摘要： A system for reducing the number of points to be tested on a dual sided printed circuit board. The circuit board includes a top and a bottom surface and a plurality of network traces extending across both sides of the printed circuit board. Each network trace includes end points. The system provides for identifying the end points of a network trace extending on both sides of the printed circuit board. The mid-point along the network trace which is common to both sides of the printed circuit board is identified. Structure is provided for independently testing each side of the printed circuit board between one end point and the mid-point on the top surface of the printed circuit board and between the mid-point and the second end point on the bottom surface of the printed circuit board.

摘要： A system for reducing the number of points to be tested on a printed circuit board where the printed circuit board includes a plurality of network traces each having end points and a plurality of pads provides for the identification of the end points of each network trace of the plurality of network traces. Certain ones of the plurality of network traces network located within a predetermined distance of one another are grouped to form a plurality of groups of network traces. The identified end points of the grouped network traces are connected together within each group of network traces to form a continuous trace having one pair of end points for each group of network traces. The end points are used for testing the printed circuit board.

摘要： A method for verification of components installed on a printed circuit board includes the step of capturing an image of an entire printed circuit board and components mounted thereon using a scanning device. After it has been determined that a printed circuit board having no defects, the scanned image of the circuit board has no defects is stored in a memory. The image of the entire printed circuit board under test, and having potential defects is then captured using a scanning device. The image of the printed circuit board under test is then stored in a memory. The stored image of the printed circuit board having no defects is then overlaid in registration with the stored image of the printed circuit board with potential defects on a display in alternating sequence in order to visually provide an indication of a defective component or defective component placement on the printed circuit board under test to an operator.

摘要： A multiplicity of integrated circuit connector contact sockets mounted to a plurality of carrier strips are moved between pairs of orientation rollers with tails of the contacts protruding upwardly whereby an upper socket portion of one contact is aligned with an upper socket portion of a contact on a carrier strip in an adjacent row. A plurality of integrated circuit connector insulators having socket receiving apertures formed therein are held together in an array and placed over the contact tails with one tail being received within each aperture of an insulator. The carrier strips are simultaneously advanced beneath a work station wherein a tool presses the insulators downwardly to tightly fit the contact socket portions into the receiving apertures in the insulators. A shearing tool then severs the insulators in the array from one another except for the continued affixation of the contact sockets to the parallel carrier strips. The carrier strips are then moved through a stripping station comprising a block having parallel channels for receiving the carrier strips and a flat inclined upper surface wherein the carrier strips are restrained from vertical movement while the inclined ramp strips the insulator mounted contacts from the carrier strips to form completed individual connectors.

An arcuate door section has a door member portion that mates with the base member extending portion that may include locking means to prevent the dome shelter from collapsing. All of the arcuate sections terminate in end portions provided with an aperture proximate the distal ends thereof. A pair of bolts, one of which is placed through one of the apertures provided on the sections, locks the units together in a nesting manner and a second bolt locks the other apertures provided on the section members. Each of the sections nest within another section when the unit is completely extended and collapse to essentially the width of the roof section.

摘要： A wire stringing apparatus interconnects terminals of electronic components mounted upon a circuit board. A wire stringing head, which is transported on an x-y mechanism driven by a controller, wraps an insulated wire about terminals and guide pins mounted on the circuit board. The insulated wire is connected throughout the circuitry to form all of the necessary interconnections. After the wire is installed an automatic solder feeding mechanism and a heating element are transported over the circuit board to selectively solder the interconnecting wire to the appropriate component terminals. The heat generated for the soldering procedure additionally removes the insulation from the interconnecting wire at the connection terminal. A cutting tool transported over the circuit board severs the interconnecting wire at selected points to form individual conduction paths between circuit terminals. During the stringing and soldering procedures, error checking mechanisms insure that the insulation on the interconnecting wire has not been broken, that the stringing head has not missed a guide or pin, and that the soldering apparatus has produced a reliable solder connection.
