  • Patent number: 5603857
    Abstract: An apparatus for removing and/or replacing a surface-mounted integrated circuit that includes electrical heating elements disposed in a planar rectangular array and a handle positioning the element array in heat-conductive contact with the legs on the side edges of a surface-mounted integrated circuit. When electrical energy is applied to the heating elements, the elements and the integrated circuit legs are heated so as to liquify the solder joints between the legs and the circuit board pads. An air pad is positioned within the heating element array for grasping and holding the integrated circuit to facilitate lifting of the circuit from the circuit board, or for holding a replacement integrated circuit on the circuit board, when all of the solder joints have been liquified.

  • Patent number: 5533430
    Abstract: An archery target having a threaded bore directed medially thereof, with the archery target having a first density and an insert threadedly received within the target, having a second density at variance relative to the first density. An apparatus for effecting the cutting of a helical groove within the target block, such that a support yoke mounts an electrical heated resistance wire having a loop directed into the wire, whereupon rotation of the wire loop within a target block bore effects axial displacement of the cutting wire relative to the bore of the target block to impart a groove into the bore of helical configuration to threadedly receive the insert within the bore.

  • Patent number: 5345059
    Abstract: An electrically-heated spoon including a flat heating device made of a plate-like positive temperature coefficient (PTC) resistor having a periphery side wall of the spoon mounted to the periphery and a handle of the spoon extending from the side wall. A pair of conductive wires in electrical connection with the heating device are embedded in the handle and extend out of a remote end of the handle to define an external connector for connection to an external power source. The plate-like positive temperature coefficient resistor is sandwiched between two insulating plates and then encased by two opposite metal casing members with the conductive wires, which are connected to the resistor, extending through openings formed on the casing members for connection to a power source.

  • Patent number: 5278393
    Abstract: A specialized desoldering unit head is provided for the limited purpose of removing high-density solid state electronic components from circuit boards in a single step, without damaging the circuit board. In the typical case of a four-sided component with a row of leads on each side, the unit includes an electrically heated head which fits over the component with a heat-conducting blade fitting over each of the rows on the four sides of the component. The head has depth limiters stop means formed by at least one adjustable screw threaded through at least one laterally extended cross-strap on the head and positioned to engage against the top of the component to limit the lowering of the heated blades relative to the rows of leads so that the heated blades do not touch the circuit board, or even the horizontal portion of the surface-mounted leads of the lead rows, but only mounds of solder which have been applied over the leads to facilitate their heating and the removal of the component.

  • Patent number: 5252806
    Abstract: A carpet iron adapter plate of the type primarily intended for attachment to the sole plate of a carpet iron for extending the working surface of the iron so that wider carpet tape can be used. The adapter plate comprises a base having a top surface and a bottom surface, the top surface has a recessed portion formed therein that is configured to receive at least a portion of the sole plate of the carpet iron therein. The adapter plate has at least two arms attached to the top surface of the base, each arm having first and second ends. The first end of one of the arms is attached proximal to one edge of the base and the first end of another one of the arms is attached proximal to an opposing edge of the base.

  • Patent number: 5229575
    Abstract: A thermode having a relatively long and thick blade composed of a high thermal conductivity, low thermal expansion material, e.g., molybdenum, provides an elongated contact surface for bonding a row of leads of an electronic component to a circuit board. A thermode holder is coupled to the blade by means of a plurality of struts, including a pair of outer struts, each connected at one end of the respective ends of the blade and at an acute angle facing the other outer strut, and a pair of shorter inner struts, each connected with the blade intermediate the ends of the blade and at an acute angle facing the outer strut adjacent thereof, such that in response to a force urging the blade against the circuit board, the outer struts cause a negative deflection of the blade with respect to the board and the inner struts decrease the magnitude of the deflection. The blade is heated by electric current supplied thereto from a transformer through the inner and outer struts.

  • Patent number: 5210394
    Abstract: A smokeless carpet seaming iron for melting an adhesive on a carpet tape wherein non-contaminated air is discharged into the ambient from the seamer includes a housing which contains a vent outlet and an open bottom. First and second filters are disposed internally of said housing and are accessible externally of said housing for removal and replacement. An electrically heated sole plate is disposed internally of said housing for creating heat at said open bottom of said housing. And a motor and a fan with filters are disposed internally of said housing between the first and second filters for creating a suction within said housing drawing smoke and fumes created during the carpet seaming operation through the open bottom into the housing for filtration by the first and second filters before discharge through a vent head to the ambient atmosphere.

  • Patent number: 5201450
    Abstract: A heat block of a wire bonding machine including an inner lead heating part for bonding each one end of wires to each inner lead of a lead frame, a chip heating part for bonding the other ends of the wires to a semiconductor chip, and a differentially heating member for heating the inner lead heating part of the heat block at a relatively higher temperature than that of the chip heating part of the heat block. The heat block of this invention provides advantage in that the chip heating part is heated at a proper heating temperature, at which temperature the semiconductor chip is not injured, while the inner lead heating part is heated at a relatively higher temperature than that of the chip heating part, thereby considerably improving the bonding effect at the bonding portions between the wires and the inner leads of the lead frame owing to the relatively higher heating temperature of the inner lead heating part than that of the chip heating part.
