A flexible, high density decal and the use thereof methods of forming detachable electrical interconnections between a flexible chip carrier and a printed wiring board. The flexible decal has fine-pitch pads on a first surface and pads of a pitch wider than the fine pitch on a second surface, the fine-pitch pads on the first surface designed to electrically connect to a semiconductor device, and the wider-pitch pads on the second surface designed to electrically connect to a printed wiring board or the like. The pads on the first surface are conductively wired to the pads on the second surface through one or more insulating levels in the flexible decal.

Method of joining a semiconductor device/chip to a printed wiring board

A method of improving conductive paste connections in a circuitized substrate in which at least one and preferably a series of high voltage pulses are applied across the paste and at least one and preferably a series of high current pulses are applied, both series of pulses applied separately. The result is an increase in the number of conductive paths through the paste connections from those present prior to the pulse applications and a corresponding resistance reduction in said connections.

Method of improving electrical connections in circuitized substrates

An electronic card assembly is provided which includes a protective housing having a movable card therein. The card, in one example one having a magnetic stripe, has its information erased when being inserted into the housing and re-written back onto its information portion (magnetic stripe) during card withdrawal, provided appropriate human information (e.g., from a fingerprint) is received by the assembly's reader component.

Electronic card assembly

A method and associated structure for forming a conductive path within a laminate. A conductive element is presses into an opening in the laminate such that portion of at least one end of the conductive element extends beyond a surface of the laminate. A compressive pressure is applied to the portion of the at least one end of the conductive element. The compressive pressure applied to the at least one end of the conductive element forms a contact pad extending beyond the surface of the laminate. The conductive element may include an inner element covered by an outer element.

Method and apparatus to establish circuit layers interconnections

A multi-layer electronic structure includes an increased capacity for the attachment of active or passive devices thereto. This is achieved by creating a three-dimensional grid of connection points to electrically couple active or passive surface mounted devices to edge mounted devices. The grid pattern is useful with any laminate including circuit cards, ceramic modules and flexible circuits. The variety of electrical devices that may be connected to the cross-sectional substrate includes, but is not limited to, chips such as semiconductor chips, diodes, resistors, capacitors and printed wiring boards. The structure can be used to more rapidly pass data, such as optical data that is transmitted from a spectroscope through a VCSEL laser and the electronic structure to a computer for diagnostics and analysis. A stepped arrangement of circuitized laminates is described for this purpose.

Multi-layered high density connections

An arrangement and method for the insertion the leading end of a length of a metallic element into a through hole which is formed in a substrate, and for heat deforming the inserted leading portion of the metallic element into a predetermined configuration prior to severing therefrom the remaining length of the metallic element.
