  • Patent number: 11759875
    Abstract: Embodiments of the present invention provides an approach for repairing defects in a structure, located in difficult to reach area, by using a self-guiding and self-melting robotic thread. The approach can use an external guidance system to find the target location of the structure and deploy a robotic thread to the defective area. Portion of the robotic thread contains a filler material can have similar materials to the structure. After the system has determined the size, length and volume of the repair, the system calculates the required length of the robotic thread and guides the thread to the defective area. Once the robotic thread is in place, the filler material begins to melt via heat. The filler material, in a melted and pliable state, can flow into the defect area. Once cooled, the filler material can now support the structure.

  • Publication number: 20090266811
    Abstract: A soldering apparatus has a sealable container which accommodates a circuit board therein, weights disposed immediately upon semiconductor devices to press the semiconductor devices toward the circuit board, and high-frequency heating coils causing the weight to generate heat due to electromagnetic induction. The high-frequency heating coils are disposed away from the weights. The heat generated in each weight is applied to a plurality of joint sites of the circuit board, thereby soldering the semiconductor devices to the joint sites. As a result, efficient heating is realized while simplifying the configuration of the apparatus.

  • Publication number: 20090236328
    Abstract: A soldering apparatus for connecting solar cells includes an induction heat source to connect cell conducting tracks, provided with soldering medium, with electric conductors. The heat source has a high-frequency generator and an inductor loop in which the flow of a high-frequency current causes a high-frequency magnetic field to induce in the conducting track and in the electric conductor arranged along the conducting track eddy currents that generate the heat that is necessary for the soldering operation. The U-shaped inductor loop has narrowings and widenings that serve to optimize the heat development in the soldering zone and thus also save energy. Each widening affords access to the soldering point for a magnetic-field-neutral pressure foot that presses the conductor onto the conducting track. The inductor loop extends the entire length of the conducting track of the cell upper and lower sides to solder to the conductor in one soldering operation.

  • Patent number: 7491916
    Abstract: A portable induction tool is provided for soldering or brazing sections of metal pipe together. A work coil head (with induction coil) is U-shaped, allowing placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made. In one form, the tool uses heat pipes to remove thermal energy from the head, and also a heat exchanger for higher-powered units. Power capacitors are generally included with the induction (work) coil to create a tank circuit of a resonant frequency. The induction coil uses Litz wire, copper tubing, or heat pipes with a conductive outer skin to carry the high-current being delivered to the induction coil. The induction coil has a general racetrack configuration, which is typically wound in a U-shape (or as a semicircle) as a single winding, with multiple turns.

  • Publication number: 20080272112
    Abstract: To hard-solder parts to be joined along a common joint, the parts are heated by a heat source e.g. a laser beam (3). Melted solder (7) that is stored in a container (6) is then introduced into the joint. Joints can be filled with solder in this manner at higher speed and the solidified solder surface is practically devoid of pores, thus permitting the priming or painting of said parts without the need for subsequent treatment.

  • Patent number: 7009157
    Abstract: Procedure for soldering the constituent layers of a multilayer printed circuit and machine for performing it. The procedure is applicable to circuits made up of layers containing the circuit image (2, 3, 4, 5,) that have perimetral strips (9) including reserve areas (11), superimposed and separated from each other by isolating layers (6, 7 and 8). The procedure includes the following steps: i) place a heater circuit (13) composed of a flat winding with at least one turn in short-circuit (14) in each reserve area (11); ii) superimpose the layers that contain the circuit image (2, 3, 4, 5,) and the isolating layers (6, 7 and 8) in alternating order; iii) secure the position of the layers relative to the others, thereby creating groups (12) of reserve areas (11); iv) place induction electrodes (18) over the groups (12) of reserve areas; v) soldering each one of the groups (12) by application of a magnetic field of variable induction.

  • Patent number: 6799712
    Abstract: A system is disclosed for determining optimal process settings for a conveyor oven, such as a reflow oven used to reflow solder paste on a PCB assembly. According to a disclosed embodiment, an ideal temperature profile is obtained from the solder paste specifications of the solder paste to be reflowed in the oven. The ideal temperature profile of the paste includes a preheat phase, a soak phase, a reflow phase and a cooling phase. One or more profiles that fit the oven are obtained by aligning the beginning of each phase of the ideal profile with a forward end of an oven zone. The profile that best fits the oven is selected as a target profile for the reflow soldering process. The set points of the oven zones for effecting the target profile when the solder paste is conveyed through the oven are determined.

  • Patent number: 6548790
    Abstract: A novel apparatus for manufacturing Solid-Solder-Deposit Printed Circuit Boards (SSD-PCBs) by melting solder powder via induction heating consequently forming relatively thick layers of solid solder over the soldering pads of a bare-PCB 230. Solid Solder Deposit (SSD) refers to a relatively thick layer of solid solder metallurgically bonded over the soldering pads of a bare-PCB 230 such as that said SSD-PCB by itself is the source for solder alloy during a subsequent soldering operation. The manufacture of SSD-PCBs provides the electronic assembly industry with ready-to-solder PCBs consequently eliminates the need to use solder paste at the assembly floor. This invention, unlike the prior art for producing SSD-PCBs, utilizes a solder powder pile 232 that is melted by localized electromagnetic induction heating.
