Abstract: An interposer for a land grid array includes a dielectric grid having an array of holes and a resilient, conductive button disposed in one or more of the holes. The button includes an insulating core, a conducting element wound around the insulating core, and an outer shell surrounding the conducting element. The characteristics of the conducting element and the buttons may be chosen such that the contact force and resistance, and compressibility or relaxability of the conductive buttons can be selected within wide limits. Contact areas between the shell and the conducting element urge a substantially corresponding displacement in both the conducting element and the shell when the button is under compression or relaxation. The interposer alternatively can include an insulating sheet and rather than conductive buttons contain conducting elements disposed therein having contact areas with the block. The interposer when positioned between a land grid array and an electrical circuit component can accommodate relatively large nonplanarity between respective mating surfaces of the two interconnected components while establishing and maintaining contact between each conducting element and the opposing contact pads of each component. A high local contact force is produced at each end of the conducting element against an opposing electrical contact or contact pad of a circuit device to establish a good electrical connection with the interposer which thus electrically interconnects the land grid array and the circuit component. The new interposer design is eminently amenable to high frequency and high current applications.

Abstract: A large flat panel display having a plurality of tile display modules with capability in the range of 12 or more lines per inch, being precisely manufactured and aligned such that the interpixel spacing between two adjacent tiles maintains the uniformly periodic spacing of the interpixel spacing within tiles. The display is addressed as a single monolithic display, without reference to the plurality of individual tiles making up the display. All of the interconnections between tiles are located between tiles in the “shadow area”, unless all tiles can have an edge around the periphery of the display. Also disclosed are methods of making and assembling the tiles and the displays.

Abstract: The present invention features methods and apparatuses for sealing tiled, flat-panel displays (FPDs). Tile edges corresponding with the display's perimeter edges are designed with a wide seal. Interior edges, however, have narrow seals in order to maintain the desired, constant, pixel pitch across tile boundaries. In some cases, this invention applies specifically to arrays of tiles 2.times.2 or less, and, in other cases, to N.times.M arrays, where N and M are any integer numbers. The tiles are enclosed with top and bottom glass plates, which are sealed with an adhesive bond to the tiles on the outside perimeter of the tiled display. Vertical seams (where tiles meet at the perimeter of the FPD) are sealed with a small amount of polymer. The seal may be constructed between a cover plate and a back plate, sandwiching the tiles. The AMLCD edges may be coated with either a non-permeable material or a polymer having an extremely low permeability (for example, Parylene.TM.). Alternatively, the edge sealing of individual tiles can be achieved by using a metallized film adhesive that is bonded to the tile edges. A low-temperature, sintered Solgel can be used to achieve extremely narrow, yet mechanically strong, seals for individual tiles. Still another enhancement employs a metallurgical seal outside a narrow, polymer seal.

Abstract translation: 本发明的特征在于用于密封平铺平板显示器（FPD）的方法和装置。 对应于显示器周边边缘的平铺边缘设计有广泛的密封。 然而，内部边缘具有窄的密封，以便在瓦片边界上保持所需的恒定的像素间距。 在某些情况下，本发明特别适用于2×2以下的瓦片阵列，在其他情况下，适用于N×M阵列，其中N和M是任何整数。 瓷砖用顶部和底部玻璃板封闭，玻璃板通过粘合剂粘结在瓷砖显示器的外周边上的瓷砖上。 垂直接缝（其中瓷砖在FPD周边相遇）用少量聚合物密封。 密封件可以构造在盖板和背板之间，夹住瓦片。 AMLCD边缘可以涂覆有非渗透性材料或具有极低渗透性的聚合物（例如，Parylene TM）。 或者，各个瓦片的边缘密封可以通过使用结合到瓦片边缘的金属化膜粘合剂来实现。 低温烧结的Solgel可用于为单个瓷砖获得极窄但机械强度的密封。 另一个改进是在窄的聚合物密封之外采用冶金密封。

A method for forming a precursor material for use in man-ufacturing an electrical contact is also provided that includes ma-nipulating a plurality of wires so as to interlace the wires into a unitary structure. The unitary structure is then annealed. An electrical contact may then be formed from the precursor mate-rial by elastically rolling a portion of the unitary structure so as to form a tube, annealing the tube, and then cutting the unitary struc-ture so as to release the tube thereby to form an electrical contact. An electrical contact may also be formed by folding a portion of the unitary structure so as to form one or more pleats, annealing the pleated unitary structure, and then cutting the pleated unitary structure so as to release one or more electrical contacts. The pre-cursor material may also be formed by photo-etching a sheet of conductive material so as to form a mesh, and then annealing the mesh. A connector system may be formed including a housing defining a plurality of openings that are each filled with an elec-trical contact comprising a plurality of interlaced and annealed wires that have been previously either rolled or pleated.

Abstract: The present invention is a family of memory modules. In one embodiment a memory module with granularity, upgradability, and a capacity of two gigabytes uses 256 MB SDRAM or DDR SDRAM memory devices in CSPs in a volume of just 4.54 inches by 2.83 inches by 0.39 inch. Each module includes an impedance-controlled substrate having contact pads, memory devices, and other components, including optional driver line terminators, on its surfaces. The inclusion of spaced, multiple area array interconnections allows memory devices to be symmetrically mounted on each side of each of the area array interconnections, thereby reducing the interconnect lengths and facilitating the matching of interconnect lengths. Short area array interconnections, including BGA, PGA, and LGA options or interchangeable alternative connectors provide interconnections between the modules and the rest of the system. Thermal control structures may be included to maintain the memory devices within a reliable range of operating temperatures.
