  • Patent number: 4943000
    Abstract: A method is disclosed for brazing without filler metal two components, of which at least one is an Al alloy. According to the method, prior to brazing, at least one Al alloy component is maintained in a region of temperatures included between the temperature of solvus T.sub.v of the alloy and 2/5 of temperature of fusion (solidus) T.sub.s of the alloy, expressed in degrees Kelvin, for a sufficient period of time. After this treatment, which may or may not be isothermal, the alloy is suitable for brazing in a domain of temperatures included between the temperature of fusion T.sub.e of the most fusible eutectic corresponding to the equilibrium diagram of the constituents of the alloy, and that of the solidus of the alloy. The method permits the realization of perfectly homogeneous brazed seams for alloys considered not to be brazable.

  • Patent number: 4884737
    Abstract: Two or more ceramic bodies are bonded together by oxidizing with a vapor-phase oxidant molten metal obtained from a body of precursor metal to form an oxidation reaction product bond. The oxidation reaction product is formed between adjacent facing, substantially congruent surfaces of the ceramic bodies and bridges the surfaces, thus bonding the ceramic bodies to each other. Promoters may optionally be used to facilitate formation of the oxidation reaction product.

  • Patent number: 4878609
    Abstract: An apparatus for manual wire bonding, comprising an ultrasonically energizable and/or thermocompression wedge (11) for pressing the wire (34) against a bonding pad, wherein the wedge (11) is part of a bonding head (10) adapted to be moved towards and away from said bonding pad, especially in up/down direction. The bonding pad is disposed on a base which is movable in a direction approximately transversely to the direction of movement of the bonding head (10) for positioning the bonding pad opposite said wedge (11). Furthermore, means is provided for controlling the drive unit (20) of the bonding head. Preferably, the drive unit (20) for the bonding head motion is a d.c. servomotor, wherein each part-motion and non-motion of the bonding head (10) can be adjusted individually in respect of travelling distance and speed and motionless period, respectively, and can be checked as to execution. To this end the drive unit (20) cooperates with a distance and speed control (44-51) and feedback (28) unit.

  • Patent number: 4875618
    Abstract: The invention relates to joining of fine wires, and more particularly to a wire bonding method suitable for connecting a number of wires within a narrow area. A first wire is bonded on a pad, and a second wire is bonded on the position where the first wire has been bonded. Bonding of a subsequent wire is performed in that the wire is stacked and bonded in similar manner mentioned above. Thus a plurality of repair wires can be bonded within one pad even if the pad area is very small.

  • Patent number: 4873781
    Abstract: AN artificial fishing lure having hidden hooks recessed within the body thereof to prevent snagging on weeds, rocks or the like when the lure is moved through the water. A trigger is provided and is attached at one end to a fishing line, and at a second end to a spring hook assembly. The spring hook assembly is formed from a single wire member, and has a medially positioned bite portion engaging said trigger assembly, and opposed ends respectively terminating in hook arms and hook ends. Snapping the fishing line activates the trigger assembly, which in turn activates the spring hook assembly, causing the hook arms to extend outwardly from the body of the fishing lure through longitudinal slits therein.

  • Patent number: 4860941
    Abstract: An improved method is described for ball bonding an aluminum wire to a contact pad of a microelectric device. In ball bonding, the wire is fed through and protrudes from a capillary hole in a bonding head, an electric arc melts the protruding wire into a ball, the solid ball thus formed is pressed and flattened onto the contact pad by the bonding head and the ball-contact surface interface is subjected to ultrasonic vibrations to form a bond between the flattened ball and the contact pad. Aluminum wire has presented a problem in forming asymmetric, porous, faceted balls that ball-bond very poorly. By using an aluminum wire coated with an electrically insulating layer that melts above the melting temperature of aluminum and has an electrical resistance sufficient to prevent the electric arc from shifting up the wire and away from the tip, the problem of poor quality balls is solved and a round, axisymmetric ball is formed which ball-bonds consistently well.

  • Patent number: 4858820
    Abstract: A technique is provided for desoldering circuit components employing a desoldering aid that fits like a cap on a standard size rectangular circuit component. The aid has a rectangular top of high thermal conductivity metal substantially the same size as the circuit component. At least a pair of integral sides along opposite edges of the top are bent normal to the top and are not further apart than the outside of the electrical leads on the opposite sides of the circuit component for good thermal contact therewith. The depth of the inside of the box is greater than the height of the top of the component so that there is no contact between the top of the box and the top of the component. The top of the box over the component is heated sufficiently to melt solder on the electrical leads. The box and component can then be lifted together from the printed circuit board.

  • Patent number: 4850132
    Abstract: A device for fishing with a dead or live minnow includes a gorge engaging member formed with outwardly extending projections. In use, the member is inserted into the minnow's mouth and secured to a fishing line by means of an eyelet portion formed in a forward end of the member. Pulling force acting upon the fishing rig during trolling, casting, or jigging acts to partially embed the projections within the minnow's mouth to resist withdrawal therefrom. One or more fish hooks may be secured to the eyelet portion for subsequent attachment to the minnow proximate the dorsal fin and/or tail.

  • Patent number: RE33197
    Abstract: Wave soldering process and apparatus for the soldering of elements such as, for example, printed circuit assemblies with surface mounted components and the like which yield improved soldering results by promoting the penetration of solder into narrow spaces between components, the filling of small holes in a board, filling crevices, filling corners adjacent to solder masks and all other areas where solder wetting is difficult to achieve with conventional machines. The process provides the steps of moving an element in a predetermined path, forming a solder wave beneath the path so that at least a portion of the element passes through the solder wave, and producing an oscillation in the solder wave during the passage of the element therethrough.
