摘要： A layered heater (20) includes a resistive layer (26) defining a resistive circuit pattern having at least one bend portion (32). A conductive overlay (36) is provided on at least one of a top surface (38) and a bottom surface (40) of the bend portion (32) to alleviate the current crowding effect, thereby protecting the electric circuit from premature failure. Methods of manufacturing the layered heater are also disclosed. The overlay may be formed on the bend portion after the resistive layer is formed. The overlay may also be formed on a substrate or a dielectric layer that supports the resistive layer before the resistive layer is formed.

摘要： A method, system and scan lens system are provided for high-speed, laser-based, precise laser trimming at least one electrical element. The method includes generating a pulsed laser output having one or more laser pulses at a repetition rate. Each laser pulse has a pulse energy, a laser wavelength within a range of laser wavelengths, and a pulse duration. The method further includes selectively irradiating the at least one electrical element with the one or more laser pulses focused into at least one spot having a non-uniform intensity profile along a direction and a spot diameter as small as about 6 microns to about 15 microns so as to cause the one or more laser pulses to selectively remove material from the at least one element and laser trim the at least one element while avoiding substantial microcracking within the at least one element. The wavelength is short enough to produce desired short-wavelength benefits of small spot size, tight tolerance and high absorption, but not so short so as to cause microcracking.

摘要： Terminating the ends of passive electronic components entails applying a laser-ablative coating (70) to each of the opposed major surfaces (14 and 16; 36 and 38) of a substrate (10 and 34). A UV laser beam having a spot size and an energy distribution sufficient to remove the laser-ablative coating from multiple selected regions of the major surfaces is directed for incidence on the substrate. Relative motion between the UV laser beam and substrate effects removal of sufficient amounts of laser-ablative coating to expose the multiple selected regions of the opposed major surfaces. The substrate is then broken into multiple rowbars (48 and 50), each of which includes side margins (60 and 62) along which are positioned different spatially aligned pairs of the selected regions of the opposed major surfaces. An electrically conductive material is applied to the side margins to form electrically conductive interconnects (56 and 58) between each spatially aligned pair of the selected regions.

摘要： Improved systems and methods for laser trimming resistors printed on a substrate layer are provided. An exemplary embodiment measures a resistance value for each annular resistor and sorts the annular resistors into one or more bins based on the measured resistance values and target resistance values associated with each resistor. A laser trim file may then be assigned to each bin based on a predictive trim formulation, where each laser trim file defines a set of configuration parameters for a laser drill to conform each resistor with their respective target value. The laser drill uses the laser trim files to trim the resistors within each bin in accordance with the laser trim file assigned to that bin.

摘要： The passive component (1) has a first part (22) of a material with a first resistance value, which value can be lowered to a second value by laser trimming. The second value is at most one tenth of the first value and preferably less. Said material crystallizes in a laser trimming process, which locally heats the material to at least a transition temperature. Said material contains at least two different elements, which are preferably aluminum and germanium. The passive component (1) may be, for example, a resistor or a capacitor and may be part of a thin-film network of resistors, capacitors and/or inductors. In a resistor, it is preferred to have a second part (4) which contains a different resistance material with a resistance value lower than the first value and preferably higher than the second value.

摘要： A pulsed laser system includes a laser pump (14), a laser rod (12), a reflector (18) interposed between the laser pump and the laser rod, through which energy from the laser pump enters the laser rod, an output reflector (28) through which energy is emitted from the laser rod, a switch (20) interposed between the laser rod and the output reflector, and a control device. The control device allows a primary laser pulse emitted from the laser rod during the emission period to impinge on a workpiece and blocks from the workpiece secondary laser emission occurring during the emission period after emission of the primary pulse. The pulsed laser system is operated over a range of repetition rates, so as to cause laser energy emitted during plural emission periods at each repetition rate. A portion of the laser energy emitted is directed toward the target structure.
