    摘要: The present invention is directed to a high density test probe which provides a means for testing a high density and high performance integrated circuits in wafer form or as discrete chips. The test probe is formed from a dense array of elongated electrical conductors which are embedded in an compliant or high modulus elastomeric material. A standard packaging substrate, such as a ceramic integrated circuit chip packaging substrate is used to provide a space transformer. Wires are bonded to an array of contact pads on the surface of the space transformer. The space transformer formed from a multilayer integrated circuit chip packaging substrate. The wires are as dense as the contact location array. A mold is disposed surrounding the array of outwardly projecting wires. A liquid elastomer is disposed in the mold to fill the spaces between the wires. The elastomer is cured and the mold is removed, leaving an array of wires disposed in the elastomer and in electrical contact with the space transformer The space transformer can have an array of pins which are on the opposite surface of the space transformer opposite to that on which the elongated conductors are bonded. The pins are inserted into a socket on a second space transformer, such as a printed circuit board to form a probe assembly. Alternatively, an interposer electrical connector can be disposed between the first and second space transformer.

    摘要: A wafer-scale apparatus and method is described for the automation of forming, aligning and attaching two-dimensional arrays of microoptic elements on semiconductor and other image display devices, backplanes, optoelectronic boards, and integrated optical systems. In an ordered fabrication sequence, a mold plate comprised of optically designed cavities is formed by reactive ion etching or alternative processes, optionally coated with a release material layer and filled with optically specified materials by an automated fluid-injection and defect-inspection subsystem. Optical alignment fiducials guide the disclosed transfer and attachment processes to achieve specified tolerances between the microoptic elements and corresponding optoelectronic devices and circuits. The present invention applies to spectral filters, waveguides, fiber-optic mode-transformers, diffraction gratings, refractive lenses, diffractive lens/Fresnel zone plates, reflectors, and to combinations of elements and devices, including microelectromechanical systems (MEMS) and liquid crystal device (LCD) matrices for adaptive, tunable elements. Preparation of interfacial layer properties and attachment process embodiments are taught.

    摘要: A flex circuit card with an elastomeric cable connector assembly is provided for transmitting high speed signals between two or more printed circuit boards in a high performance computer system. The flex circuit card connects a cable assembly to a printed circuit board. A conductor trace in the flex circuit card extends into an elastomeric end and terminates with a ball shaped contact which is angled to wipe against mating pads on the printed circuit card for making electrical contact. The cable assembly uses multiple wires attached to a plurality of elastomeric connectors. At least one elastomeric connector is attached to each end of the cable assembly and each elastomeric connector has a plurality of contacts which are used to mate with a plurality of pads on the surface of the printed circuit board. The elastomeric connector described in the present invention provides a high density, cable-to-board interconnection that is perpendicular to the surface of the printed circuit board.
