  • Patent number: 5217273
    Abstract: A battery-powered portable tool for handling electronic workpieces, such as semiconductor wafers, wherein a desired pressure differential is generated by a serial connection of vacuum pumps. The tool includes a number of features which minimize the generation of particulate matter. The pumps are sealed in an airtight chamber to prevent the release of particles created during operation of the pumps. The tool is exhausted directly to the ambient atmosphere to prevent pump exhaust from disturbing particles within the tool. The valve is designed to provide a quick release of even lightweight workpieces and to minimize the sliding of valve components against each other. Submicron filtering removes any particles from the pump exhaust.

    Abstract: A hand operated tool for terminating the conductors of a hybrid cable to insulation displacement contacts contained in a connector. The tool includes a ratchet actuated cam which drives a ram and presser plate toward an abutting member upon which the connector assembly is secured. Free ends of the abutting member pass through the connector housing to provide adequate support. The free ends are then structurally supported by a bar that can be latched in place during operation of the tool. An interlock precludes operation of the tool without the support bar being in place. The operable handle which drives the ratchet is automatically disengaged when the ram has advanced to its fullest. A release mechanism provides for return of the ram to its starting position.

A manually operated piston operates to force a DIP circuit which is properly oriented to the socket, into the appropriate location with the leads from the circuit placed in proper engagement with a printed circuit board socket. Operation of the piston also in addition to properly placing the circuit, also automatically disengages the tool from the circuit after placement has been effected.

  • Patent number: 4866838
    Abstract: A tool for inserting and removing a component, such as a programmable gate array integrated circuit (PGA IC) chip. At least two blocks are mounted on a threaded rotatable shaft, the shaft for causing relative movement between the blocks when rotated. Resilient flanges which are biased outward are attached at one of their ends to the uppermost block, while rigid support flanges are attached to a lower block. The free ends of the resilient flanges contain catches for gripping a PGA IC or its socket (mounted on a printed circuit board, e.g.). For removal of the chip, the catches grip the IC, and the shaft is rotated to cause the IC to be pulled from the socket. For insertion, the catches grip the socket, and shaft rotation causes the lowest block to push the IC into the socket.

  • Patent number: 4852925
    Abstract: A lamp replacement tool which provides for positively captivating lamps for ease of removing or inserting lamps from or into the type of a lamp housing that forms part of a flush mounted push button switch used in aircraft cockpit control panels. The lamp is mounted behind a display legend formed on the face of the push button and for lamp replacement the push button portion of the switch unplugs from the switch body and hinges down to expose the rear of the lamp. A friction fit maintains the lamp in the lamp housing. The lamp replacement tool includes upper and lower blades extending from a handle member in spaced apart parallel relationship. The lower blade is formed with a forked end portion having a u-shape for engaging with a flange formed on a base portion of the lamp and for embracing the base portion. The upper blade is formed with either a v-shaped portion or an aperture for engaging with a base contact protruding from one end of the lamp. The upper blade terminates in an angled lead-in.

  • Patent number: 4847990
    Abstract: A component insertion tool having an electric motor which is connected to a drive shaft having an orbitally vibrating head. The component is placed in the head and positioned over the correct location on a printed circuit board. The tool is turned on and the head orbitally moves the component slightly as the component and tool are pressed toward the circuit board to insert the component properly in the board. A spring allows the head to retract while the component is pressed into contract with the board.

  • Patent number: 4800647
    Abstract: A Pin Grid Array (PGA) insertion tool includes first and second sets of moveably mounted facing fingers which are inserted in the space between a PGA connector and the substrate to which the connector is secured. A plunger includes a PGA insertion member slideably secured to the fingers. The fingers force the insertion member to align parallel to the plane of the connector to preclude tilting of the PGA during insertion. A guide shaft secured to the fingers guides the insertion member during insertion.

  • Patent number: 4785530
    Abstract: A hand tool for assisting in the manual closure of integrated circuit (IC) storage and shipping cartridges, includes a base and a shank extending normal from one end of the base and terminating at a grip or stop formation. A pair of tines extends normal from another end of the base, along a direction of the shank. A hinged flap is mounted next to the second end such that it is rotatable to assume a position spaced parallel and extending along the tines. In use, the tines are inserted into an open end of a cartridge full of ICs, with the shank lying along the outer edge of the cartridge and thereafter pressure is manually applied via the tines against an IC to clear a pair of holes in the cartridge and permit insertion of a closure pin through the holes and between the tines. The flap is positioned against the pin to assist in driving the pin into an interference fit. After the pin is inserted the ICs are firmly retained in the cartridge in the well known and desired manner.

  • Patent number: 4747209
    Abstract: A tool for aligning contacts of an electrical connector with conductive areas of a circuit board comprises a base member with comb means movably secured thereto. The comb means are movable between a first position and a second position to cooperate with the contacts of the connector to insure that the contacts are precisely aligned as the circuit board is inserted into the connector. Securing and alignment means are provided to allow the comb means to easily adjust to the contacts of individual connectors. As the comb means is brought into engagement with the contacts a space bar is provided to prevent the contacts from entering the recess into which the circuit board enters. The contacts are maintained in position as soldering occurs, ensuring that a positive electrical connection is affected.
