摘要： The invention relates to a method for describing a predetermined desired course (1) with a beam of particles or waves, wherein a movable beam-directing device influences the direction of the beam, so that the latter describes an actual course (3, 4). The deviation of the actual course (3, 4) from the desired course due to inertia is minimized by specifying a corrected desired course (2), which describes diversions at the point of direction changes. The invention also relates to the use of this method for laser structuring or for writing guard plates or dial plates.

摘要： To drill micro-holes in a multi-layer substrate having a first metal layer and at least one second metal layer, and having a dielectric layer arranged between two metal layers, use is made of a solid-state laser. The beam of the laser, in a first operation, ablates the first metal layer and, in a second operation, ablates the dielectric layer down to the second metal layer. In the first operation, the laser beam is set to a repetition frequency of at least 15 kHz, focused onto the first metal layer and moved in a circle corresponding to the diameter of the desired hole, in such a number of passes until this metal layer is cut through. Then, in the second operation, the laser beam is set to a preferably lower repetition frequency, directed out of focus onto the dielectric layer exposed in the hole and moved, with a circumferential velocity which is higher compared with the first operation, in one or more concentric circles, until the dielectric layer is ablated in the hole region. The effective energy density in the second operation is selected, by setting the defocusing and the circumferential velocity, in such a way that the effective energy density lies below the threshold for ablation of the second metal layer.

摘要： A method and device can be used to pattern both regions of a printed circuit board which are provided for coarse conductor structures and regions which are provided for relatively fine conductor structures of the printed circuit board. In each case, this can be done via laser processing. Both regions are firstly coated with a continuous metallization layer and covered with an etch resistor. The coarse conductor structures are predefined with a laser beam with a relatively long wavelength by exposing the metal surfaces which are not required. In addition, the fine conductor structures are also pre-shaped by processing the etch resist with a laser beam with a relatively short wavelength. Then, in a common etching process, all the exposed surface regions of the metal layer are etched away so that only the coarse and fine conductor track structures which are covered by the remaining etch resist are left. As a result of the removal of the rest of the etch resist, the surfaces of the conductor tracks which are produced are then exposed.

摘要： In order to produce a trench structure having steep sidewalls free of residues in an, in particular, glass-fiber-reinforced substrate, the substrate is provided with a conformal mask having cutouts corresponding to the trench structure to be produced. In this case, the laser beam is guided over the cutouts of the mask in such a way that the low-energy edge regions of the laser beam are shielded and that proportion of the laser beam which impinges on the polymer surface, at each point, has an energy density above a threshold at which the substrate material including a glass fiber reinforcement that is possibly present is completely removed.

摘要： A circuit arrangement is disclosed for determining the end point in an amperometric titration, in which the current between a working electrode and a counter electrode is measured as a function of the total volume of the titration agent added in volume units. The working electrode is operated with a constant polarization voltage with respect to a reference electrode and a closed-loop control is provided for holding the polarization voltage prescribed between the working electrode and the reference electrode at a constant. The prescribed rated value voltage is compared to the actual value voltage identified between the working electrode and the reference electrodes. The reference value voltage is prescribed with the assistance of a reference value generator, the actual value voltage is identified in a high resistance manner with the assistance of an impedance transformer and the reference value/actual value deviation is compensated by way of a summing integrator.
