Abstract: A power interconnection system comprising a plurality of z-axis compliant connectors passing power and ground signals between a first circuit board to a second circuit board is disclosed. The interconnection system provides for an extremely low impedance through a broad range of frequencies and allows for large amounts of current to pass from one substrate to the next either statically or dynamically. The interconnection system may be located close to the die or may be further away depending upon the system requirements. The interconnection may also be used to take up mechanical tolerances between the two substrates while providing a low impedance interconnect.

Abstract: A directionally conductive polymer (DCP) provides an electrical interconnect between terminal or conductors on a pair of electrical components. The DCP is applied in viscous film form to the interface between the two components. The DCP comprises a resinous matrix containing metal particles in an amount normally causing the film to act as an electrical insulator. Electrical conduction through the film is normally inhibited in an unstressed state. When a stress is applied to the film, the metal particles make contact to form a continuous electrical path through the film in alignment with the applied stress. The metal particles maintain electrical insulating properties in regions of the film not subjected to the applied stress. In one embodiment, the film includes a metal polymer dispersed in a dielectric carrier resin. A first resinous material dissolved in a solvent contains a dispersion of metal particles. The dielectric material comprises a second resinous material dissolved in the same solvent.

Abstract: A polymer film interconnect forms an electrical interconnect between a first pattern of electrical conductors on a first electrical component and a second pattern of electrical conductors on a second electrical component. The polymer film interconnect includes a thin, flexible, self-supporting dielectric polymeric film having a pattern of spaced apart thru-holes containing separate quantities of an electrically conductive bonding material capable of heat bonding to the first electrical conductors adjacent the first surface of the film and to the second conductors adjacent the second surface of the film. This provides a plurality of discrete electrically isolated conductive paths from the first pattern of electrical conductors through the film to the second pattern of electrical conductors on the opposite side of the film.

A plurality of separate spaced apart recessed regions may be molded in an edge of the substrate and aligned with the castellations. A plurality of metal conductors are plated to the substrate as separate conductive circuit traces, so that each circuit trace extends continuously from the top surface, along the surface of a corresponding recess and to a common plane on a respective castellation at the bottom of the substrate. The plated metal castellations are arranged for soldering or gluing to contacts on a printed circuit board for electrical connection to an electrical component such as an IC chip connected to the circuit traces on the substrate.

The cavity is ringed with connectors which contact the spreader leads and appropriately connect the integrated circuit chip to other electronic components mounted on the substrate.

Abstract: A method of attaching semiconductor die to a package substrate and a composition for such die attach is disclosed, which method and composition comprise the combination of a low and a high-melting powder with a vehicle consisting of a solvent and a binder so as to form a thick-film ink. The ink is deposited onto the package substrate and the semiconductor die with a metallized back surface is located in contact with the deposited ink. The package containing the ink and the die is heated to a temperature of approximately 160.degree. C. so as to remove the solvent from the powders and the residual binder. Next, the package is fired at a temperature within the range of approximately 200.degree. C. to 430.degree. C. so as to melt the low-melting powder which bonds the chip to the package substrate. Then, a lid is sealed over the die-receiving cavity of the package by heating the package and the bonded die to a temperature within a range of approximately 400.degree. C. to 450.degree. C.
