  • Patent number: 7037160
    Abstract: A color cathode-ray tube (CRT) having an evacuated envelope with an electron gun therein for generating at least one electron beam is provided. The envelope further includes a faceplate panel having a luminescent screen with phosphor elements on an interior surface thereof. A focus mask, having a plurality of spaced-apart first conductive strands, is located adjacent to an effective picture area of the screen. The spacing between the first conductive strands defines a plurality of apertures substantially parallel to the phosphor elements on the screen. Each of the first conductive strands has a substantially continuous insulating material layer formed on a screen facing side thereof. A plurality of second conductive wires are oriented substantially perpendicular to the plurality of first conductive strands and are bonded thereto by the insulating material layer. The insulating material layer comprises a low porosity lead-zinc-borosilicate glass.

  • Patent number: 6653741
    Abstract: A thermal interface material for use in electronic packaging, the thermal interface material comprises a solder with relatively high heat flow characteristics and a CTE modifying component to reduce or prevent damage due to thermal cycling. The thermal interface material comprises an active solder that contains indium and an intrinsic oxygen getter selected from the group consisting of alkali metals, alkaline-earth metals, refractory metals, rare earth metals and zinc and mixtures and alloys thereof. Lastly, damage due to an electronic package due to thermal cycling stress is reduced by using an insert in a lid of an electronic device package wherein the insert has a coefficient of thermal expansion that is between about that of the lid and about that of a semiconductor substrate.

  • Patent number: 6551720
    Abstract: Materials for making a plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. The dielectric material is made from a green ceramic tape which is bonded to the core and cofired with the core to form the back panel. The materials for the dielectric can be chosen such that the composite TCE of the cofired assembly matches the TCE of the front panel.
