Abstract: For the manufacture of composite panels (16) it is proposed that they be held essentially upright by means of holding devices (17) and that welding by means of a laser welding plant (11, 13) be performed in this position. This affords a considerable space saving compared with the conventional horizontal arrangement in which the composite panels are processed and handled.

Abstract: A method for fabricating a printed circuit board includes the steps of: fabricating a printed circuit board having at least one collapsed portion; depositing a first solder resist in the collapsed portion; exposing the first solder resist-coated printed circuit board at a pressure lower than atmospheric pressure for a predetermined time; coating a second solder resist on the entire surface of the printed circuit board; and drying and hardening the first and the second solder resists. With this method, when a solder resist is coated, since an air space does not remain in a blind via hole, the reliability of the attachment between a printed circuit board and the solder resist layer is increased.

Abstract: A pressure gauge or monitor is attached to a soldering iron so that the pressure with which the iron is being applied can be precisely monitored. Such a pressure monitor on a soldering iron can be used to monitor the pressure applied with the soldering iron when forming a solder electrode on an anti-reflective film of a cathode ray tube. This allows such electrodes to be consistently and optimally formed for grounding the anti-reflective film.

Abstract: An apparatus and method for welding a shaft having an open seam defined between opposed longitudinal edges. The method comprising passing the shaft along its longitudinal axis through an array of pressure rollers which contact the surface of the shaft at a plurality of discrete points and compress the shaft by applying inwardly directed radial forces to the shaft. An electrical resistance welding assembly welds the seam while closed by the pressure rollers.

Abstract: A method is available for repairing metallic components such as gas turbines, which have mechanically weight-carrying grooves, where the longitudinal edges of the grooves which exist on the component surface are largely in a plane and their actual contour deviates, at least locally, due to removal and/or displacement the component material from the desired contour. The method begins with abrasive blasting of the groove surfaces, followed by closing of the open groove ends by build-up welding, and subsequent filling of the grooves with soldering powder. The soldering powder is heated to liquefaction, then cooled and solidified in a vacuum, and the desired contour of the groove is then machined.

Abstract: By utilizing a roll bonding process and appropriately forming steps, a load bearing structure is created which is capable of handling and appropriately transferring loads. One preferred method includes the combination of roll bonding and hydroforming to efficiently create structural components. While various product configurations are possible, one version includes a waffle-type structure produced by appropriate roll bonding of material sheets. This waffle-type structure can also undergo additional forming steps to create several structural components capable of handling and carrying loads in a very efficient and effective manner. More significantly, this process enables the use of structural aluminum for load bearing components which are efficiently and cost effective when manufactured.

Abstract: A method and machine for deburring the burr which is formed when wires are butt welded is disclosed. The machine comprises a deburring head which has a pair of opposed deburring rollers mounted thereon. Each of the rollers has a milled surface formed therein. A linkage is connected to the rollers to cause the rollers to rotate when the linkage is moved between first and second positions. When the linkage is in its first position, the milled surfaces of the rollers face one another to enable the wires and burr to be positioned therebetween. As the linkage moves to its second position, the circumferences of the rollers engage the burr to roll out the same, thereby providing a substantially smooth, cylindrical surface where the burr was located. The method of deburring is also disclosed.

Abstract: A method for designing a weld fixture. The method includes modeling a set of distortions produced by applied mechanical forces on a material to be welded, modeling a set of distortions produced by applied thermal forces on the material to be welded, determining a set of reaction forces at a series of locations on a simulated weld fixture as a function of the modeled distortions, and designing a weld fixture as a function of the set of reaction forces.

Abstract: Economical production of configured, laser-drilled, high-precision, ultra-miniature multiple-via-hole patterns is accomplished by multiplexing the homogenized, shaped, nearly-collimated output of one or more high-power excimer lasers into a set of beamlines, differently configured at different depths through the thickness of the substrate. A substrate delivery subsystem provides a continuous supply of film substrate strips or segments, which may be blanks or intermediates. Various stencils in a mask provide a cup-shaped partial hole, which is subsequently provided with a mating stem hole. Each stem portion of each hole is laser-drilled into the bottom of the cup portion from either above or below to form a via-hole with a desired configuration, such as stem-glass (or cup/funnel), as desired for multi-micro-via-hole arrays for filtering or for forming clog-resistant aerosol nozzles.

The method of making involves depositing (e.g., electroplating, sputtering, plasma spraying) the interlayer on a mating surface of either the sputter target or backing plate and pressing, such as hot isostatically pressing, the sputter target and backing plate together along mating surfaces so as to form a diffusion bonded sputter target assembly.

Abstract: A flexible plating method by continuously controlling the hydrogen concentration of the plating bath by adding controlled amounts of hydrogen gas. The control of the hydrogen concentration is provided by selected distribution and number of nozzles and size of orifices; and predetermined pressure and duration of hydrogen gas flowing through the nozzles, wherein pressure and duration may be variable with time. The control of the hydrogen concentration is selected to provide a ramp-up phase, needed for a rapid plating start, followed by a saturation phase, for consistent plating stability. With metal layer plating under control, a robust, reliable and low-cost metal structure enabling electrical wire connections to the interconnecting copper metallization of ICs is formed. The structure comprises a layer of barrier metal, preferably nickel, that resists copper diffusion, deposited on the non-oxidized copper surface.
