Abstract:
A multi-chip electronic package and methods of manufacture are provided. The method includes contacting pistons of a lid with respective ones of chips on a chip carrier. The method further includes separating the lid and the chip carrier and placing at least one seal shim on one of the lid and chip carrier. The at least one seal shim has a thickness that results in a gap between the pistons with the respective ones of the chips on the chip carrier. The method further includes dispensing thermal interface material within the gap and in contact with the chips. The method further includes sealing the lid to the chip carrier with the at least one seal shim between the lid and the chip carrier.

An improved thermal interface material for semiconductor devices is provided. More particularly, low compressive force, non-silicone, high thermal conductivity formulations for thermal interface material is provided. The thermal interface material comprises a composition of non-silicone organics exhibiting thermal conductivity of approximately 5.5 W/mK or greater and a compressed bond-line thickness of approximately 100 microns or less using a compressive force of approximately 100 psi or less.
Abstract:
An optical-electronic package for an electronic device provides electrical connections to the electronic device and optical fiber connections to the electronic device. The package includes a high thermal conductivity base which has a pedestal to support and provide heat transfer connection to the electronic device. A seal band is formed on the base and a casing is bonded to the seal band. The casing has side feedthroughs for the electrical connections from the electronic device, and the casing has top feedthroughs or grooves for the optical fiber connections from the electronic device. A lid is hermetically sealed to the top of the casing. The lid has retractable means for forming a bend in the optical fibers to provide strain relief when the lid is placed on the casing. The retractable means for forming a bend in the optical fibers is retractable once the lid is sealed on the casing.

An apparatus for integrating optical devices between a module and a circuit board comprising a carrier having optical waveguides, a module having optical ports on a surface of the module, the surface of the module connected to the carrier such that the optical waveguides are in communication with the optical ports; and a circuit board having optical ports on a surface of the circuit board, the surface of the circuit board connected to the carrier such that the optical waveguides are in communication with the optical ports. The apparatus may also integrate electrical ports on the surface of the module, the surface of the circuit board, and electrical connections on the carrier. The apparatus may also integrate circuit chips having optical ports for communication with the optical waveguides.
Abstract:
A process for producing ultra-fine particles of calcia-stabilized zirconia in which a precursor mixture (which contains from about 80 to about 96 mole percent of zirconium ion, from about 20 to about 4 mole percent of calcium ion, a nitrogen-containing fuel, and a solvent) is dried and then subjected to a temperature of from about 275 to about 750 degrees centigrade and an atmosphere with a relative humidity of less than about 60 percent, thereby causing the dried particles to react in a vigorous manner and to form a combusted powder.

Abstract:
The present invention provides chip containing electronic devices such as Multichip Ceramic Modules (MCM's) containing a plurality of chips on a substrate which chips are underfilled with a reworkable composition which allows one or more chips to be removed from the device and replaced. The reworkable compositions contain a base resin which is not cross-linkable and which forms a matrix with a linear curable component or preferably a combination of linear curable components which curable components are cross-linkable and when cured form a cross-linked domain in the base resin matrix. A suitable cross-linking catalyst such as Pt is used and optionally a filler preferably silane surface treated silica. The preferred base resin is linear polydimethylsiloxane and the preferred curable components are vinyl terminated linear poly dimethyl siloxane and hydrogen terminated linear poly dimethyl siloxane.
Abstract:
An apparatus for determining a magnitude of a compressive load applied to a piston including a compliant film disposed between first and second elements is provided. The apparatus includes a first part movable with the first element in a movement direction along which the magnitude of the compressive load is to be determined, a second part movable with the second element in the movement direction and a sensor to measure a distance between the first and second parts in the movement direction, the measured distance being related to a deformation of the compliant film as the compressive load is applied.
