  • Patent number: 6796484
    Abstract: A brazing product, e.g. a brazing sheet product, having an aluminium layer made of an aluminium alloy comprising silicon in an amount in the range of 2 to 18 weight %, and a layer comprising nickel on the outer surface of the aluminium layer such that taken together the aluminium layer and all layers exterior thereto form the filler metal for a brazing operation. The filler metal has a composition containing at least one element: (i) with a smaller exchange current density for the Hydrogen Evolution Reaction (“HER”) than nickel and/or (ii) such that the electro-chemical potential difference between particles of Ni-aluminide(s) of the filler and the aluminium alloy matrix of the filler is reduced. The filler metal's mol-ratio of Ni to such element(s) is in the range of 10:(0.3-30). The invention also relates to a method of manufacturing a brazed assembly using the brazing product, and to a brazed assembly comprising at least one component made of the brazing product.

  • Patent number: 6794025
    Abstract: The inventive method for producing packaging materials consisting of a polyolefin foam layer (B) coated with a coating film (A) on at least one side, which packaging material is formable into self supporting packaging items, such as trays, by thermoforming or folding, comprises a coextrusion step or an extrusion lamination step in which step the bonding between the polyolefin foam layer (B) and the coating is achieved. With the extrusion lamination step, the method is as follows: In a first method step, a single-layer or multi-layer coating film (A) is produced by extrusion or coextrusion, in a second method step a polyolefin foam sheet (B) is produced by expansion and extrusion and in the third method step the polyolefin foam sheet (B) is coated with the coating film (A) by extrusion lamination, wherein a polyolefin bonding layer (30) is extruded between the foam sheet (B) and the coating film (A) and pressure is applied to the combination.

  • Patent number: 6793116
    Abstract: A solder ball achieves a desired quantity of solder material for a solder joint easily without increasing the thickness of a solder layer formed to cover a core. The solder ball comprises a conductive core having depressions on its outer surface, and a solder layer formed to cover the outer surface of the core in such a way as to fill the depressions of the core. Thus, the quantity of the solder material included in the ball is supplemented by the solder material filled into the depressions. Preferably, the core has a higher melting point than the solder layer and wettability to the solder layer. The core may have a cavity in its inside, thereby forming a shell-shaped core. The core may be made of a porous metal body having pores, in which part of the pores reaches the outer surface of the core, thereby forming the depressions.

  • Patent number: 6783057
    Abstract: The object of this invention is to employ a solder alloy comprising tin/lead/silver in order to provide a wider solidification range and achieve balance between the surface tensions of both side of a small leadless component. The expanded solidification range slows the melting and wetting time so as to balance the surface tension of the molten solder, and in turn reduces the tombstoning frequency. The preferred Ag concentration is 0.2-0.5% in weight, the more preferred Ag concentration is 0.3-0.4% in weight. For reflow soldering of small leadless components, the pastes made with the alloy compositions of Sn62.6Pb37Ag0.4 and Sn63Pb36.6Ag0.4 results in improvements in tombstoning.

  • Patent number: 6779706
    Abstract: Abutted portions of face plates 12b and 22b of frame members 10 and 20 are friction stir welded. With the abutting, a projecting portion 20c of an end portion of the face plate 20b of the frame member 20 is inserted into a recessed portion 12c of an end portion of the face plate 12b of the frame member 10. By this engagement, the outer face on one face side of the face plates 12b and 20b form a smooth surface, so that there is no step at the joined edges. Next, a rotary tool 250 is inserted into the gap between the abutted plates, from the side of the raised portions 16 and 26 of the face plates 12b and 20b, while the other faces 12bc and 20bc of the face plates 12b and 20b are supported flatly on a bed during the friction stir welding. Accordingly, the welding of the engaged plates can be carried out without any step-wise difference.

  • Patent number: 6780806
    Abstract: The invention provides new methods for separating nitrogen from a mixture. The invention provides adsorbents specifically for accomplishing nitrogen separation. The adsorbents and separation methods are particularly useful for the selective adsorption of nitrogen from air. In one aspect, the adsorbent comprises an ion exchange zeolite X and preferably zeolite LSX (low silica zeolite X). The zeolite is most preferably a lithium-based zeolite. Further, the zeolite has exchangeable cationic sites, with silver cation or copper cation occupying at least some of the exchangeable cationic sites. The Ag/Cu exchanged zeolite is heat-treated under specific conditions as per the invention. The presence of the silver cation or copper cation at any of the sites will provide an improvement over the non-exchanged zeolite.

  • Patent number: 6761305
    Abstract: A honeycomb structure with a plurality of flexible material strips which are arranged next to one another and are connected to one another is presented. The material strips have a corrugated shape with U-shaped cross section of essentially straight, vertical partial areas (3) and curved, horizontal partial areas (2). The material strips are connected to one another at contact points (4) of the straight, vertical partial areas. In addition, a device for manufacturing a honeycomb has welding sections (6). The flexible material strips (9) are guided by the welding sections (6), where the material strips are welded to one another by means of a comb-like finger system (10). The finger system or the welding sections are laterally displaced by two sections and by a pressing operation taking place between the finger and the welding section. This presses two material strips onto a heated welding wire (7), which leads to the thermal connection of the material strips.

  • Patent number: 6755339
    Abstract: A fluxer applies powdered flux to an object. The fluxer includes an enclosure that defines a chamber where the object is fluxed. The enclosure includes an inlet for receiving the object into the chamber prior to application of the flux and an outlet for discharging the object from the chamber after the flux has been applied. A conveyor extends through the enclosure for traversing the object into and out of the chamber. The fluxer also includes a hopper for storing the flux and an applicator in fluid communication with the hopper for applying the flux to the object. A flux recovery system is in fluid communication with the chamber to introduce and maintain a negative pressure within the chamber. As a result, excess flux is retained within the enclosure. This excess flux can then be recovered and recycled to the hopper.

  • Patent number: 6747243
    Abstract: A method and cluster tool for selectively removing contaminating particles from a substrate surface using a laser. An inspection tool scans the substrate surface to detect and identify any defects on the substrate surface, and then suitable software analyzes the scanned data to determine characteristics of the defect including the type of defect, the number of defects, sizes of each defect and the planar x, y coordinates of each defect. This data is used to command a laser tool to remove only those defects identified as contaminants that are capable of being removed from the surface of the substrate and may be detrimental to subsequent substrate processing techniques. The laser contacts this identified contaminant at its x, y coordinates to remove only such contaminant while not substantially treating or directly contacting the area surrounding the contaminant, thereby preventing damaging or altering the substrate surface.
