  • Patent number: 6177728
    Abstract: CTE differentials between chips and organic dielectric carriers, boards or other substrates to which the chips are attached are accommodated with a layer of a thermoplastic material, preferably a thermotropic polymer whose physical properties can be altered by extrusion or other physical processes, such as liquid crystalline polyesters, that modifies the thermal expansion of at least one component of the package and thereby reduces CTE differentials. The material may be applied to the entire surface of a chip carrier, printed circuit or other substrate, or form an interior layer of a multi-layered structure. It may also be applied to selected regions or areas on the surface of a carrier or other substrate where adjustment is required.

  • Patent number: 6173358
    Abstract: A computer system for high-performance video and audio manipulations comprising a locked memory cartridge and an audio/video/compact disk (CD) drive controller/coprocessor. The computer system has a central processing unit (CPU) with at least one bus associated therewith, with the bus having at least one bus line. The cartridge comprises a readable memory, a memory control circuit, a lock control circuit, and a connector all in circuit communication with each other. The connector allows the memory, the memory control circuit, and the lock control circuit to be pluggably connected in circuit communication with the CPU. The memory control circuit scrambles some of the bus lines, thereby scrambling the data in the memory on reset, and unscrambles the bus lines responsive to inputs from the lock control circuit.

  • Patent number: 6170078
    Abstract: A system and method for the fault simulation testing of circuits by using a behavioral model is provided. The behavioral model includes a fault bus, decoder, and input and output ports. The decoder decodes mapping fault values, which are applied to the fault bus, to either a no-fault or to a specific fault which is internally encoded into the behavioral model. Accordingly, a single behavioral model can be used to dynamically model a fault-free circuit or machine and one or more faulty circuits or machines based on the mapping fault data applied to each model's fault bus. A fault simulation tool applies test simulation data having mapping fault and test parameter data to at least two identically coded behavioral models (i.e., a fault-free model and a faulty model, as defined by the applied mapping fault data). Output data are generated by each behavioral model and recorded by the fault simulation tool.

  • Patent number: 6156445
    Abstract: The present invention provides an ablatively photodecomposable polymer having a photoabsorber bound to the polymer (the "ablatively photodecomposable polymer") which does not phase separate, nor does it crystallize. The ablatively photodecomposable polymer provides even ablation, high resolution and in preferred embodiments, can withstand potassium permanganate etchant and ferric chloride etchant. The ablatively photodecomposable polymer is strippable, although it can remain on the substrate if desired. The ablatively photodecomposable polymer comprises a polymer to which a photoabsorber is bound, either covalently or ionically. The present invention is also directed to a process for forming a metal pattern on a substrate employing the ablatively photodecomposable polymer.

  • Patent number: 6148700
    Abstract: Window sashes such as double hung sashes often are assembled with a counterbalancing mechanism to facilitate the opening and closing of the window. When the sashes are made from vinyl, the counterbalancing of the window is commonly achieved by the use of a pair of coil springs, one mounted within a channel in the sash on either side of the window. A programmable motorized hand tool is used to apply tension quickly to each of the springs thereby improving production rates and quality control while reducing the risks of repetitive motion injury to the person using the hand tool. A programmable stepper controller drives the motor and controls the functions of the hand tool such as the speed and direction of rotation, the number of revolutions and the start-up and operating torques.

  • Patent number: 6150716
    Abstract: A package for mounting an integrated circuit chip to a circuit board or the like is provided. The package includes a chip carrier which has a metal substrate including first and second opposed faces. A dielectric coating is provided on at least one of the faces, which preferably is less than about 20 microns in thickness, and preferably has a dielectric constant from about 3.5 to about 4.0. Electrical circuitry is disposed on the dielectric coating, said circuitry including chip mounting pads, connection pads and circuit traces connecting the chip mounting pads to the connection pads. An IC chip is mounted by flip chip or wire bonding or adhesive connection on the face of the metal substrate which has the dielectric coating thereon. In any case, the IC chip is electrically connected to the chip mounting pads either by the solder ball or wire bond connections.

  • Patent number: 6147871
    Abstract: A low profile riser card assembly for a computer system is provided by incorporating two uniaxial back to back peripheral connectors. The peripheral card connectors extend outwardly along a single axis from opposing sides of a riser card. The riser card is attached to a riser card connector mounted on the circuit board and is held in a perpendicular to the axis and in an upright position with respect to the circuit board. In the assembly of the present single invention, the uniaxial back to back peripheral card connectors are retained on the riser card in a parallel orientation with respect to the riser card connector to produce a low profile computer assembly.

  • Patent number: 6134772
    Abstract: The present invention permits solder joints to be made directly to via and through holes without the solder being wicked into the vias or through holes, by filling plated through holes with an epoxy or cyanate fill composition. When cured and overplated, the fill composition provides support for the solder joint and provides a flat solderable surface for the inter-connection. In certain embodiments, the cured fill compositions, offer a further advantage of being conductive. The invention also relates to several novel methods for filling through holes with such fill compositions, and to resistors located in through holes and vias.

  • Patent number: 6099959
    Abstract: In accordance with the present invention, a method of treating the surface of an organic substrate, particularly a circuitized surface of an organic substrate, which method reduces the spread of adhesive resin that is subsequently deposited on the surface, is provided. This method comprises the steps of applying a treatment solution comprising a fatty acid compound, an alkalizing agent, and a solvent comprising water and from about 5% to about 90% by volume of an organic solvent selected from the group consisting of an alcohol, a glycol ether, and combinations thereof to the surface; and then removing substantially all of the solvent from the solution to provide a thin film on the surface of said substrate. The film comprises the fatty acids that were present in the treatment solution. In a preferred embodiment the treatment solution further comprises a chelating agent.
