which there is no influence of aberration of a camera lens or the like, but an error caused by a failure in shape of an alignment mark can be reduced. An alignment mark consisting of a plurality of pattern portions (and background portions) centering at a design reference point is provided in advance. Positions of centers of border lines of the patterns are calculated. Obtained coordinate values of the centers are averaged in each axial direction. The averaged coordinate values are regarded as coordinate values of a machining reference point. Thus, even when a defect occurs in any pattern portion, an error caused by the defect is reduced so that the accuracy in machining can be improved.

摘要： A optical scanner control method and a optical scanner capable of positioning a mirror at a high speed independently of a rocking angle, and a laser machining apparatus for irradiating a printed circuit board with a laser beam by use of the optical scanner to thereby perforate the printed circuit board. In order to operate an actuator for rocking the mirror based on a deviation of a current position from an commanded value, a change in gain of the actuator is measured in accordance with each rocking angle in advance, and the manipulated variable of the actuator is corrected to cancel the change in gain. Thus, the influence of the alteration of a torque constant in accordance with the rocking angle can be suppressed so that the response characteristic becomes uniform all over a scanning region, and the positioning speed can be improved.
