Patent number: 7491916Abstract: 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placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made.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.Type: GrantFiled: January 31, 2007Date of Patent: February 17, 2009Assignee: Nexicor LLCInventors: John P. Barber, Robert C. Cravens, II, Antonios Challita, Susan A. Stanton

Publication number: 20080272112Abstract: 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.Type: ApplicationFiled: May 20, 2005Publication date: November 6, 2008Applicant: Soutec Soudronic AGInventor: Werner Urech

Patent number: 7009157Abstract: 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.Type: GrantFiled: May 27, 2002Date of Patent: March 7, 2006Assignee: Chemplate MaterialsInventor: Victor Lazaro Gallego

Patent number: 6799712Abstract: 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.Type: GrantFiled: January 9, 2002Date of Patent: October 5, 2004Assignee: Electronic Controls Design, Inc.Inventors: Paul M.

Patent number: 6548790Abstract: 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.Type: GrantFiled: October 30, 2000Date of Patent: April 15, 2003Inventor: Horacio Andrés Trucco
