Patent number: 6266877Abstract: An electronic isolation shield mounts on a circuit board, around an electronic component to provide a minimum amount of shielding over a set period of time. The shield has a body made from a shielding material that is sized and shaped to fit around and cover the electronic component. The body has a sealing edge that is adapted to contact an upper surface of the circuit board and surround the electronic component. Resilient downwardly projecting tabs are attached to the body and each includes a securing end that extends past the sealing edge. The tab is securable to the circuit board along a securing axis. The sealing edge of the body is forced into sealing engagement with the upper surface of circuit board. The tab is laterally displaced with respect to the securing axis continuously over the set period of time so that the sealing edge is forced into the circuit board sufficiently to provide the minimum amount of shielding to the electronic component over the set period of time.Type: GrantFiled: February 8, 1999Date of Patent: July 31, 2001Assignee: Lucent Technologies, Inc.Inventors: Joseph A.

Patent number: 6266870Abstract: The invention is directed to a wire cutting and stripping and terminal attaching apparatus and, in particular to an improved wire positioning mechanism for positioning the stripped end of an insulated wire in an open barrel terminal. After the insulated wire is cut and a slug of insulation is removed from the end of the wire, a gripper rotates the wire so that the bare or stripped end of the wire is located above an open barrel terminal supported on a lower die of a terminal attaching unit. An upper die is movable on the terminal attaching unit in a direction toward and away from the lower die to crimp the terminal on the stripped end of the wire. The wire positioning mechanism includes a positioning member which is mounted on the upper die and arranged to contact the gripper and push the stripped end of the wire downwardly into the open barrel terminal before the upper die operates to crimp the terminal.Type: GrantFiled: September 15, 1999Date of Patent: July 31, 2001Assignee: Autos Engineering Co.Inventors: Kenneth A.

Patent number: 6256866Abstract: A method of manufacturing a printed circuit board with a polymer thick-film (PTF) resistor whose dimensions can be defined with improved precision by providing a circuit board construction having a planar surface where the resistor is to be deposited. To achieve the desired board construction, the interconnect for the resistor is pattern plated using a permanent photodielectric layer as a plating mask instead of a sacrificial plating resist. The interconnect can be patterned before or after the PTF resistor ink is printed. The x and z dimensions (width and thickness, respectively) of the resistor are determined by the deposition process, while the y dimension (electrical length) is accurately determined by copper terminations.Type: GrantFiled: May 11, 1999Date of Patent: July 10, 2001Assignee: Motorola, Inc.Inventor: Gregory Dunn
