    Abstract: A principle of surface interlocking wherein the imperfections of two parallel surfaces deform and interlock under pressure. The surface interlocking enables the combination of a bridging element and a bonding tip of a diffusion bonding apparatus to pick up, transport, position at a unique location, and bond the bridging element in place to the conductors or pads. In the invention a single point bonding tip as part of a bonding apparatus is used to pick up the, to be, bridging metal object transport it to the bonding site and perform the entire bridging bonding operation all in one sequence of steps.

    Abstract: A method for bonding together at least two conductive members 20, wherein each member includes at least one metallic 22 having a respective bonding area 24. At least one member has a deposition of metallic bonding material 26 attached to each respective conductor proximate each bonding area, and at least one member has a plastic element 28 attached thereto proximate each respective bonding area. The members 20 are positioned in a predetermined orientation, clamped together between an ultrasonic horn and anvil arrangement, with pressure and orthogonal ultrasonic energy being applied thereto so that each plastic element 28 is heated, which in turn melts the bonding material 26. Any plastic element material between the conductors is squeezed away therefrom and the respective conductors 22 are brought into proximity with each other so that a molten joint of bonding material physically contacts each respective conductor. The members are then held together until each joint solidifies, and then the horn and/or anvil are retracted.

    Abstract: A connecting pin of a coil, which has an end section with an end section of a winding wire wound thereon with a plurality of turns, is initially provided with a drop of a fluxless soft solder and then arranged in the vicinity of the points of two opposite electrodes. An arc of a specific strength and duration is struck between the electrodes, so that the soft solder is fused and connects the winding wire to the connecting pin. The result is a fluxless soldering of the winding end in conjunction with low thermal loading of the coil former and of the connecting pin.

    Abstract: An electrical joint is provided between first and second electrical leads having different inner diameters. It comprises an electrically conductive transition post including a disk-shaped a separation member, a first cylindrical mounting post having a first diameter integral with the separation member and extending away therefrom in a first direction, and a second cylindrical mounting post having a second diameter integral with the separation member and extending away therefrom in a second direction generally opposite the first direction. The separation member lies in a plane transverse to the longitudinal axis of the first and second mounting posts and has a diameter greater than that of either the first or the second mounting post. A first electrical lead is fittingly received on the first mounting post and a second electrical lead is fittingly received on the second mounting post. In each instance, the free ends of the electrical leads abut the separation member. Thereupon, the first and second electrical leads are welded to the first and second mounting posts, respectively, such that electrical continuity is achieved between the first and second electrical leads. In another embodiment, each of the first and second mounting posts may have a threaded outer peripheral surface for engageably receiving thereon an associated one of the electrical leads.

    Abstract: A method of repairing an area of metallization that has lifted from a circuit board substrate uses a dry film epoxy placed between the lifted metallization and the substrate. Downward pressure and heat are simultaneously applied to the lifted area to rebond it to the substrate. Both metallization pads and traces may be repaired with the method, and the resulting bond may be stronger than that originally present. When heated, the dry film epoxy will melt and cure very quickly, requiring no further processing. The method is particularly useful when repairing circuit boards intended for microwave circuitry, in which conductive ribbons are gap welded to metallization pads. A metallization pad repair operation may be combined with a ribbon attachment operation, accomplishing both with one gap welding operation. The gap welder provides the downward force and heat necessary to bond the ribbon and repair the lifted pad.
