  • Patent number: 9591795
    Abstract: An apparatus includes at least one grip mechanism of a rework nozzle configured to grip an electrical component that is soldered to a printed circuit board. The apparatus includes at least one spring coupled to at least one grip mechanism, where the spring is configured to move beyond a minimum threshold in response to an initiation of a melt of a solder that attaches the electrical component to the printed circuit board. The apparatus includes at least one sensor coupled to at least one spring, where the sensor is configured to detect the move of at least one spring beyond the minimum threshold. At least one sensor is configured to communicate at least one activate signal in response to detection of the move of one or more springs beyond the minimum threshold.

  • Patent number: 9302277
    Abstract: An apparatus for a component rework nozzle includes a nozzle with a proximal end spaced apart from a distal end along an axis. The proximal end is sized to partially enclose a component during a component rework process. The component is disposed on a substrate by way of a plurality of solder joints. The apparatus includes an indentation defined in a side of the nozzle. The side of the nozzle is parallel to the axis. The indentation is shaped to maintain a separation between the nozzle and a neighboring component. The neighboring component is disposed adjacent to the component on the substrate. The apparatus includes a plurality of notches disposed on the proximal end of the nozzle. The plurality of notches are formed to balance heat distribution, during the component rework process, across the component.

  • Patent number: 9293636
    Abstract: A process for dressing a solder pad removes excess solder from locations that should be free of solder, such as circuit traces, other solder pads, and components near the solder pad being dressed. A first area of a substrate comprises solder to be removed and is heated to a first temperature. A second area of the substrate is heated to a second temperature. A vacuum nozzle is heated to a third temperature sufficient to melt the solder and is scanned across the area to be dressed, melting and vacuuming away the excess solder. The scanning process is controlled using a computer numerical controlled (CNC) machine.

  • Patent number: 6761304
    Abstract: A heating head for soldering and de-soldering surface mount devices (SMD's) using hot inert gas or air is comprised of a handle in which there is placed a heater sub-assembly on which there is secured a quick connect mechanism for mounting a heating nozzle. The heater sub-assembly is enclosed in a shroud and is secured to the end of the handle by a thermal insulating ring, such shroud housing a ceramic rod having elongated bosses on which a heating element is secured, while a laminar flow equilizer is used to provide more uniform gas flow across the heating element. Quick connect mechanism is secured to the heater sub-assembly shroud and uses a spring loaded winged locking mechanism to the secure heating nozzles to the heater head. In one embodiment, the heating nozzles have a truncated pyramid shaped chamber to which individual end nozzles are attached for directing gas flow.

  • Patent number: 6719188
    Abstract: A method and apparatus are provided for reworking electronic component assemblies where the components are joined by solder interconnections. A cutting device employing a heated wire, blade or other cutting element is forced against and through the solder interconnections to sever the interconnections. A preferred cutting device employs moving the cutting element transverse to the solder interconnections to also provide a sawing action to the solder interconnections. Another cutting device employs a water jet to provide a high pressure stream of water that cuts and severs the solder interconnections.

  • Patent number: 6499644
    Abstract: A method and apparatus for desoldering electronic components from a substrate. A vacuum is used to enhance the flow of a hot gas under an electronic component to reflow the solder connections attaching the electronic component to a substrate. Water vapor is added to the hot gas to increase the heat capacity of the hot gas. A system for periodically changing the direction of flow of the hot gas and vacuum under the electronic component is used to uniformly heat the solder connections. A method and apparatus for depositing underfill material between an electronic component and the substrate on which the electronic component is mounted. A vacuum is applied to enhance the flow of underfill material into the space between the electronic component and the substrate.

  • Patent number: 6457628
    Abstract: A safety switch device for a gas jet soldering gun includes a ignition push button having an outer periphery provided with a locking drive block, a housing having an inner wall defining an L-shaped drive slot mating with the locking drive block, and a spring mounted in the ignition push button for providing an axial thrust and a rotational torque. In such a manner, the user has to rotate the ignition push button to a proper position so that the ignition push button can be pressed to drive the igniter to ignite the fire, thereby preventing a child from freely opening the gas jet soldering gun.

  • Patent number: 6237831
    Abstract: A disposable solder receiving capsule for a hand held vacuum solder extracting desoldering tool is formed of an outer tube which is closed at one end by a porous filter and has an opening at its opposite end, and a hollow solder collection chamber part, having a tubular member with an open end and which is closed with respect to the passage of solder therethrough at an opposite end, forming a solder receiving space within it. The solder collection chamber part is concentrically positioned within the outer tube with an air plenum disposed between the closed end of the chamber part and the filter and with at least one air channel extending the length of solder collection part for providing a path for gases entering the open end of the outer tube to the plenum and the filter that is separated from the solder receiving space. For facilitating solder reclamation, the capsule can be formed entirely of materials which are shape-sustaining when exposed to a temperature of 400° F.
